Plumbing leak in polybutyl

[rhinzman]

Hi,

New to the forum but not to AS. Have plumbing leak in 86 excella 32'. It appears to be plumbed with polybutyl. I think that is the grey stuff. From my lurking it appears that it is not available anymore. Is that correct & if so what is best avenue. The leak is right above the tank, accessible under cabinets next to kit sink right by a valve. The valve seems to be 3/8 x 1/2 x 1/2 Leak is on the 3/8 connection. I am not interested in replacing all lines. Will appreciate any help.

Thanks,
Ralph

Welcome to the forum, Ralph.

Most people appear to use PEX nowadays. Your best course of action may be to cut out a portion of the leaky line and head down to the local home improvement store. Look for replacement plumbing of the same outside diameter.

If located, purchase two appropriate unions along with enough replacement line.

FYI There is a judgement in a class action lawsuit against the manufacturers of polybutelene lines. In homes they will pay for a plumber to come in and redo all the lines and put you up in a motel to boot. I don't know how this affects RVs. The problem was in the crimped connections. If not done right they leak. I had a house with polybutylene plumbing and never had a problem.

I called the AS dealer after I posted my question. Person in parts said they still use the stuff but with different connectors. Got on it too late today so I'll go there Mon. & pick someone's brain & check out the options.

According to a post I read earlier the lawsuit doesn't provide any relief for RV's. This is the first plumbing problem I've had & I've had it 10 yr.

Thanks.
