City Water Connection

We have a 2017 16 Scamp. I was working to dewinterize by adding fresh water into the onboard tank and when I turned on the 12 volt demand pump I had water being forced out the city water connection. I worked with it for about an hour by cutting the pump, moving the inside spring around, and re-pressurizing the system. I finally got the city water connection down to a slow drip but never completely sealed.

Wondering what I did wrong ............ when I winterized last fall I used the fresh water tank and onboard pump to circulate the RV antifreeze. The last step was pushing "in" the city water connection to relieve pressure on the lines. It then went the winter.

On the plus side I have found no internal leaks so at least my efforts to winterize were successful.

Has anyone else had a problem with the city water connection? Perhaps the rubber dried out inside?? Hate to think I need to drill rivets and replace the city water connection just outside of warranty.

Sounds like you did the right things to try and get the check valve working. Also hook up to shore water and run some water for a while.. maybe that will dislodge some debris that is not allowing the check valve to close.

As for replacing it.. might be needed.

This is what I did in a similar situation:

How I replaced my city water inlet and added a shutoff valve

I'll never have to worry about the check valve in the city water connection leaking ever again.
