Cpvc.

Definitely cpvc

Cpvc for sure. Haven't run into a wood pipe issue every day.

Cpvc and galvanized for water lines. Touch either when they are existing and you pretty much have just made a problem.

Saw a large bore wooden pipe still in use in Jamaica bring water down out of the mountains to the towns. Wood is better than CPVC.

I work with them all and if I had to pick just one galvanized got to go.

Galvanized. Worst pipe for water ever just rusts & clogs fixtures with the debree. Cpvc my only issue is that it gets really brittle with age but you can still work with it, galvanized possible but wouldn’t recommend.

CPVC and galvanize

I’m not even a plumber and I know the answer is cpvc. lol

Galvanized and cpvc

Whoever doesn’t say Cpvc doesn’t even know how brittle those fuckers get after a couple years

This is a bad question. Most of these materials are no longer considered good.

Cpvc has got to go. Rumor has it the "C" in Cpvc stands for crap

lead water pipe I know it's not on the list but it has to be the worst one for you

Galvanized… definitely the worst, then copper right behind it

Cpvc is the worst

Cpvc or steel one sucks and ones a pain In the ass to install

Cpvc I’ll keep that wood pipe any day

Galvanized can kick rocks

Cpvc all day

Galvanized by far!

Galvanized by far

I wood honestly let the cpvc go

Galvanized replacing some this weekend rust running out of the hot side and cold side is plugged with rust

My whole house is cpvc so for that reason I have to say wood
