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.
