City water inlet leaking on inside

[openroad118]

I'm boondocking and went through a freeze a few days ago. When I got to Death Valley, I noticed the dump valve plumbing was wet with water coming from above. RV is a 2013 fc 20'. Today I removed some sheet metal next to the toilet and, using a remote camera, I could see a small drip coming from the backside of the city water inlet.
I could remove the bathroom sink counter top to get to it but will any RV dealer have a replacement for the guts of it or do I have to go to Airstream dealer?
I see some screws holding the casing halves together with perhaps a gasket in between, so tighting may solve it.
Any input on this unit whatsoever would be greatly appreciated.
Thanks

I've been through a few of them that started to leak. Not the highest quality item but available from Amazon for pretty cheap. I now just carry a spare. I do wonder if we get too high of water pressure at a campground it causes them to fail.

The 20-footer thread has a number of posts with photos for that general area, including the anti-siphon vacuum breaker for the black water flush system. Your 2013 FC20 plumbing layout may be different, but posts from CruizinDux, TCwheels, and our 2014 may help guide the way. If you have the old plastic vacuum breaker, you might consider replacing it if you have to open things up.

Ditto to HeadWest that the city water inlet is probably a fairly generic one, and ditto to get a spare IMO.

The later posts in that thread should help out with visuals, and links to earlier posts with photos.

Also, this 4/1/17 Post #1604 from TCwheels shows his dinette removed, and other nearby posts go into more detail etc.:

Also -- vacuum breaker info which will lead to another thread and posts with photos, I think:

Running out of edit time here, so hopefully the info above will help. Will check in later.

Good luck!

I was able to remove the unit from outside and very slightly tighten down the four screws that hold it together. Maybe this will help but I will look for this unit at my next stop which maybe Yuma Arizona. This was great help thank you

That is how a 23 owner addressed his similar problem when working on the Grand Canyon North Rim. The permanent solution is a straight through city water port, an internal adjustable pressure reguator and an expansion tank. Pat

openroad118, Pat's(PKI), is faster than Wyatt Earp. I remembered the thread (as I figured I'd be there or at the BW back flo some day too) and that he had commented (always helpful & informative)...lots of open range land for that search...but finally...wish had remembered the GC reference.

Let us know how this works out if you have to replace.

happy trails

We had a similar issues on our 28' FC. It was simple to fix from the outside (after worrying for 3 days i was going to have to remove furniture). I took off the 4 screws and pulled it out just enough to tighten the threaded pipe fitting. That was all it took and it's been good for the last 6 months. I did put new sealant around the flange when i tightened it back up.

Pragnar2, is this aftermarket as opposed to AS oem?

The city water valve is a staple item at all RV parts stores. On my Classic, if you take the the input valve/pressure regulator and water faucet out as a whole it is a lot easier to work on in the cramped compartment. My city intake had frozen enough to separate the halves enough for them to leak. it is a good idea to tighten all the fittings before reassembly. Be sure and blow out the city inlet with compressed air with the faucet valve open to expel any water left in line when you winterize. When I blow my system I have already disconnected the water pump outlet so that is where I let that part of the plumbing drain.

As guskmg says, the fitting can leak between the two yellow plastic pieces. I remember seeing at least one other thread here where someone fixed their leak by tightening the four screws on the back of the fixture.

Mine leaked this way, and I replaced before I realized there was a possibility of fixing it with those screws. After I installed the new one, I went back in and snugged up the screws. I hope that postpones my next leak.

Sometimes the unit can be fixed by tightening those four screws on the back. In my case that did not fix the leak so I ordered a new unit from Amazon and it took about 10 minutes to replace.

When replacing what is the recommended sealant between outlet and aluminum ?

In theory, there is a gasket there, so you shouldn't need anything else. In practice, I'd run a bead of your favorite sealant around the perimeter. I like sikaflex 221.

Thanks - appreciate the input

Easy fix. I had the same leak hitting the waste valves. Order a new ShurFlo regulator. Mine was a 183-29. You can look on the outside of the city water inlet and see the label.
When u get the regulator, just remove the 4 screws pull the regulator out and disconnect the water line fitting.
I removed the neoprene gasket very carefully and reinstalled it in the new regulator.
While I waited for the new regulator to arrive by mail,
I removed the 4 screws of the regulator and pulled the regulator out of the wall to allow it to leak outside the Airstream.

I have done the same thing. You should be able to get it removed from the outside. I used a hair dryer to dry the insulation. Retightening it lasted a week until a new one came in and I retirqued those screws before install
