Water coming out of city water hook up

[vegas450r]

This weekend at dumont, turned on water pump to use the bathroom. I usually just leave pump on all weekend. About 20 minutes later, i was walking around motorhome and notice water running out around door for filling up tank and city water hookup. opened door. and found water coming out of hose connection. i had lost about 1/2 tank of water. I then hooked up a hose to hook-up and put it in a water can i always bring for extra water.

I haven't had time to check it out yet, but I firgure there's got to be a check valve in the system somewere. anybody have any ideas?

Good ops,, yeah, it's propable a check or non return valve jazzed.

You may be able to call the manufacturer and they'll tell you where it is.

Mines easily accessable from the cargo storage, sometimes their right there at the tank, or at the pump.

probably a very easy DIY job.
