Shurflo 4008 Check Valve & Strainer
I have the cycling and sometimes filling the FW tank when hooked to city water. So I am pretty sure it's the check valve. I will be installing a check valve in the line at the pump inlet, (between the FW tank and the pump). Looking for recommendations on the check valve to get. Should I get a spring one, one with a ball, just not sure. Also do I need to find one at a certain pressure. Want to be sure the pump can pull thru it, when drawing in water.
Also, can anyone provide instructions or a guide on cleaning the strainer.
My pump is a Shurflo 4008
