JoJo Monitor Tank Level

Device Specific

Activate your device:
To activate your device, press the activation button on the front once (no longer than 1 second). Upon release you will hear 4 long beeps followed by 1 short beep to confirm that it has been activated. If you only hear 1 single beep, the device is already activated and ready for use.

If you have replaced the batteries and are now struggling
to turn it on:
Please ensure that they are 3.6v lithium batteries, inserted in the correct orientation and are not flat or a combination of old and new batteries.

If you have already tried to activate your device and have not yet changed the batteries:
Please submit a request for assistance via the Help and Troubleshoot section in the JoJo Monitor app for us to assist and advise accordingly.

This occurs when the bottom of the sensor gets wet and/or due to heavy build-up of condensation against the roof/lid of the tank directly underneath the sensor. Once the water has been removed your device will report accurately.

The serial number is on a label at the back of your device, as well as on the inside of the box and is unique to your device. We recommend taking a clear photo of this to ensure you have a record readily available for setup, future reference and troubleshooting purposes. We also advise keeping this safe and not sharing it with anyone else.

Your model number is on a label at the back of your device.

The button on the front of your device can be used for various functionalities including:


Activating the device:
By pressing the button once after which you will hear 4 long beeps followed by 1 short beep. If you only hear 1 single beep, the device is already activated and ready for use.

Putting the device in test mode:
By pressing and holding the button for 5 seconds until you hear 2 long beeps, during test mode you can then align your sensor while installing it and the faster the beeps the better the signal (which is influenced by the sensor orientation). Test mode is exited by pressing the button again once, or it will conclude automatically after 10 minutes.

Disabling the device/putting it in Flight Mode:
By holding the button for 3 seconds followed by 10 consecutive short presses, after which you will hear the following beeps: 3 long, 2 short, 1 long, 3 short, 1 long and 1 short. Note: the unit will not transmit over Sigfox or be visible via Bluetooth when in this mode and will need to be activated again by pressing the button once.

Resetting the device:
By holding down the button for 3 seconds and then releasing it three times in a row. You will hear 3 short beeps indicating that it has been successfully reset.

Device successfully activated = 4 long beeps, 1 short beep
Test mode enabled = 2 long beeps

While in test mode the buzzer is influenced by alignment and will sound with periodic beeps to indicate signal quality with indication as follows:

Bad signal = 3 seconds between beeps
Good signal = fast consecutive beeps

Should the beeping not stop
Please log a request for assistance via the Help and Troubleshoot section in the JoJo Monitor app.

Please ensure that the serial number has been entered correctly, if it has and the problem persists, please submit a request for assistance via the Help and Troubleshoot section in the JoJo Monitor app so that we can assist and advise accordingly.

Ensure that there is a minimum gap of 150mm between the highest possible level of water and your sensor for consistently accurate readings.

The batteries typically need to be replaced every two years, this will vary based on the reading frequency set as part of Sigfox monitoring, and how often live readings are retrieved via Bluetooth. It is advised to keep an eye on your battery status on your dashboard, when it is red it is running low and needs to be replaced.

The device is designed to monitor water levels inside tanks, any other liquids may result in inaccurate readings.

Whenever you are within Bluetooth range of your device, and your app is open, Bluetooth readings will automatically be taken every 10 seconds. Note: it is advised to not take readings while the tank is filling with water as this may impact the accuracy of the readings being taken.

This could occur due to the following:

As a result of water
When condensations builds up underneath the sensor.
When the sensor gets wet (potentially from water splashing while your tank is filling up).


Ensure that nothing is obscuring, blocking or condensed under the sensor. Once the sensor is dry again the above will be resolved automatically.

As a result of incorrect installation
When installed closer to the highest water level than recommended (the recommended distance between the highest water level and your sensor is a minimum of 150mm).
When not installed level.

Ensure that your device is installed as per our guidelines provided.

If the error persists please submit a request for assistance so that we can advise accordingly.

Connectivity

Ensure that your device has been activated (this should be done when linking your device to your account by pressing the button on the front of the device once). Remember to enable Bluetooth on your mobile phone and to grant the JoJo Monitor app access to Bluetooth (this can be done via the prompts when creating your account or from the application settings). If the problem persists after all of the above, please submit a request for assistance via the Help and Troubleshoot section in the JoJo Monitor app.

