Just in case anyone else had the same issue with the shower hose leaking at the point it connects to the fixture that is attached to the tub.
the part is alsons vacum braker #A900 Ace has it for about $14.00 I spoke to a fellow Airstreamer late last night on the Chat room and he suggested I go to Lowes again. I found a similar washer but larger but same hole size in the middle. I trimmed it down and it works great! and Only 92 cents.

Hello everyone!

I have what I thought was a simple question, but I called Airstream then drove 70 miles to the only Airstream dealership in our area. I got the deer with the headlight look to my question from both. I really hope you all can help.

My shower in the 1999 Bambi has the shower hose that attaches to something that I don't know the name to. a baffle or washer of some kind wore out and now water shoots out from where the hose attaches to the piece that attaches...
