Shower Valve

[MikeInCali]

Hey guys.

I'm looking to buy a 3 way valve for my new shower so I can have a rain head and a hand sprayer. Looking at faucet depot the rough-in valves recommended comes in 2 types 1/2 inch IPS and 1/2 inch CxC. Which do I need? They don't give a clue.

Here's the page. The rough-in valves are at the bottom: http://www.faucetdepot.com/faucetdepot/productdetail.asp?link={5BC6C86E-2C6D-4D73-A6DF-4DADB1B84581}&Product=9962

Also I'm wondering when I have the plumbers come in and install my new valves how will they know how deep in relation to the wall to install them? I'm getting it hotmopped and using 1/2 cementboard on the walls. Should I have it hotmopped and the floor mudded before the plumbers come in so they will know where to place the valve?

thanks, Mike

Mike, with that valve they are giving you a choice between threaded connections (IPS - iron pipe size) or copper sweated connections (Cxc). Choose whatever you'd rather work with. If in doubt, I'd recommend going with IPS. It's easy to convert that to Cxc if necessary.

Mike,

When working with plumbers, leave nothing to chance. You indicate where you want the valve to be located rather than letting them decide where to put it. Also, you should tell them the thickness of your wall + tile so they will know where to set the plaster guard.

I would get the hot mop in and all the related work, then cover it with cardboard or something similar, and let the plumber do his work.