You can visit https://www.sigfox.com/en/coverage to check the coverage in your area. If however your area does not have coverage, you can still use our device utilising Bluetooth to retrieve readings when within proximity of your device.

This device can be utilised with Bluetooth and/or Sigfox, each type of connectivity offers different functionalities, which are as follows:

Bluetooth – used for initial activation, testing and live readings or real-time monitoring when within close proximity of your device.

Sigfox/Remote Monitoring – allows you to access current and historic data, configure alerts and notifications, and view/compare water storage and/or usage over given periods.

Red – Poor Sigfox connection
Orange – Moderate Sigfox connection
Grey – No Sigfox reading received within 24 hours
Green – Good Sigfox connection

If you are in an area with Sigfox coverage and were previously able to connect and get readings via Sigfox, this is most probably due to a temporary Sigfox network issue in your area. This could be due to maintenance being carried out on one of their base stations or an alternative base station connection issue. In this instance we cannot confirm how long the base station will be down for, but if the problem persists, please submit a request for assistance via the Help and Troubleshoot section in the JoJo Monitor app and we will look into it and do our best to advise accordingly.

Installation

The monitor device needs to be installed with the activation button facing upwards, and the sensor needs to be installed as close to the centre of your tank as possible, ensuring that it is 100% level and at least 150mm above the highest possible water level of the tank.

It is recommended to install your sensor as close to the centre of the tank as possible, ensuring that it is 100% level and at least 150mm above the highest possible water level of the tank. Please refer to the installation guidelines provided on the packaging for detailed information, as well as placement recommendations for various types of JoJo tanks.

Linking your device to your App

Ensure that your device has been activated by pressing the activation button on the front once (for no longer than one second). If after this the problem still persists, please submit a request via the Help and Troubleshooting section in the app in order for us to assist and advise accordingly.

Ensure that your mobile device’s Bluetooth is on and that you have granted the JoJo Monitor app permission to use Bluetooth. If you have, and the error persists, please submit a request for assistance via the Help and Troubleshoot section in the JoJo Monitor app so that we can assist and advise accordingly.

This sometimes occurs with Apple devices due to Bluetooth connectivity issues. If this occurs, log out of the app and restart it, go back to that same screen and the device should link successfully.

Tank setup / calibration

Please go through the configuration journey and ensure all details provided are correct. You can also customise your configuration via the “Calibrate my Device” button on the Details section of your dashboard. This can be done manually, or by taking live readings via Bluetooth.

Should this occur, please reset your password from the login screen.

Always ensure you are running the latest version, it is much easier if you set the app to auto update whenever there is a new release. If you prefer to do updates manually, you can do so via the app store or in the application settings on your mobile phone.

Please submit a request via the Help and Troubleshoot section in the JoJo Montor app for us to assist and advise accordingly.

Please ensure that you are running the latest version of the app, and that you have an internet connection (which is required to save the configuration on the server). If you are not connected to the internet, the configuration will only be saved on your mobile device where the configuration was added/changed. If you do have the latest version and your device was connected to the internet during the configuration setup, please submit a request via the Help and Troubleshoot section in the app in order for us to assist and advise accordingly.

Ensure you have a proper internet connection, if you do and the problem persists please submit a request for assistance via the Help and Troubleshoot section in the JoJo Monitor app so that we can assist and advise accordingly.

You can always confirm this within the “About JoJo Monitor” section in the JoJo Monitor app. The latest version and release date will be stated there with each new release.

Alerts are setup separately for each device. To edit alerts for your device or one of your devices, select the relevant device from your list of devices, go to “alerts” and select the edit button next to warning and/or notifications. This will take you to  your alert setup and allow you to make edits as desired.

Firstly, ensure that you have Alerts for Overflow enabled within your app. If this has been enabled, the overflow alert is triggered when water exceeds 35mm above the highest level set for the tank.

The JoJo Monitor app will function on Android Go, however due to the limitations of the device’s hardware, the app will close when the device is locked.

General

The measurable range of the sensor is 150mm to 5 000mm.

