I glad to see this thread generated some interest.

To be honest I'm still a little confused.

I think Wirsbo AquaPex was the fresh water stuff.

Re-checking http://www.pexsupply.com

I cannot tell which fitings get used with the crimp system & which get
used w/ the expander system.

I've only seen the stuff on the web never in person.


I looked at the air & the battery powered expander; a little pricey.

I too was concerned about my arms getting tired but I only have about
25 expansions per house. What really sucks it that the expander heads
for the air, battery & hand expander are all DIFFERENT!

I have a contractor friend who moved from CA to TX a few years ago & he
was just switching to PEX. He loved it.

I'm pretty old school been using copper all my life for new work &
have done a fair amount of galv steel repair. A year ago I replaced
the street to house galv line with 1" CTS type K just because. that's
what I use. If I thought about PEX, had the tools & experience I might
have used it but old methods die hard.

I think PEX IS the next copper; anyone with bad PEX experience?

I know the stuff is very sunlight sensitive.
