Keystone RV Forums - View Single Post - Water valve - city to fresh tank fill

Thank again for all the help!

I disconnected the fresh tank fill line from the diverter and plugged the lines. The fresh tank continued to fill. "dirty rotten sheep herdin'" er..um.. I mean...

It turns out the problem was a check valve in the pump itself. ?? I didn't even consider that option possible. hmmm. I disconnected the output line running from the pump to the camper and capped that line. I also reconnected the city or fresh tank line to the diverter. The fresh tank does not fill up any longer.

Of course, I no longer have instant access to the fresh tank water supply, either. So, I am working to find a shut-off valve to connect to the pump output side. The pump still works great so why replace it.