Filtration Range

Filter Bottle

The breather on top of the Filter Bottle is what makes the noise. Although different, this is needed to let the air back into the bottle while you drink. Keep in mind that the JoJo Filter Bottle is different from normal water bottles, as it filters the water while you drink.

An average of 210 litres, which amounts to 300 refills. To be safe, it is advised to replace your Filter Cartridge at least once every two months.

Because water quality and volume of consumption varies, filter service life will also vary. A drop in pressure is the easiest way to tell if your filter needs to be replaced. When using the bottle, this will be evident when you struggle to sip the water from the bottle (more than you normally would).

Yes. Remove the filter (the filter should never be washed as it will try to filter out the soap and this will shorten its lifespan), then place the bottle upside down on the top shelf of your dishwasher.

Yes it is, and it is safe to use continuously for everyday use as it was specifically designed for that purpose.

The water flow is slower because it filters the water while you drink. It is important to remember that this is not just a water bottle, it is a JoJo Water Filter Bottle.

Countertop/Undersink Filter

The JoJo Countertop Filter Unit has everything you need for easy DIY-installation. Download our user manual or watch this video for all the information required for installation.

The Undersink Filter is a little trickier to install than the Countertop Filter, as it requires you to tie into the water supply underneath your sink. It is advised to make use of a licensed plumber or preferred JoJo installer to avoid forfeiting the warranty due to incorrect installation. Note: ensure you keep your proof of installation should you need it at a later stage for warranty purposes. For detailed installation instructions download our user manual or watch this video.

No, the system can only filter water between 4 and 38 ˚ C. Using hot water can damage your filter media.

It is advised to only use cold tap water.

An average of 3000 litres. To be safe, it is advised to replace your Filter Cartridges at least once every six months. Alternatively, if there is a significant drop in pressure when the filters need to be replaced. Due to the quality variation in water and consumption volumes, the lifespan will vary.

Simultaneously, gently press the blue stopper and the collar of the fitting in towards the filter.

Then, while keeping the collar of the fitting pressed in, pull the blue stopper out.

It has a safety feature that prevents it from leaking or releasing when pressure goes through it. Remove the blue retaining clip, then push the white pipe further into the connection, and while keeping the collar of the inlet fitting pressed in, gently pull the pipe out.

It is recommended to replace them every 6 months, or after every 3000 litres filtered. If you live in an area with a lot of sediment in the water, you can however replace your PP Sediment more often to protect the Disruptor Filter and expand its lifetime (as it is the most expensive of the two filters).

Both the units have a three-year warranty (consumable parts only covered for manufacturing faults and defects).

Inline Filter

An average of 1500 litres or 8 to 12 months for optimum filtration (if used as a backup solution and not permanently). Note: because water quality and volume of consumption varies, filter service life will also vary.

It depends on the pressure and application; the unit needs a minimum of 1 bar pressure to operate and the maximum pressure should never exceed 4 bars.

The average flow rate is 3 litres per minute, this could vary depending on the operating pressure.

It is supplied with click-on-hose fittings that easily connect to standard clip-on hose connectors (not included).

It is important to note the direction of flow (indicated on the filter). The filter only functions in one certain direction and the inlet and outlet are clearly marked for exactly this reason.

This will vary depending on use, but if used with a hose you will require a supply and outlet hose (you can cut your hose in two if you want), as well as 2 x clip-on hose connectors.

Whole-house Filter

It is advised to make use of a licensed plumber or preferred JoJo installer when installing the Whole-house Filter, as it ties into your mains supply outside the house. This also avoids forfeiting the warranty due to incorrect installation. Note: ensure you keep your proof of installation should you need it at a later stage for warranty purposes. For detailed installation instructions download our user manual.

The correct combination will vary depending on the water source and your requirements. For example, if you have a filter for your drinking water and only want to use this filter to remove sediment and chlorine to improve the overall quality of your water for various household uses, you might only need a PP Sediment Cartridge (as the first stage of filtration) and a PP Activated Carbon Cartridge (as the second stage of filtration). If you want to use the filter to ensure all the water you use inside your home is not only clean, but safe, you need to use a Disruptor Cartridge. For more detailed guidelines on the correct combination for you, have a look at our guidelines.

