Question City Water Connection Leaking Into Fresh Water Tank(?)

The only thing wrong with the pump is it's an RV part! I told you how to fix it permanently. All you have to do is listen and go to the hardware store!

I heard you.

First, I don't have time for a major re-engineering of the trailer's water system, as we are leaving on a camping trip in about 30 minutes.

Second, the pump seems to work fine except for the check valve. I want to investigate the nature of the problem, and try fixing it there first.

Thanks for the suggestions.

I also had that same problem. Decided after reading about fresh water tank filling when hooked to city water, that I was done wasting my time and getting frustrated. Time was more important so I just replaced the pump. Problem solved. I also put in a little bit larger pump capacity. Better water pressure when using the pump.
Also, you should never have the pump running when connected to city water. Or so I have been told by repair tech.

That is certainly not exactly true. I have been at campgrounds with very poor water pressure where running the pump made things much better.
