Copper to PEX adapter question

[MTLMIKEscott]

I have copper but I plan on renovating my bathrooms and making the switch to PEX. When installing the adapter, should I be using a simple sweat to PEX adapter? Is installing a sweat to PEX shutoff valve common practice or would that be unnecessary and possibly even give be negative in that it would be restricting water flow for no reason.

I prefer a copper to PEX adapter that is sweated. You can also Sharkbite it, but most plumbers prefer not to. I still lean to copper stub outs for my compression stops. Some plumbers are Sharkbiting those on PEX or using expansion stops with PEX. So many choices.

Thanks Terry! Interesting you mention copper stub outs. In my area (Montreal) I notice most houses with PEX do not use copper stub outs for toilets, they bring the PEX out as a stub out with a visible crimp ring. A positive being one less connection behind a wall but for this method, is the only drawback cosmetic? (ugly compares to copper stub out) Thanks
