I plumbed my lines to and from the tank, kept the isolation valves closed, but when I added check valve 'D' in the diagram at the well pump, it's messing with my CSV, the check valves are fighting each other?
I loosen the screw on the CSV open my laundry sink, pressure switch kicks the pump on and it wouldn't maintain my 30psi, just shot right up to 42psi and kicked the pump off, and I got a rapid cycle warning.
Loosened the CSV adjustment, repeat, pump kicks in at 25psi and CSV holds, I turn the CSV ever so slightly to try and maintain 30psi, holds 30psi but slowly starts creeping towards 40psi.
turn the tap off, and the tank fills very quickly not 1gpm.
I don't want to waste water by messing with it constantly, so ill wait for something to use water.
Could the check valve be causing this?
Edit. After some adjustment it seems to be fine, got my wife to shower and I adjusted, I should have let the CSV longer to react after fine adjustment, I bumped the cut off to 45psi, and got the valve to hold 35psi during the shower, and cut in is still the same at 25psi, air tank pressure is 23psi.