Carbon and sediment filters serve two different functions. Sediment filters catch sediment and particulates, while carbon captures organic compounds that cause bad tastes and odours. A sediment filter is a mechanical filter. It has a certain porosity that water can flow through, but not anything larger than the micron rating of the filter. Because a carbon filter removes particles by adsorption, it does not make as good a sediment filter. You often need one of each, or alternatively one of the two combined with a Disruptor 5293 PAC-S Cartridge. It will depend on the application.

You can use municipal water, rainwater and even borehole water (if it has been tested and deemed safe for domestic use). It is important that the water source is appropriately controlled.

The Whole-house Filter operates optimally between water pressures of 50-480kPa, and the maximum pressure it can handle is 620kPa. Note: if the water source exceeds the maximum pressure, a pressure limiting valve may be needed.

An average of 80 kilolitres. This will vary depending on the combination of Filter Cartridges, water quality and volume of consumption. Alternatively, another indication that the filters need to be replaced would be a significant drop in pressure.

Disruptor Technology

Disruptor refers to a breakthrough technology, the first of its kind in SA. It is unique for the following reasons:

1. It uses a process called Electroadsorption to trap and remove viruses, bacteria and various other contaminants.
2. It contains Powdered Activated Carbon (PAC) to reduce odours and improve the taste of the water filtered.

3. It also contains Anti-Microbial Silver (S) to disinfect the filter.

Watch this video for more detail.

The 5293 refers to the model of the filtration media as specifically used for JoJo filter products.

Apart from all that it removes in order to make your water clean, safe and great-tasting, the additional benefits include:

  • Very high flow rates at lower pressure drops compared to competing technologies with similar biological removal performance.
  • Effective removal of pathogens and other contaminants while maintaining the minerals for taste.
  • As part of the filtration process, no water is wasted.

 

Here is some additional  information on the Disruptor technology.

Bacteria, viruses, parasites, sediment, chlorine, medication and more. You can find out more about the filtration media on our website.

Because water quality and volume of consumption varies, filter service life will also vary. Recommended filter use guidelines are provided on the packaging and on our website for each product within our range. This said, the easiest way to tell if your filter needs to be replaced is a drop in pressure.

Choosing a Filter

Point-of-use systems filter water at the point of use and is usually installed at a single water connection, typically under sinks or on top of counters in kitchens. Point-of-entry filtration solutions are also referred to as ‘whole-house water filters’. These units are installed at the main water line where the water first enters the home and treats all the water that enters your household.

The type of filtration solution you require will be determined by your water source, the quality of the water, the desired application and personal preference. For example:

  • If you want a mobile water solution for everyday use, the Filter Bottle is ideal.
  • If you want drinking water for your entire family, the Undersink Unit is ideal, especially if you want an out-of-sight solution. If you are renting and don’t want to drill any holes, the Countertop Unit is your perfect solution.
  • If you camp frequently or need to make use of water stored in a tank of which the quality is uncertain, our Inline Disruptor Filter is a good option.
  • If you want to filter the water in your entire house, the Whole-house Filter will do just that and has a variety of Filter Cartridge combinations to suit your requirements.

All JoJo filter casings and housings are 100% recyclable. The Filter Cartridges however, are not.

Accessories

Tank Mozzie Screen

Mosquitoes love stagnant water, and could become a nuisance if you have a water tank that is not properly installed and secured at all connection/entry points. Our Tank Mozzie Screen is ideal to use for exactly this purpose, as it is a cost-effective way to keep mozzies at bay while still allowing water to escape from your overflow and promoting air ventilation and circulation.

This will vary depending on where you would like to fit the Tank Mozzie Screen and the year you purchased your water tank. In the beginning of 2020, we designed a new Full Thread Reducer (now used as the standard fitting for all Vertical and Slimline Water Storage Tanks) that allows for internal and external connections. If you bought a tank prior to the year 2020, you will only be able to fit the Mozzie Screen to the outside of your inlet/overflow. However, if you would still like to install the Mozzie screen to the inside of your tank, you can purchase the 50/40mm Full Thread Reducer separately.

