Fresh water tank filling when hooked up to city water

Your Andersen valve may have some rubber washer missing or out of place. You can remove it and see if they’re intact. I never turn the valve when it’s under pressure, that can cause washers to get displaced. Or a bad check valve in the water pump could cause that. On mine it was the Anderson valve. I replaced it and that stopped my tank filling up!

You didn't mention what trailer you have, so we don't know if you have a 4-Way Anderson Valve. But in any case, we've got an owner-written Fresh Tank Fills by Itself user guide that explains what's happening, how to determine the failing component, and how to correct the problem.

Had the same problem and it was a bad Anderson valve. I was able to purchase just the inner cartridge and after a 5 minute replacement--problem solved. Replacement parts came with instruction sheet.

Easy way to fix this is to put a check valve in front of the water pump...
I had to do this on my Prowler earlier this year and solved the problem!
I opted for the Camco brass check valve instead of the plastic cheapies from other sources.
Under $10 at Camping World, although I had to pay the premium $13 in Elephant Butte, NM
Took less than five minutes and no tools to install!

My turn to report the same problem. Thanks to all you prior posters I ordered the replacement valve, $35.
I suspect my dealer would cover this repair under warranty but this is both quicker and easier.

Save the old valve for future replacement parts

Oh yeah, this cheapskate plans on doing that.

Jumping back in to this discussion (while seeking to be prepared for another common issue) has anyone got a part number (and/or source) for a quality in-line check valve?
Assuming this is a fairly cheap item I'd prefer to have one on hand (and then hope that I can find it once necessary).
