I don't think I would recommend PEX for a home install. Too much water pressure. It is perfect in an RV when coupled with a water pressure regulator. I, too, tore out the swollen copper and put in PEX although I didn't use the SharkBite fittings. I just used the regular fittings that are installed by hand with a final twist with a pliers. I had one small leak in the shower cold water feed and with another 1/2 twist on the fitting, no more leaks. This was 8 years ago and countless miles. I would do it again and probably will on another vintage trailer one day.

My only frustration with Shark Bite is that they are pricey. For 'accessible' connections I use the 'twist' connections. Around my water heater the working space is limited to just using one hand. Shark Bite saved me from removing cabinets.

Both of our sons have built new homes within the last 2 years and it was pex all the way by two different bulders. Even the baseboard hot water heat is put together with pex. Me thinks it's the way of the future. Does A really nice job too.

Sometimes it's hard to teach us old dogs new tricks, but sometimes new is better.

When we do a new job,especially above the 2nd floor,the system is pressurized to 150# before we ever introduce water into the system.The pressure regulators on my Overlanders were thrown away as soon as I went to pex.I really don`t think I will find a water service exceeding that pressure.Dave

We ripped out all the copper and replaced it with color-coded PEX. Hard part was planning the installation so that there was room for the PEX tool to operate where the last connector had to be. Most of it was laid out and assembled elsewhere, then put in place and the last connections made. We used the swaged copper ring fittings, because we feared that vibration on the road would loosen shark-bite or the other compression-type fittings.

So far, we're happy with the system. When restoration is complete and we're on the road, we'll have the final answer.

Europe has be using stuff like pex for years. Sometimes the US is so far behind. Take cell phones for instance.. ATT&T is the only company using simcards and that is limited.

I replumbed my new water heater manifold tree with PEX (my first experience with it) and I think it's the way to go. It's freeze tolerant to a greater degree than copper.

I used the crimp rings with the fittings and it was cheap and very easy. I was able to rent a crimper at Home Depot for $8/day. The only place I had a leak is in a location that I had a difficult time getting the crimpers into the proper position to crimp - and I redid it by cutting off the copper crimp ring with some end cutter pliers and recrimped a new one paying more attention to proper position before I crimped. A cheap plastic tubing slicer is also a good tool to have so that you don't mess up the PEX tubing sawing on it.

I've learned to sweat copper from YouTube and am under the mid-twin on the curbside this weekend to repair some questionable (and leaking) splices that were done at some point in Ohana's history. About $75 worth of gear and you're good to go on copper. I did treat myself to a MAP torch, but otherwise, the most expensive item is any copper pipe you buy. 3/8" IPS x 24" set me back $12. Oy!

I like to work with copper and love soldering the joints. I would not and will not use copper in a Airstream trailer though. Pex is also a great product. $40 bucks for a crimper and you are all set to go. Spend another $12 up front and get the little cutter that makes nice, clean cuts.
