Post subject:  Non-return valves
Manya, was i you that mentioned a non return valve.

My little submersible pump isn't cutting it any more, i have had a swimming pool pump sitting on the front door step for about 12 months that i'm thinging of hooking up. Way over powered, but i can divert 3/4 of the flow back to the tank for now.

Problem is that i can't take off from the tank below water level as its buried. Is there a one way / non return valve that is "high flow" that i can put in the suction line (theres the fridgie terms :)) That way i could prime the pump from the filter basket and it will stay primed when it shuts off

Yes / No ?

Goes on the end of the suction hose in the tank.

The non return valve will keep your pump primed.
