The faucet has an interal leak that is running down inside the faucet into the access cabinet below. I haven't had any luck with Airstream getting a repair kit (like you can do for your home faucets) or even a replacement faucet.
Does anyone know the manufacturer of the faucet or have a source for parts or an RV supplier with a similar faucet that I can buy?
Chances are it's a Moen faucet, (supplier to AS). You'll need to take out the cartridge and send them a photograph to see if in fact it's their part. I've found Moen to be a very good company that will respond quickly.
