Problem after using city water ...

As new RV owners this was only our second trip in our Chinook, and the first time we had hooked up to city water. We used a new hose with a pressure regulator attached.

After unhooking from the city water, we find that when we turn on the water pump, water flows out through the fresh water filler.

Any ideas what would cause this?

I had filled the fresh water tank ... is it too full?

Appreciate advice. Thanks.

You have a bad check valve on the fresh water inlet side. Look into the opening of the city water hookup. You will see a little plunger in the center. Wiggle it around some to see if a rock or other debris is caught in it.

Some are made of plastic and come apart if the water pressure is to high. It would be best to replace it with a brass one made by Camco, about 10 bucks. It is an easy job, about 30 minutes. to replace.

There is a check valve in the inlet that is supposed to prevent water from flowing out when using the pump. Sometimes, this check valve will stick open or sometimes a rapid change in water pressure like you may get from a quick-turn ball valve (as opposed to a spigot where you turn the handle several times to get the water flowing) will blow the O-ring off the stem inside the check valve.

There is probably a little conical screen inside where the hose connects. The first thing I would do is pry that our and see if I could reach the stem and re-seat the valve. If that doesn't work, some check valves can be disassembled for repair, some can't. If you can't repair it, you may have to replace it.

In case it turns out not to be a bad check valve... make sure when you finished filling the fresh water tank you didn't leave open the lever which directs either city water or tank water to be used.

As a quick fix you can get a shutoff used on hoses and leave it permanently connected.
