City Water Tank Bypass Issue
I stopped for a night at a campground. Hooked up water and electric and the next morning my fresh holding tank was overflowing.. I have one of those cheap pressure valves. I have yet to try it again...

The pump normally prevents water from being pushed through it into the tank but sometimes a piece of debris can stick in it and cause it to leak. Using the pump may have already cured your issue. If not you may have to take apart the pump head and clean it. Worst case you need a pump rebuild kit, new pump or install an extra check valve after the pump output.
