CORRECT TANK INSTALLATION

PREPARATION

SELECTING YOUR TANK

Municipal Back up System Installation

Here is a step-by-step guide for setting up a water tank system connected to the municipal inline water feed, incorporating a float valve, suction hose, pump, and optional components like a three-stage filter and UV light:

Step 1: Prepare the Ground Base

Ensure the area where the RotoTank will be placed is level and solid.
Build a stable concrete base to support the full weight of the tank when filled with water.
Ensure the base is flat and level with no protrusions that can damage the underside of the tank.

Step 2: Install the Water Tank

Place the RotoTank on the solid base.
Position it near the incoming municipal water feed to ensure ease of connection.

Step 3: Install the Float Valve

Install a float valve inside the water tank. This valve will regulate the amount of water that enters the tank from the municipal supply, ensuring the tank fills up but does not overflow.
Connect the municipal inline water feed to the float valve, ensuring the connection is secure and free of leaks.

Step 4: Attach the Suction Hose

Connect the suction hose to the bottom outlet of the tank. The suction hose will carry water from the tank to the pump.
Use a flexible pipe at the connection point to the pump. This will help absorb vibrations and reduce noise from the pump operation.

Step 5: Install the Pump

Install the pump next to the water tank. Ensure it is positioned on a stable surface.
Connect the suction hose from the tank to the inlet side of the pump.

Step 6: Connect the Pump to the House

From the pump, the water can be directed either into a hose (optional) or into a three-stage filter system (optional).
Hose Option: Connect a hose directly to the pump for outdoor water use.

Filter System Option: For filtered water supply into the house, connect a three-stage filter system to the pump outlet. The three-stage filter will help remove contaminants and purify the water.

Step 7: Install the Three-Stage Filter System (Optional)

The three-stage filter system should be mounted securely on a nearby wall or structure.
Connect the pump’s outlet to the first stage of the filter system.
Ensure each filter is properly installed and the system is ready to filter water before entering the house.

Step 8: Optional UV Light Installation

For additional water purification, install a UV light system inside the tank or at the outlet before the water enters the house.

The UV light will kill germs and bacteria in the water, providing safer drinking water.

Step 9: Final Connections

After the filtration system, connect to the buildings water inlet.
Ensure all pipes and fittings are securely connected and leak-free.

Step 10: System Expansion

This system is modular, allowing you to start with the basic setup (municipal feed, tank, pump) three-stage filter system, or UV light can be added at any time, additional tanks can also be added

Step 11: Final Checks

Inspect the entire system for leaks and secure connections.
Test the float valve to ensure it regulates water levels in the tank.
Run the pump to ensure it transfers water effectively from the tank to the house or other uses.

This setup ensures a stable water supply with options for filtering and purification, customizable based on your needs.

Rain Water Harvesting Installation

Here’s a step-by-step installation guide for the RotoTank Rainwater Harvesting Setup with Gutter Buddy and First Flush System.

Step 1: Prepare the Ground Base

Ensure the area where the water tank will be installed is level and solid.
Build a solid, concrete base to provide a stable foundation for the tank. The base must support the full weight of the water tank when filled with water.

Step 2: Install the Water Tank

Place the RotoTank on the solid level base.
Ensure that the tank is positioned close to the downpipe system to allow proper connection.

Step 3: Attach the Gutter Buddy

Fit the Gutter Buddy to the top end of your roof’s gutter system.
The Gutter Buddy will prevent large debris like leaves from entering the rainwater harvesting system, ensuring cleaner water flows into the tank.

Step 4: Install the First Flush System

Install the First Flush Diverter underneath the gutter downpipe.
Use a recommended length of PVC pipe (650 mm x 110 mm) between the downpipe and the diverter.
The First Flush Diverter will capture the initial contaminated rainwater from the roof and divert it away from the tank. This ensures that only cleaner water is sent into your water tank.

Step 5: Connect the Downpipe to the Tank

Attach the downpipe from the gutter system to the water inlet on the RotoTank.
Ensure the downpipe is securely connected so that rainwater can flow freely into the tank after passing through the Gutter Buddy and First Flush system.

Step 6: Set the Height for a Collection Bucket

Leave an appropriate height between the ground and the end of the First Flush pipe for a bucket or another drainage mechanism to collect diverted water.
Make sure the system is properly sealed and positioned.

Step 7: Final Checks

Inspect the entire setup to ensure there are no leaks or loose fittings.
Check that the Gutter Buddy and First Flush System are correctly filtering debris and contaminated water.
Confirm that the RotoTank is securely in place and that water flows smoothly into it during rain.

With these steps complete, your rainwater harvesting system is ready to start collecting water efficiently!

Preparation for Installing a Stand

Prepare a stand that has hardwood or steel decking with gaps no greater than 40mm. For stands not purchased from RotoTank^TM, ensure that it is manufactured according to legislative requirements if it is higher than 1.8m. For stands up to 500mm you can also purchase a plastic tank stand from RotoTank. This is a plastic ring that is filled with building rubble (or any available material), compacted in 150 mm layers with the top 50mm river sand or soft soil (no sharp rocks or objects). Decking should be supported structurally by bearers strong enough to prevent sagging of decking when tank is full. The tank can be lifted into place by crane if required (if positioning requires a crane this will be at purchaser’s expense). The tank must be secured with RotoTank cable tie downs or water filled to 55mm to prevent blow-away (no responsibility taken for tanks being damaged in this manner).

Installation Questions& Answers

When ordering your tank make sure what your installation needs are. Your local RotoTank branch keeps a wide range of accessories to connect your tank, but, for special needs you may want to consult an installer or plumber.

RotoTank’s water tanks are equipped with standard 40mm or 50mm inlet & outlet fittings dependent on the size of the tank.

Colours do not make a difference when purchasing a RotoTank water tank, all water tanks come supplied with a black inner liner to prevent Algae growth.

Make sure that the manufacturer’s recommendations are followed to prevent a warranty dispute. Rigid piping can for example crack a tank due to expansion cycles, ensure a flexi hose from tank to pump is fitted to prevent this issue. Plumbers may have other methods but your warranty could be affected if not correctly installed.

At RotoTank your friendly adviser will give you ample installation tips.

SAFETY

One often does not think that a water tank may be a dangerous item. But, consider for one moment what happens to five tons of water, or more, when a tank bursts due to poor quality. At RotoTank our quality guarantee ensures a safe tank. Our water tanks are equipped with child safety lids preventing small children from opening the lids. Our tanks are manufactured with food grade material which will in no way compromise the liquid held inside.

COVER ALL THE ANGLES

Water, water everywhere! But every drop saved from your taps, shower and washing machine counts for nothing if you have a cracked drainpipe or leaky outside tap. Therefore, make sure your water saving plans are not in vain, do a full maintenance check of all peripherals to the rainwater harvesting process. A good idea is to check your water bills regularly to make sure you’re being billed for a number of liters that roughly makes sense. If it doesn’t, investigate your property for leaks like some sort of water-saving superhero.

ADDED EXTRAS TO MAKE YOUR WATER SAFE TO DRINK

For peace of mind you can add Filters and UV lights to Clean the water and assist with preventing harmful bacteria. Additionally RotoTank supplies Nanopure tablets that can be added to the water to keep it fresh and drinkable.

GET ON WITH IT!

Well, there you have it. There’s no time like the present to do your bit and recycle every precious drop.
