Fresh Water System Leakage

[Bill_Carry]

I'm experiencing leakage out of the fresh water inlet. I assume there is a check valve in the system to prevent backflow from the water tank to the inlet, perhaps in the pump. Its a SureFlo pump, at least ten years old. For the time being I cap off the inlet when not hooked up and that works.

Thanks for any advice.

A few years ago, we had the pump suddenly start cycling on its on in the middle of a 3 week trip. I tracked it down to the shore water inlet check valve letting water out. At least all of the leaked water was OUTSIDE of the RV. I bought a garden hose shut off valve and screwed it to the shore water inlet and closed the valve. That solved the problem until I could get home. When at home, I replaced the check valve.

The check valve is inside the fresh water connection. I believe it is about $15 or so.

These posts are common in the spring because people damage the check valve when winterizing.

If capping the "city water inlet" stops the pump from cycling, then the check valve in the inlet is bad. Replacements of the inlet and valve unit is readily available. You remove the inlet from the outside, but the hose may be difficult to get to depending on the slack they gave you.
