I have decided to install an inline, external check valve at my pump. Can someone tell me which side it should be installed on? Thanks.

The filter is supposed to be attached to the inlet side of the pump to catch debris before it goes through the pump. I would imagine you would want the check valve on the opposite side to keep water from flowing backwards, usually there is an arrow on check valves indicating flow direction and that should point away from the pump.Scott & Mikaela

Be aware, a typical check valve will drop 2-3 psi water pressure. Not a lot, but most people value all the pressure they can get. Curious why you’re adding a check valve when the pump provides this function already. I also wonder if it might increase the pulsation in your pump output since the pressure switch will effectively now be between two check valves.2022 3100RD
