What the best way to connect Cu plumbing to a PVC supply line.
Pipe is 3/4 inch.

Ive fixed this a couple of time and had it professionally done but the screw
together joint made of a threaded male PVC adapter and CU male threaded
adapter eventually leaks. I am thinking I have an expansion issue here and
I am going to try to make an expansion jiont using a loop of flexible copper
to connect the two.

Any other opinions are welcome and appreciated.

Thanx
Jimmie

A real plumbing store might have Fernco fittings that size.

If its CPVC, then these things are the nuts.

Some of the Borg stores carry them.
If it is PVC & I were in your shoes I'd be tempted to look for a PVC
to CPVC adapter- then use the CPVC fittings.

I've used "Male" PVC adapters threaded into "Female" metal adapters (brass,
copper, galv, etc.), with a little teflon tape, and they've always held up
well for me. Just don't use "Female" plastic adapters (PVC, CPVC, etc.).
They tend to crack open along the seam.

In any case, my preference is to use the adapters that have a rubber gasket
in the middle. Kind of like a union, with a brass piece on one side and a
CPVC piece on the other. I've seen these with threaded brass or sweated
copper fittings on the metal side, but don't know if I've seen a plain PVC
version or not.

A Sharkbite fitting.

PVC male adaptor > brass coupler > copper male adaptor. Or substitute a
union for the coupler.
