Default Running new plumbing lines: is everyone in agreement that pex is the way to go?

Finally getting to a remodeling project. Have to replace copper through concrete where a hallway will go. Have to run it overhead to replace.

Buy a good tool for the crimps and figure out what is available locally. There are a few different systems. Mine are all the stainless collar crimps. Can get the stuff an Home Depot but I usually swing buy the local plumbing supply house.

my brothers house was built with expensive unions and take a special dedicated tool. Then there are the expansion collar types that require a very expensive tool which expands the collar and pipe which then slowly shrinks. This was used for my heating system. Not sure if it is used for standard plumbing.

once you assemble sections don’t forget to crimp ALL the crimps. Males a mess when you turn the water back on.

the only negative I have heard is if you have a mouse problem they can potentially chew through but not very common.

Do you have permits for all this work?

It's called Uponor and yes, it's used throughout the structure.

What? Are you the building inspector? Answer the question if you can. Otherwise mind your own business.

I would take that to mean “ No Permits “

Last fall I sold a house in Maryland that had polybutylene pipe. The buyer wanted it replaced. His offer was good enough that I hired a plumbing contractor that specialized in repiping. I had a choice of copper or PEX. PEX was cheaper and had a better warranty.

You do realize there are places in the U.S. where there are no permits required to build, much less remodel.

I like pex but after having an issue with a rat chewing dishwasher lines several years ago, I've been wondering if they would go after pex?

Exactly. The attitudes around here are a pain in the ass sometimes.

My county doesn't require permits for anything smaller than a 3 family dwelling.

Could go CPVC, but thought less joints would be better, plus since it has some flex to it I can make wide 90 degree angles. Now I am wondering about the fittings. My camper uses the crimp style, so figured it might be handy to have for future work there too! Does anyone know if most plumbers are using the crimps on new construction mostly? Or are the flare spreading tools that much better?

I use Pex and brass pex fittings . The crimp tool is available at Home Depot. A local plumber said that if the house is on well water, he uses plastic fittings.

Look for a crimper that the head turns on a 90* angle, easier to reach in for the tight places.

I’ll take PEX over copper or cpvc any day. Having installed miles of poly-butylene I still have no faith in plastic fittings. As for the rodent issue, they like wires too. Keep your house critter free and enjoy
