Piping

Looks like I will be re-plumbing the 78.

Everywhere there is a tee there is a stain.

I wonder what you experienced rv folk would recommend?

PEX pipe and Sharkbite fittings.

A pvc/pex cutting tool, and if it a push together connection, that is about it. There is a special wrench for the push on, clamp down fittings, which you should be able to get at the same place you get the fittings.

You can find the pipe and Sharkbite fittings at any home improvement store. I was able to use ordinary tools to install my Sharkbite fittings.
Thanks, Derek

Personal preference here - I use pex and clamp-on fittings. I just feel more confident in them and their longevity. You do need a crimp tool for installation though, and they also sell a tool to cut the rings off if you need to make a repair or fix a leak. Tools, clamp rings, and fittings are available where pex and sharkbite fittings are sold too. Take a look at both options and see which you like the best.

I used PEX and Flair It fittings. No special tools required to assemble or take apart. You will need a PVC/PEX cutting tool.

PEX is really the way to go for replumbing. A bit of care in determining piping runs will save money on fittings; brass/bronze fittings are expensive these days, but the PEX is cheap. PEX is reasonably flexible, so installing in existing areas is much easier than w/ copper. Avoid significant torque at end joints. So far I've used the SharkBite push-on fittings; since we're remodeling section by section the kitchen area is still copper.

I like Pex as well. Sharkbite fittings depend on an o-ring seal. While o-rings provide reliable seals, they sometimes shrink or crack and i've seen heavily chlorinated water fatigue or deteriorate the rubber. You may also consider a manifold system where you have a centrally located block with shutoff valves and run individual lines to each fixture. No joints and you can use 3/8" line. All of these systems are much more forgiving in freezing situations than copper
as the plastic will expand without splitting (for the most part). The tubing may impart a plastic taste to the water when new but will not last long.

Charles, the thread seems to be about water plumbing, but your thread is in the LP gas piping forum. Are you wanting to redo the water system or the gas system?

So 3/8 is the standard for the system?

I saw the word piping and posted. My bad

I will be reusing the gas lines that are copper and will replace the rest.
