Well booster pump replacment
I needed to replace my Goulds 2HP booster pump. Turns out the new pumps no longer include a check valve. Replaced the pump, upgraded unions and piping and added Cycle Stop Valve, high pressure booster switch and 10 gallon tank kit. I can now maintain 75 PSI at 4BR, 4 bathroom house with 25GPM and run irrigation system at the same time.

Leaking after 4 months
This valve looked fine when it was installed.Installed this to replace a valve after twenty years of use. This one is leaking back flow after 4 months.
