Question CPVC OK To Support New Tub Faucet Spout ?

All,

First time poster here. Ran a search on this issue but did not find the question answered, so I thought I would put a posting up.

I'm in the middle of a bathroom renovation and almost done with the plumbing. Based on the tight quarters and my lack of sweating skills, I have decided to go ahead and use CPVC pipe, and have already installed it on the supply lines and shower head line. My question is regarding the use of CPVC for the short run from the control valve to the bath faucet. The run is only about 10" down out of the valve to a 90 degree elbow, then out to the faucet. The faucet head itself has a threaded female connection.

Would it be feasible to use CPVC for all this as well ? My concern is that CPVC does not seem as solid as copper (obviously, being plastic), so I'm not sure if I'm taking a big risk that if the faucet gets hit hard, fallen on, etc, that I might have a greater risk of cracking CPVC connections behind the wall. Granted, the durock and tile (once fitted) will offer some protection against vertical stresses, and once the faucet is installed the only risk should be the connection getting pulled "out" of the wall somehow (as the faucet itself will prevent the CPVC from being stressed by being pushed in towards the wall). Additionally, the area where the connections are located are behind a removable panel, so I should have access if there is an issue (and know about it quickly, if water stops coming out of the shower).

I have considered making it copper, but my main concern is the threaded end inside the faucet. Once the wall and tile are in, I don't have much margin for error when sweating the 1/2" copper to threaded male copper adaptor on. Additionally, I think that if I don't get the orientation of the adaptor right, the faucet will not point down when fully tightened. This can be easily be resolved with CPVC by tightening the CPVC to female adaptor in the faucet first, dry fitting the pipe to the right length, then gluing it all together.

Any comments ?

Thanks in advance

Pete: Welcome to the forums! From the diverter, you may want to consider using 1/2" galvanized pipe, and elbow and nipple. It is alot sturdier, and can handle the occasional "oops" when someone grabs it for some reason. If you are handy at soldering (and it ain't rocket science), you could use copper, but cpvc is a stretch.
