Water System Leak

We have a water leak in the fresh water system of our Berk from the fresh water tank or city connection the bay was dripping with water. after troubleshooting I discovered the pump(shurflo smart sensor 5.7 model 5900-0201) was leaking at the seam. Did you know all water flows through the pump even when connected to city water? When I replace the pump I'm putting in a bypass valve incase I have this problem again I'm getting parts to bypass it now and will replace it when I get home in a few days. I'll try to take some pictures before and after later today.

Good idea. The bypass valve.

I'm thinking there must be check valve somewhere. I know there is some valving in the pump. I not sure how it flows to the pump but it does.

I believe the water from the city hook up pressurized all of the lines including the line to the output of the pump. The input obviously comes from the tank unless bypassed when winterizing. So it makes sense that the pressure would run through the pump to the flow switch at the input side of the pump. Never really thought of it though! Good idea on the bypass after the output of the pump. Other option is just cap the line from the output of the pump when not using the pump.

I'm curious, what PSI are the water pipes in the Berk rated for?

I remember seeing somewhere that FR tested the pipes at 85 psi.

I've always have run a regulator set to 45lbs. Apparently there is a check valve inside the pump and that is what failed no parts available and the pump has been discontinued so I bought a Remco aquajet 5.3 and installed it.

That's a nice replacement pump accumack! 60-75 PSI @ .7GPM is pretty powerful. It does draw power though - 10AMPS @ load; is it on a seperate breaker?

Tom, thanks for the info. our Rockwood can handle 65PSI - I have a variable pressure regulator and DO like a residential-quality shower

Thought of changing mine to this Flojet V-Flo Constant Pressure Pump, 5 GPM - Xylem R4426143A - Fresh Water Pumps - Camping World

Do you guys think that this is overkill?
