I’ve not ever yet used PEX. In fact I know it is primarily used in radiant hot water floor systems but that’s really all I know about it. I keep saying “some day I need to learn more about it” and that some day is here.
Having just bought a log home in the mtns of TN I came to find that down there they build their homes with very little copper for their water supplies. They mostly will copper stub out close to the water supply and then from there use PEX throughout the whole house, including inside walls, joists, etc. , at least that is what I saw in the variety of homes I looked at buying. I’ll be traveling down there now to do renovations of which plumbing will be a part.
I’d love for someone to share with me all they know about PEX as for use in a potable water system. For example, some of the questions I have are…how do you connect it to a copper water line? It’s flexible and may be bent? How do you attach valves (shutoffs)? Is there any gluing involved? How do you make splices? In general how are connections made from PEX to PEX and from PEX to copper, to CPVC, etc, etc. Plus other questions I’m sure to think of later like would it be considered superior to copper or considered the “cheap shot” way to do a job?
If someone knows a lot about PEX please reply and just give me a braindump and educate me on everything you know. Don’t leave out minor details either, just wanna learn alll there is to know about it. Also what applications is PEX NOT a good solution?