Full Thread Reducer

The old reducer will have thread from the outside of the fitting half-way through the inside of the fitting. The new Full Thread Reducer will have thread throughout the fitting. View our product page with a photo for reference and usage guidelines.

Tanks

Material Used

JoJo uses the best food-grade quality LLDPE (linear low-density polyethylene) for all our roto-moulded products, with the exception of septic and conservancy tanks, which are manufactured with recycled plastic in order to reduce destructive waste output. View our quality commitment for more detail on why JoJo tanks are the best possible choice when it comes to water storage.

Yes they are and this UV-resistance gives them their durability in harsh SA weather conditions and prevents them from breaking down or becoming weak over time.

Yes – we use the best food-grade quality virgin LLDPE for our products and our tanks cannot cause any damage to water. Our tanks are UV resistant, and all our water tanks are lined with an FDA approved food grade carbon black lining to prevent algae growth and protect the quality of stored water.

Warranty

JoJo tanks have a 10 year-warranty (extended from 8 years as of 1 September 2017) on material and workmanship. However properly installed JoJo tanks have been known to exceed a lifespan in excess of 20 years. Smaller items and products have different warranty periods, these can be viewed on individual product pages.

Installation and maintenance of a JoJo tank should be in accordance with the manufacturer’s specifications. If you drill any additional holes or make any alterations to the tank whatsoever, the integrity of the tank is jeopardised, and your warranty will fall away.

Additional Product Information

Density of water: When considering which plastic tank to use, it is important to know that they are rated based on the “specific gravity’ (SG) of the substance they are designed to hold. In other words, tanks with a higher specific gravity rating will have thicker walls and will be designed for heavier duty use when compared to another tank made from the same material but with a lower specific gravity. JoJo tanks are specifically designed for each intended purpose and it is necessary to specify the intended use prior to making a purchase. Specific gravity (SG) is the ratio of the density* of a substance to the density of a standard, usually water for a liquid or solid, and air for a gas. *Density: mass of the same unit volume, 1 lt water = equals 1 kg of weight, 1000 lt water = equals 1 ton of weight, 2500 lt water = equals 2,5 tons of weight. Contact us for recommendations and guidelines based on your specialised chemical-grading requirements.

(w) – abbreviation for water (SG 1)
(m) – abbreviation for medium (SG 1.4)
(h) – abbreviation for heavy duty (SG1.6).

An above ground JoJo tank cannot handle any additional pressure (internal or external). That is why JoJo offers a 6000lt underground tank specifically designed to be installed below ground level. For something smaller, you can use any of our conservancy tanks varying from 1250lt to 2500lt. Although these tanks are normally used for sanitation purposes, they can also be used for rainwater or greywater harvesting, and are made strong enough to withstand the pressure from the soil when empty. Note: If any other tank is installed below ground level a retaining wall is required.

A JoJo tank is designed to withstand the full range of temperatures that occur throughout South Africa: However, liquid stored inside the tank should not exceed 40 ˚ C.

NO PETROL can be stored in a JoJo tank. However, it is safe to store diesel in any of our chemical medium tanks (based on the material we use), although with the price of diesel in mind, we would suggest that you consider using a chemical heavy duty.

A vertical tank is the familiar normal upright tank and is used for the storage of water, liquid fertilizers, chemicals and most other liquids. A Horizontal tank is also known as a transporter tank. It can be fitted onto the back of a LDV or a truck and can also be used to build a water-car. It is ideal to transport water to dry, rural areas or building sites. The chemical tanks are often used to transport and store liquid fertilizers, diesel, molasses, etc.

Choosing the right tank

When choosing a tank, the following should be taken into consideration:

1. Space

  • If you have limited space, our Slimline tanks are the ideal solution.
  • If you need a larger tank to store more water, but have height restrictions, the low profile or horizontal tanks will be the perfect choice.
  • If aesthetics are of concern, or no floor space is available, you have the option of an underground water tank.
  • Ultimately, if space is not a problem and optimal water storage is the goal, consider our larger vertical water tank range for maximum storage.
  • We always recommend buying the largest tank that space, budget and practicality allow.

