Flair-it Valve Repair

[Jim A]

On our recent trip I had a problem with the water tank fill valve. It failed and essentially stayed half open. If I had used the city water it would slowly fill and then overflow the tank. If I used the pump instead, it would recirculate the water to the tank, never building up enough pressure to shut off.

You can replace the valve stem and seal, which will likely be easier and definitely cheaper than replacing the valve. The PEX tubing is hard to remove from the fitting, and if you cut the tubing it can lead to length issues. The stem and seal is easy to remove and replace. The stem and seal are ~$3. It looks like the same stem and seal is used in a lot of the Flair-it valves. I will definitely carry spares from now on just in case.

If you ever need them, here are the part numbers:

Stem 06441
Seal 06419

Jim;

While I have never had the problem you have experienced I did have to replace a shower valve that used Pex tubing and Flair-it fittings. I learned that my wife's hair dryer heated up the tubing hot enough to remove the tubing from the fitting. Good luck.

Mine's fixed. The new stem and seal did the trick. Fastest and cheapest fix on the coach to date!
