Frequently asked questions

Where should a check valve be fitted?

On the suction line when the pump sits above the water level, to keep the pump primed; on the return line to stop the filter draining back through the pump; and downstream of a chlorinator or heater to protect them from back-flow when the pump stops.

Which size do I need?

Match the pipe: CV-50 for 50 mm pipe, CV-63 for 63 mm, CV-1.5 for 1.5 inch and CV-2 for 2 inch. The two-part body is bonded with a special cement and the transparent body lets you see the gate close and confirm any leak-back without dismantling.

Does a check valve add pressure loss?

A small one — the gate opens with the flow and sits fully open at normal circulation. Install it in the flow direction marked on the body, and never on the pump discharge with a closed valve downstream.
