Water came out and the valve broke off. The 90 fittings have a thin wall and are easy to break. It is a pita to fix, had to cut an access hole to gain access to the pex tubing. If it breaks, the brass fittings will just spin in the pex. I put a smaller valve, like that found on a car radiator, to reduce the chances of being hit, eliminating the 90 fittings. Hope this helps.

Thanks Mike for solving the mystery here. I believed you but thought it best that 111 confirm the diagnosis for HIS coach's valve.

Could you guys please comment on the left end of the valve being convex/bulbous to receive flared copper tubing, or is it NPT as wander-west suggests?

No flare on the brass, Its a low point drain for the lines but its in a exposed area. Just asking to be knocked off or turned on so all my water gets pumped out.

Great for winterizing though..

I have the same setup on my 23D. Mike S. has it right. It's a drain on the plumbing side (after the water pump). If I remember right, take out the converter/ fuse box and you can see the tube go straight down through the floor.

I am going to put on a winterizing kit this year and have everything apart......again. Can get a picture if someone needs.

Probably low point drain for water lines.
We have. 25' Flying Cloud. Had to replace one of our low point valves. Airstream sent us a brass value just like this one.
