Pex shower rough in valve, what goes to the shower section?


Doing pex I always rough the entire shower body in copper and transition a couple feet away from the shower body. 10ft of half inch copper and a few fittings really isn't that expensive.

Have you guys ever used a 1/2'' male to 1/2'' compression fitting . The 1/2'' male pipe fitting would screw into the valve body and a 1/2 copper pipe would slide into the other end and tightened in place. If the tear drop fitting on the shower end or spout end is off a bit you could loosen the nut on the compression side, turn the copper pipe then snug it up again. Saves soldering once everything is in place. What do you think. Doug

Depending on the shower valve you can use a female or male pex adapter off the valve into copper then to a shower ear pex and secure it to a 2x4 then the spout. Just use copper everyone is right the difference in ID between the pex and copper will make the shower head drip.

Adapters



Drop ear

Say plumber 101 have you used the brass compression fittings much for bathroom work or for joining two pipes together or quick repair. If so how tight do you tighten the nut to the sleeve so as not to overdue it yet not have it leak.I was told to snug it up hand tight and then half a turn with a wrench. Thanks.Drumstick

Since shark bites I havn't used compression but you are on the money snug and about 1/4 to 1/2 more then check for leaks.

If I can't us a SB I'll sweat a fitting in

Hey Drumstick,

I absolutely agree that you should use copper for the spout, but if you are going to use Sharkbites for the shower riser why not just use PEX? It will be lots easier and as long as you secure the Drop Eared Ell at the top it will be fine.

Thanks for the help guys. I think I'II use pex on the hot and cold risers with 90 degree pex fitting, but stick with copper for spout and shower head.

This is too late for the original poster, of course, but for future researchers--I'm plumbing showers in my house right now, using pex. I went to a local plumbing supply house to get some shower valves and found that Delta makes valves with pex fittings on the hot and cold inputs. As far as the to showerhead and bath connections, you still have to get female to pex screw on adapters. Use four wraps of teflon and crank them down good. I think Zurn also makes some basic shower valves with pex fittings.
