1. Base / concrete plinth 

Ensure tank is installed on a suitable base. The base must be sound, level, smooth, free of any protrusions and at least 100mm wider than the base of the tank (refer to pre-installation).

2. Plumbing – tank to pump

Use minimum of 25mm diameter pipe from the tank, to the gate valve, to the pump. Connect the pump to the electrical main supply.

3. Plumbing – pump to house

a. Use minimum 20mm pipe from pump to cut into mains (where possible), before the PRV valve.
b. Install a non-return valve (between house and mains) to ensure no back pressure to mains.
It is recommended that the foundation should be at least 100mm wider than diameter of tank.

4. Supply tank with water

Supply the tank with municipal feed to float valve at the top of the tank. When full, the float valve will close the water supply and when it drops it will open and allow the tank to be filled.

5. Fill the tank

Ensure that the gate valve is open and fill the tank from municipal supply.

6. Recommendation

It is recommended that the water is run once every two weeks to rotate the water and ensure system functions properly.
