City water issue

Hello, I have a 1993 King if the road F32MAX 5th wheel I am having a problem with. When I hook up a hose from the house to the RVs city water connection I get no water to the RV. The water is on at the house I turn on the faucet in the kitchen and the bathroom in the RV and nothing not a drop of water. I have attached a pic of the water inlet on the RV and I see what looks like a check valve could that be the problem? Any help would be appreciated.

It sounds like the check valve behind that fitting is defect and will have to be replaced.
It could also be that there is a valve in the wrong position. In this case you would hear water running like into fresh water tank.

Hope this helps.

That is a one way check valve. Just take your finger and see if you can move it around some. It might fix it. But it could be something else also. Is the hot water tank full? you may not get any water untill it fills up.

Welcome to iRV2!

The check valve is most likely your culprit.. Those city water inlets can be replaced.

Replacement may not be needed, Sometimes after a period of non-use it will stick, Simply pressing the center button will clear it (Remove screen washer, depress center button, replace screen washer and try again.

WARNING: Sometimes pressing that button will break it, but since you are already planing on replacing, no loss there.

Check with the on-board water pump on too.


On my coach is a 3-way vavle in one position (normal) it feeds city water to the "House" systems (Sinks, toilet, shower). In the other (FILL) it feeds city water to the fresh water storage tank.
Home is where I park it!