2. Application

  • Rainwater Harvesting – consider the rainfall in your area, your roof size, and what you intend on using the water for. The biggest downfall of rainwater harvesting is lack of storage capacity.
  • Municipal Backup – consider how many people you require backup water for, as well as how long you would like your backup water to last. The average person in SA uses 150L per day.
  • Fully Integrated System – consider how much municipal water you would like available as backup, then add the amount of rainwater you would like to harvest. You will require more storage capacity for this system.
Installation

Tanks must be installed on a sound, level and smooth surface. Level paving will suffice, or a properly designed tank stand. Alternatively a concrete plinth needs to be built, ideally with a concrete surface bed at least 85mm thick.

The tanks should ideally be installed on a 100% level, solid concrete slab of no less than 85mm thick. We recommend that you compact the ground thoroughly to ensure a flat and stable surface. The slab should be at least 100mm wider than the diameter of the tank to ensure there is no overhang. Tanks can also be installed on our steel tank stands purposefully designed by our structural engineers. The tank stand heights vary between 1.5 meter, 3m, 4.5m, 6m and 9m high. Spaces between beams should be no more than 50mm apart. For detailed installation guidelines, please see Water Storage Solutions.

Yes – On our website you will find a list of preferred installers who are equipped and capable to install our tanks. Kindly contact any of them in your area to recommend and quote an installation that will suit your specific requirements. You can find our list of Recommended Installers here.

We recommend that you make use of the JoJo tank stands as they were designed by structural engineers. We are in no position to advise on a structure of any other kind.

In order to get enough pressure by using elevation, a tank stand with a height of at least 3m is required. This will provide pressure of approximately 0.3 bar. Standard municipal pressure is 4 bar (depending on the area). We would advise the use of a pressure pump (if possible) which provides 4 to 6 bar pressure and is more cost effective. Find out more about our pump range here.

There is a very specific, highly-recommended installation procedure for all sanitation tanks. Detailed instructions can be viewed here.

Maintenance

Depending on the size of the tank, when empty (and if it is not mounted on a tank stand etc), you can simply turn the tank on its side (on grass) and then using a broom/mop and some sunlight dishwasher you can easily clean it. Just make sure to hose out all of the soap when done.

It can be repaired by using a hot air gun to weld a piece of the same plastic as the tank over the split/crack on the inside and outside of the tank. Our sales team can assist with repairs nationally. If you have a JoJo tank that needs repairing, please send an email to productinfo@jojo.co.za so that we can assist accordingly.

Horizontal/Transporter Tanks

JoJo manufactures a wide range of Horizontal water and chemical tanks (from 240L to 5500L) suitable for use in agriculture, chemical and other industries. A Horizontal tank is also known as a transporter tank and can be fitted onto the back of an LDV or a truck to build a water-car.

The tank is definitely suitable for rainwater harvesting, as long as you order a water tank and not a chemical tank. Note: No tank may be placed on bare ground, since it is not stable and the tank will be damaged by the uneven surface. All tanks must be placed on a solid foundation (a smooth and level concrete slab is ideal) of no less than 85mm thick. It is very important that the surface is level and smooth to ensure a robust base for the tank.

Underground Tanks

The 6000L underground tank has many uses: it can be used to store greywater and rainwater, it can also be used as a conservancy tank that can be pumped out and/or septic tank. It is the answer when space and accessibility are an issue – especially in an urban environment.

Yes – As long as it is a water tank. When ordering an underground tank for water storage purposes, it is important to specify this to ensure the black inner-lining is added as part of the manufacturing process. Our range of tanks that are suited for underground installation, are normally used for sanitation purposes and as a result are made from recycled plastic instead of food-grade plastic. See installation instructions for an underground tank here. Please also see installation instructions for rainwater harvesting here.

It is possible to clean an underground tank, by literally climbing into it and scrubbing with a brush and any liquid dishwashing soap. The opening of the tank at the top is 410mm, which is wide enough for a person with a slight build to climb through.

Septic/Conservancy Tanks

A septic tank: is designed for the disposal of sewage only, and brings about the digestion of organic matter and discharges the black water into a French drain to soak-away into the ground over time.

