Re: [MBZ] OT Pex
We have the opposite problem, our water is a bit basic, I've been replacing all of our type m with the thicker stuff, type f? I figure if the original thin stuff went 40 years this should do pretty well. Our house is small, there isn't that much plumbing. I did half last summer, I'll do the rest this year.

Re: [MBZ] OT Pex
In this case, freezing temps. It is seasonal. While I have been careful about drainage, it is in blueberry country. (acid soil = acid water = copper washing away, as well as Iron pipes washing away.) THe copper is over 40 yrs old. All the pipes hung below the joists. Now all the plumbing is neatly tucked up between the joists. All the joints I redid with the permatex clear rtc are holding nicely. I redid a couple more last night without leaving the water off for a 1 hour cure time. They hold even without the cure time. Another factor was to make as many runs as possible sloped so that when the bottom manifold is drained, the pipes drain also. I will have one sink that will need to be drained separately. Making the drain process simple is a big advantage. My goal was to be able to open two valves (hot and cold manifolds) and drain the whole thing.

Re: [MBZ] OT Pex
I did not use the hose clamps. I used the apollo type pex clamps that you crimp on one side. Think fountain soda hoses. The other type is a ring that is compressed similar to a hose ferrule. I did find a cure for the threads. I took everything apart and used Permatex clear RTV as dope. Let it cure an hour, and no leaks. One of the leaking 3/4" Pex mains, I took off the hose, put the RTV on the brass fitting. put the hose on and single clamped it. It appears to be holding. I do not trust sharkbites in walls at all, unless it is a fix n flip situation where the future is someone else's problem. The oring WILL deteriorate. It is only a question of when.

Re: [MBZ] OT Pex
I did a few PEX joints and I used those copper bands that get compressed over the PEX joint by a special crimping tool like this one: https://www.amazon.com/IWISS-Crimping-Suitable-Sharkbite-Standards/dp/B0759GM5NL The tool cost more back then and the jaws were held in by set screws. Never had a leak. Also, I had better luck with Teflon tape than the liquids. I had one really bad hydraulic connection (3000 psi) that blew out the liquid seal every time but the tape did the job. > -Original Message- > From: Mercedes [mailto:mercedes-boun...@okiebenz.com] On Behalf Of > Curley McLain via Mercedes > Sent: Tuesday, July 02, 2019 1:05 PM > To: Mercedes_Discussion_List > Cc: Curley McLain <126die...@gmail.com> > Subject: [MBZ] OT Pex > > Well, I got the copper plumbing cut out and the new PEX system turned on > yesterday.

Re: [MBZ] OT Pex
What sort of fittings? Some people swear by Sharkbite, some people swear at them. I suspect the initial leaks are operator error, but I'm leery of drywalling over Sharkbite and having it weep a few years later. If I were doing it, I'd use the barbed fittings that you put a PEX tension ring over the tubing, stretch tubing and ring, then quickly stick it on the barb.
