I have a buried water line with is 3/4 blue pipe, probably
polybutylene, that was put in 30 years ago that I need
to connect to 3/4 CPVC line.

I’ve heard that regular CPVC couplings and cement are
not a good way to do it.

Does anyone have any suggestions on how to make
the connection properly ?



Just sweat them together. Don't forget to use flux.
