How do you connect a PVC pipe to a copper pipe?

Answer 1

I WOULD NOT

I wouldn't I would use copper strictly

The above is clearly opinion and not very helpful if you have existing PVC pipe or have an application which requires it. Try searching on "PVC to copper adapter", you should find many to various adapters and should be able to find one to fit your application.

Answer 2

I've seen fittings for that situation in the Plumbing section at Home Depot. Most hardware stores should have those fittings. I would be careful not to heat up the PVC too much if you're soldering to the copper. You could use copperbond epoxy instead of soldering next to the PVC.

Answer 3

With a fitting called a hubless or no-hub fitting.
