Well I replaced a bunch of copper at my GFs nieces home, copper had frozen and burst.



Did you use PEX? That may help in the future.



yep PEX its cheap easy to install, freeze tolerant and sharkbites make it dead easy



While the PEX pipe itself is not supposed to burst when frozen, I

question what happens to the brass fittings, and particularly those

sharkbites????



I also wonder how CPVC pipe compares as far as staying intact when

freezing? CPVC is even easierr to install than PEX, and while the pice

prices are about the same, the fittings for the CPVC are much cheaper.



I do agree, copper pipe is probably the worst for durability when it

freezes. Even the old galvanized steel held up better.

CPVC is easily damaged by freezing.....

Sharkbites are heavy brass casting so they are likely pretty freeze tolerant.....
