Was it PEX in 1997 or some other material?
I have a 97 vectra by Winnebago, and all of the my water lines are the grey plastic line with the stripe to indicate hot or cold (Red or blue), the fittings are the threaded style that require no tools and are designed to be twisted by hand to take the plumbing apart. Each threaded fitting has a rubber tube ferrel that seals the connection without the need for thread tape. I would love to change much of it out to modern crimp pex but I dont want to take the walls apart.
My issue is the gold shower head stem pipe that goes into the wall, it is leaking into the wall and that rubber Ferrel has been twisted and I need a new one. I would change it out to another type of connector but I would need to take the wall apart to do that since it uses a "Drop ear" connector that is screwed to the framing inside the wall.
Any thoughts on what that type of plumbing was called so I can look for parts? Was it mobile home technology?