Conservancy tank: disposes of both black and grey water, and is used for temporary storage until the waste is pumped out by a honey-sucker. Often referred to as ‘heavy-duty’ septic tanks, their structural design is extra strong and sturdy enough to withstand the pressure from the soil when empty. It is important that the correct tank is used for the correct application in order to avoid damage to the tank and to ensure the system functions properly.The correct tank will be determined by the type of waste, as well as the desired application and disposal method. For more information click here.

The volume you would require will depend on how often the tank will be pumped out (if it is a conservancy) and how many people will use the facilities on a daily basis. 1 x hand / face wash = ± 1 – 4 lt water, 1 x toilet flush = ± 8 – 12 lt water, 1 x bath = ± 80 – 150 lt water, 1 x 5-minute shower = ± 80 lt water, 1 x 5kg load of laundry = ± 80 lt water (depends on model of washing machine, etc.).

No, soapy water or chemicals cannot be used as this will kill the bacteria and stop the normal functioning of the tank. “Septic Friendly” chemicals can be obtained from most co-ops or stores that specialise in outdoor products.

The digestion process can be enabled by using a starter pack (available at most outdoor stores or co-ops, or by simply putting a piece of rotten meat inside the tank).

If you want to use the tanks for water storage, it will be possible to connect two or more tanks. However, if used as septic/conservancy tanks, we strongly advise against it as the purpose of the septic tank is to separate solids from liquid. Even if the tanks are being used as conservancy tanks that can be pumped out, the tanks should not be joined and pumped out from one place only. If liquids are pumped out from one outlet, pipes will quickly become blocked, creating a huge problem.

Storing water inside a JoJo

Recommended Duration

In ideal circumstances municipal water can be stored inside a JoJo tank for a long time, as municipal water is chlorinated and safe to store for extended periods. Just be sure that the tank is properly sealed and that it is a water tank (with the food-grade black inner lining). It is recommended that the water is run once every two weeks to rotate the water and ensure that the best quality water is available.

Safety Measures

All JoJo water tanks are lined with an FDA approved food-grade carbon black liner that prevents algae growth and ensures your water will stay fresher for longer. A JoJo tank does not cause any damage to the water; the quality of the incoming water however may well be an issue. Please remember that water collected from the roof of a building will not be clean. If in emergencies you need to drink the water from the tank, it must be purified. The best way to purify small amounts of water is to bring it to a rolling boil for a minimum of one minute, thereafter it will be fit for human consumption. For irrigation purposes, however, the water would be perfect.

What tends to happen with long term storage is that water goes “flat”. To prevent that you can aerate your water. This is achieved by pouring water from one container to another a few times, at a slight height to re-introduce the air. You could also draw up a tank roster to rotate/circulate the water at set intervals by using that water for a few days to reduce the water level in your tank. Thereafter, you can refill with fresh municipal water (you could wash your car, fill up the pool, water the garden etc.).

Preference & Availability

Tanks

All standard fittings on tanks are included in the price. A special diesel fitting is required for all oil-based products, please ensure this is specified on your order (a diesel seal can be identified by its yellow nut). For detailed specifications on what each product is supplied with please refer to the specification sheets on each product page.

A variety of 20mm taps, e.g. plastic, lockable solid brass or nickel plated can be ordered separately at additional costs and a 40/20mm reducer is also needed to fit a tap to our standard water tanks. For more detail on our range of taps available, click here.

Yes, but please make your colour preference clear when ordering your kennel. View our full colour range available here. Also remember that the marble sandstone colour carries a premium of approximately 10% over the regular colours available.

Yes – just be sure to paint the tank with a plastic primer (obtainable from all co-ops and leading hardware stores) first, and thereafter with a good quality paint, e.g. Micatex that would shrink and expand simultaneously with the tank in all weather conditions.

Rainwater Harvesting

Amount of water that can be harvested

1mm of rain on 1m2 of roof surface amounts to 1 litre of water. For example: 5mm of rain on a 100m2 roof = 500 litres of water. Note: the efficiency will vary depending on roof surface, setup and pre-filtration method used.

Every installation is different. We suggest you buy the biggest tank that space, budget and practicality allow (see Rainwater Harvesting Solutions for more detail). The biggest downfall of rainwater harvesting systems is lack of storage capacity.

Rainwater Harvesting Installation

This depends on the scale of the project, small projects are perfect for the DIY guy, but larger projects are too risky to get wrong, get a pro.

