brass valve

The brass valve is a water drain for the plumbing system, not the tank. The white valve drains the tank. I broke the brass valve while my trailer was sitting in my shop trying to figure out what is was for. Had a hose hooked up to the water supply and turned the valve. 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.

Brass waster drain Mod i made. Had problems w/plastic valve. So,removed some rivets in corner of tank cover. Peeled back cover just enough to removed plastic valve and connected hose to fitting on tank ,ran it thru previous valve hole. Ran it to mounting plate of Black/Grey Drain valves. Mounted brass ball valve to plate and hose to valve. Re-riveted cover over tank. Now the fresh water is next to Blk/Gry valves. Don't have to get under trailer. Very nice. One of best mods i made.

Nothing in the owners manual about the brass. Dealer doesn't know anything.

FWIW I would at least tighten that valve by 1/2 turn and get the handle to the side instead of on the bottom. You gain an inch of clearance that way.

Could you put a little water in the tank and confirm this, or are you already fully winterized? My 2014 owners manual has a paragraph on draining the FC23's water tank, but does not mention the brass valve either.

Who is your dealer? I would be amazed if an Airstream dealer did not know what this valve is for. If you purchased from a dealer that has all sorts of trailers, I wouldn't be surprised.

Take it to Spokane Airstream and have them look at it. If the Spokane dealer told you this I would be beyond amazed. Please post and let us know who told you that.

Mike,

I'm going to try and change it out with a smaller valve that allows more ground clearance. Your right about it being tight in there. Not sure I can swap it without cutting a hole to hold onto the hose.

Thanks

Did you figure out what that valve drains? If it's a repetitive winterizing thing ..... maybe an access port is good. Depending on what it drains, access inside and space ...... Try an interior ( better for cold outside anyway) vertical orientation of the valve for the vertical low point drain. Much improved clearance and no cold knees.

Does everyone agree that the brass valve is a propane-style fitting to accept flared tubing on the left end? Why was this fitting used at all, especially without having it described in the owners manual? Seems like a real afterthought IMO, brought on by a problem in some models with water getting trapped at a low point between the fresh water tank and the pump. Did they just happen to have a bunch of spare propane valves on hand the day it was added to the production of this coach? What other models have it, and has Airstream notified those owners?

Not exactly a reassuring situation re: quality control IMO.

In scale, the threaded portion of the valve at the left looks like 1/4" NPT. Don't see a flare end.

The left end looks bulbous to me like a flare fitting. I have taken a zoomed in screen shot of just the valve, but I am still not able to attach photos as discussed in the thread linked below.

111, could you please give us an opinion on whether the left end of the brass valve in your photo is convex to receive a flared LP gas line, or not. Thank you.
