Need help diagnosing a water pressure problem. In March I installed a dual canister system linked to a water pressure regulator (see photos). Starting about a week ago I found water on the floor of the basement storage area. I traced it to the connection at the valve that sends the water to either the coach or the fresh water tank. I made that repair.
Then I found water again. I noticed the water regulator gauge was showing 100 psi. Using a test gauge I checked the city water connection. It showed 75 psi. I have the regulator set to 57 psi. To check the regulator I put an old Camco restricter (50-55 psi) at the city connection. After about 4 hours the regulator was again showing about 85 psi. I found water leaking from the impeller of the water pump.
At this point I'm lost as to what to do next. I don't understand how a restricter would allow the increased pressure. I've ordered a new regulator. Should I also replace the water pump? I'm looking for ideas to try before spending more $$$. Thanks
