New bath/shower valve

I am re-doing a bath.... tore the walls down to the studs.

I will have to post a picture shortly....

Right now I have 1/2 inch copper h/c into the existing valve... it's all soldered in.

I will cut that out. The new valve is part of an American Standard Standard collection tub/shower system. It has threaded valves. Can I transition to CPVC...Pex, or sweat new copper? I have mixed success with sweating, but am getting better at it.

Those DIY books show CPVC everywhere.... I have done some PEX with sharkbites..

Take a piece of 1/2" pipe and see if it will fit inside of the new valve...many allow either a threaded connection, or to sweat in a pipe directly. You're better off with copper in this instance since it is easier to anchor things and sweating is likely to work better than a threaded connection where you can't get to it easily. Take the cartridge out clean and flux everything at the joint, and go for it.

i am not opposed to doing the sweating... i think i would have to sweat to a threaded fitting.

also please notice the existing galvanized tied to the copper...this galvanized pipe has a larger outside diameter than the copper... i get great pressure out of this head..and am wondering if it has anything to do with the galvanized. Conventional wisdom says no..but just asking.