With careful planning and execution, existing gutters require very few changes or alterations.

Thatch is about the only roof surface not suitable for rainwater harvesting, the others just vary in efficiency. Pitched or flat makes no difference.

Basic rainwater harvesting installations only incorporate a mesh at the top of the tank (underneath the lid) to keep out dust, leaves, mosquitoes etc. Additionally you can incorporate a rain head/leaf eater (removes larger debris) and a first flush diverter (takes off initial dirty water for every rainfall, improving the quality of water). The more pre-filtration devices installed, the better the quality of the water. For more detail on our range available, click here.

Mosquitoes love stagnant water, especially rainwater. The best way to keep them out of your tank is to ensure all connections are properly sealed. Mozzie Screens can be fitted to overflows and inlets that are not used as part of the installation to block entry for mosquitoes and other insects, while still allowing water to pass through.

All JoJo tanks are lined with an FDA approved food-grade carbon black liner that prevents algae growth and protects the quality of stored water. A JoJo tank does not cause any damage to the water, the quality of the incoming water however may very well be an issue. Please remember that water collected from the roof of a building will not be clean. Should you need to drink the water in an emergency, it must be purified or boiled before it will be fit for human consumption. For irrigation purposes however, the water would be perfect.

Maintenance

A well designed system needs little maintenance but never more than a pool would, for maintenance tips click here.

Municipal Backup

Tank Size

How much water is needed for municipal backup is dependent on two main factors, how many people will be utilising the water and how long you want the backup to last. The average South African uses 150 litres of water per day. Size of tank required = litres per day x total days back up required.

Municipal Backup Installation

The water can be accessed via a tap connected to the tank (this means you need to manually fill up a bucket or watering can as and when you need water). For easy access to your stored water, as well as a pressurized solution, we advise adding a pump to your installation. You can use the table on our website as a guide to find the right pump for your application, click here.

When a tap is opened, the pressure controller (built in) senses a drop in pressure and starts the pump operation, i.e. pumping water from the tank into the house.

Yes, there is. Our float valve kit allows for effortless filling with an automatic shut-off. This can either be done manually using a hose, or, for a more permanent and automated solution, you can connect it to your plumbing line.

In ideal circumstances municipal water can be stored inside a JoJo tank for a long time, because it is chlorinated and safe to store for extended periods. Just be sure that the tank is properly sealed and that it is a water tank (with the food-grade black inner lining). It is recommended that the water is run once every two weeks to rotate the water and to ensure that the best quality water is available.

Borehole Water Storage

Borehole Water Storage

Borehole water is slightly trickier than normal rain or municipal water, as there are quite a few things that can contaminate the ground water (for example pesticides in an agricultural area, heavy metals in a mining area, E.coli in areas where there are no sewage services), and it is vital to first test the water to identify what those contaminants are to ensure you choose the right filter for your water source. Once you have tested your water (which we also advise you do every six months or so) for a detailed list of all the contaminants our Disruptor filter range removes, click here.

Limescale is a chalky deposit consisting mainly of calcium carbonate (CaCO3), which often builds up in appliances that use hot water. This is often referred to as “hard water”. The concern around hard water is really an aesthetic one, not so much a health issue, and appliances don’t love it! Our Disruptor range is very good at removing pathogens and bacteria, but does not remove any of the minerals as part of the filtering process and thus will not remove limescale from the water. We do, however, have a Corrosion and Scale Inhibitor in our range that conditions the water by changing the composition in order to prevent scaling from building up in your pipes and fixtures.

Yes, you do require a water tank in between the supply from the borehole to your house. Borehole pumps are made to start, pump water over a distance for a period of time, and then switch off. They are not designed for switching on and off constantly for short periods of time and if used in this manner could result in the pump burning out eventually. We advise that you use a borehole pump to pump the water from your borehole to your tank for temporary storage, and then pump the water from your tank to your house with a pressure pump that has been designed to do just that.

A variable speed drive (VSD) pump is ideal as it kicks in slowly and adjusts the speed at which it runs according to your pressure requirements. This ensures minimal energy is being used while providing you with a constant pressure supply. You can view our range of VSD pumps on our here for more detailed information.
