City Water / Tank fill valve

[arby]

My valve has developed an internal leak.............ie..........when in the city water position it slowly fills the tank. Looks like a major job to get to it. Anyone with experience on this? 07 Diplomat PDQ

Before you do that check no more thing, it's a long shot but it's easy to do. Remove the handle and check where it attaches to the valve stem. It may be slipping on the valve stem not allowing the valve to fully close. Also try to operate the valve with a pair of pliers being very careful not to strip the soft brass stem. If that doesn't work, it's time to change the valve.

You, need to be sure it's the fill valve and not the 12 volt water pump, internal leakage in the pump will do the same thing.

arby,

I have had mine off twice, not because there was anything wrong with it but because it has to be removed to take off the white panel. If yours is like mine there is a black panel in the upper right corner above the valve. take off the handle on the valve. Take off that panel and reach in behind the valve and feel for the two water connections. You can use your hand to turn the nuts removing each water line. Now remove the screws holding the valve to the white panel. It takes some work but you can maneuver the valve out from the back and out the opening where the panel was removed.

Thanks for all of the replies and help.

RJay, you were right on. If I take the handle loose and turn slightly past the normal "stop" the leak stops. There is a nut behind the handle. I wonder if I can loosen it and make some adjustment? The handle is not slipping on the shaft.

I turned the valve 360 both ways several times. I thought maybe there was some debris lodged in there causing the problem but it didn't help. Suggestions?

Nodine, I took that black panel off. I can see where it is possible to change the valve without taking that big white panel out which looks like a horrible job.

And idea where to get the exact replacement for the valve?

Thanks again for all the help.

Problem solved. Had to buy a new valve from Monaco for a mere $129 !!! Spent about half that in gas running all around Houston looking for one. The bottom fitting on the new valve was installed 90 degrees off and was really locked in there with pipe dope. Took two big wrenches and two of us to move it but after that it was a 5 minute job.

It may look like a major job however let me tell you what I found on my rig when I had to plumb near there (One of the lines hooked to it in fact)

I pulled a few screws, Unhooked a pair of color coded quick disconnects and the entire panel came out to the picnic table where I had all outdoors to work on it.

Standard 1/2 inch IPT fittings, even if they are plastic No special tools or skills needed.

Yours may be easier or harder depending.

Oh, and the valve is a standard hardware valve in most cases... No need for special RV types. Though in some cases... I don't know And the handle may be different at the hardware, or the mounting.

Damon may have had a better idea but there is nothing "standard" about this valve. Home Depot and Lowes have many different "ball cock" valves but none that have 3 hose fittings. Was well worth the 129 bucks to me to let Monaco and UPS deal with the frustration of getting the correct part to me.
