Water leak only when connected and using city water..

What ever do not remove valve caps in the wet bay!!
The vales will pop out they have o rings etc on them and when you put
the vales back in you have to pressure fit the turn cap on in order
to keep vales together. How I know is I had city water check valve go
bad and not knowing what I was doing took every thing apart!!
Got it all back together and working but was sure frustrated.
