So I swapped out the spring check valve for a swing a check valve in the best I get is that the swing check valve cycles through a couple of times but ultimately stays open. I have the swing check valve closest to the water source and before the pressure tube, is this correct or does it need to be after the pressure tube?
Thanks H,I ordered a swing check valve yesterday and have the spring boxed up to return. Will update when I it installed, thanks for the direction.
