Do not install a non-return valve, or devices

which contain non-return valves, in the

suction (inlet) pipework to the pump. The

pump must be free to vent to the supply

tanks at all times.

It must be ensured that the water storage capacity is sufficient to meet the flow rates

required by the pump and any other water using fittings and appliances, which may be
operated simultaneously.

As a rule of thumb: assuming a cold water temperature of 10°C and a hot water

temperature of 65°C.

A 6-minute shower using 10 litres/min will consume 40 litres of hot water and 20 litres

of cold. This means the total quantity of water used from the cold water storage tank

will be 60 litres (40 + 20).

A 10-minute shower using 15 litres/min will consume 100 litres of hot water and 50

litres of cold. This means the total quantity of water used from the cold water storage

tank will be 150 litres (100 + 50).

On installations where there are high flow requirements e.g. multiple showers or body

jets.

A 10-minute shower using 45 litres/min will consume 300 litres of hot water and 150

litres of cold. This means the total quantity of water used from the cold water storage

tank will be 450 litres (300 + 150).

The pipework feeds to the storage tank should be of adequate size to ensure

replenishment rate of tanks is sufficient to meet the needs of the pump.

Care should be taken in the design of pipework runs, to minimize the risk of airlocks.
To prevent loss of water pressure through pipework use 28 mm suction pipework to the

pump.

Any bend requirements should be achieved by hand drawing the tube or by use of the

appropriate bend fittings. All pipework should be securely clipped.

Isolating valves (not supplied) should be fitted on the suction and delivery pipework to

enable easy isolation and access to the pump.

The 1 “ inline strainer as supplied should be fitted in the suction line to the pump

between the isolating valve and the pump. This will eliminate the risk of debris or scale
entering the pump.
