In summary, a booster pump is used in a pipe system to increase water pressure. A non-return valve is necessary at the pump outlet to prevent backflow into the Accumulator, which should be positioned after the pump. It is also recommended to have a manual dump/drain/sample valve between the check valve and the accumulator for maintenance purposes.

Hey,

Just something i wanted to confirm, in a pipe system a booster pump is used to boost the water pressure. A accumaltor is postioned after the pump, a non return valve is required at the pump outlet. I believe the non return valve should be before the accumaltor but after the pump.

Is this correct.

Cheers

Yup. To prevent the Accumulator from backflowing through the pump. Also note (I don't know what you may be using this for) you'll want a manual dump/drain/sample valve between the check (non-return) valve and the accumulator to relieve the system of energy for maintenance or repair of the circuit.
 

What is a non return valve and why is it important?

A non return valve, also known as a check valve, is a type of valve that only allows fluid to flow in one direction. It is important in a booster pump system because it prevents backflow or reverse flow of water, ensuring that the pump is always pushing water in the desired direction.

Where is the best location for a non return valve in a booster pump system?

The best location for a non return valve in a booster pump system is directly after the pump and before the accumulator. This ensures that the pump is protected from any potential backflow or pressure surges from the accumulator.

What is the purpose of a non return valve in relation to an accumulator?

The purpose of a non return valve in relation to an accumulator is to prevent water from flowing back into the pump or the water source. This allows the accumulator to maintain its pressure and provide a consistent flow of water to the system.

Can a non return valve be installed in any orientation?

No, a non return valve must be installed in the correct orientation to function properly. The direction of flow must be indicated on the valve and should be installed with the arrow pointing in the direction of the desired flow.

How often should a non return valve be inspected and maintained?

A non return valve should be inspected and maintained regularly, at least once a year, to ensure it is functioning properly. Any signs of wear or damage should be addressed immediately to prevent potential failure of the valve.
