Off the wall question

I have a copper supply line that runs the length of a crawlspace to an outside faucet at the front of the house - Living in upstate NY about every five years or so I don't get the water shut off on the first or perhaps second below freezing night......anyway the pipe has burst again and in the past I crawl in and I solder in a new piece.....do PVC supply lines also burst or are they more forgiving.....? Thinking that I could replace the copper run...?

A. I'm not a pro plumber...just a 50-year+ DIYer.
B. Copper will freeze and burst. PVC will freeze and burst. CPVC will freeze and burst.
C. PEX, which is what most pro plumbers are installing here now, will freeze and expand but rarely burst and will return to its original shape. You will have to have transition fittings from copper to PEX and a PEX connection crimping tool (1/2" if that's what the water line is). It comes in flex line rolls and you can probably rent the crimping tool.
Good Luck!
