Copper to PVC

I have a length of cold water copper pipe running from the basement to the garage (about 20 ft or so) and ending up as a faucet for gardening on the outside of the garage. I forgot to shut the water off during the winter and the copper pipe, with all its joints, broke in several places. There are so many joints that I'd like to convert the whole length to PVC. If I can use one length of pipe without joints in the run that would be great. I just need to know what type of adapter and/or fittings I need to do this. I'm plumbing challenged!

You would need to use CPVC, assuming it is allowed in your community. there is a copper-cpvc union that provides a sweat joing for the copper, and threaded coupling.

It may be easier to use pex and sharkbite fittings available at the big box stores. the pex is easier to work with, assuming you don't need any 90degree turns in a small space.

If I might make a recommendation - I have an outside faucet with about a 12' run in the ground, about 6" down, with about a 30' riser to a hose bib. It has a shutoff and a "drain port" where it leaves the house. It was all Schedule 40 PVC. I'd forever forget to shut the thing off before a freeze. And every year, the thing would bust all to heck. For reference, we don't have basements and "dang it's really cold, turn up the heat" here is mid 20s and that's seldom more than a couple of days. I replaced that line with a chunk of 1/2" galvanized and - still forgetful - haven't had to replace any pipe in 3 years.
