How to Replace a Leaking Bathtub / Shower Valve - Copper to PEX

[@TyronC199]

how did you cut the holes on the backside wall ?

I first found the studs and cut between them where I thought the valve was. I used a drywall saw and my oscillating saw to cut through the wall.

Thanks for the video , just have question what’s the size of the pipe that connected to the cooper elbow?
The only size I can find even with link you provided the pex size is 3/8” .

All of the piping is 1/2"
