Pipe material 1996 December 08, 2020, 12:39:28 pm Does anyone here know what the water piping is in a 1996 ? It looks to have PEX compression connections, but the gray color makes me wonder if it’s the old Polybutylene.
Re: Pipe material 1996 Reply #1 – December 08, 2020, 03:05:16 pm Our 1997-8 mid-bath had (what I believe to have been) polybutylene tubing. I used polybutylene-to-PEX adapter fittings where needed.Mark H.
Re: Pipe material 1996 Reply #2 – December 09, 2020, 01:48:59 am Our '83 had the polybutylene tubing with grey plastic flare connectors. I might have had an instance once of a kinked tube, but every failure I had was with the plastic connectors, and most did fail. I replaced all with brass flares, and never had a failure since of any sort. I don't know if crimp connections are kosher, but if there are no leaks...Steve
Re: Pipe material 1996 Reply #3 – December 09, 2020, 11:52:52 am mine is a 1995, and has polybutylene pipes which I think I read somewhere that they were phased out in 1996, however that takes time, also the RV takes a year to make so a 1996 rv would have materials that were considered ok in 1995.Check the pipe markings, if it says PB2110 it's polybutylene. It's no big deal if you don't have leaks, but definitely more prone to leaks.If you plan on replacing any of it, they make transition joints to pex which work great.
Re: Pipe material 1996 Reply #4 – December 09, 2020, 06:01:45 pm Thanks all. I couldn’t get anything in position to read the spec on the pipe. I found that some OEM used crimp rings like PEX, the copper rings, as on mine, seem to be superior to aluminum rings.

I personally have a leak on the hot pipe in the bathroom sink, but only when I use it with hot water, so something must expand I guess. Not as big of an issue for me to change that whole line yet though.... 1 Likes
