Water Heater Leak

[Brent10]

I have a 2013 Flying Cloud (25') and the small white hose hooking two fittings together is leaking. I have tightened it as much as I dare to without breaking something but it still leaks when I use the hot water. It is under warranty but I hate to have to drag it to a dealer unless I have to....anyone else have this problem?

I suspect those fittings are pretty generic, not an Airstream-specific product. I understand that Greer is pretty isolated, so no dealer nearby. Join the club; so is Angel Fire! If you don't have an generic RV supply nearby, try the hardware store.

A plumbing leak is a common problem when turning on the water heater and excess pressure builds up if there is nothing to absorb the expansion of the water from heating.

The plumbing system is designed to have an air "bubble" in the top of the water heater to take up this thermal expansion. This air bubble can be lost from air forced or let out of the temperature/pressure relief valve on the water heater, or simply absorbed by the water over time.

You need to restore the air in the top of the water heater if it has been lost. Try this first, it's often enough to cure various plumbing leaks caused by excess pressure. The article is from Airstream and was published by WBCCI in their magazine. Very simple procedure.

I had a similar leak in the same hose you're describing in our Flying Cloud. One of the problems was that the hose was too short, putting excess strain on the hose where the crimp is, and I think the hose was defective as well and had a poor crimp. Anyway, replaced it with the generic sink connectors that you can find at most any hardware store. Went with a longer length to take some strain off the connections; have not had a problem since then.
