Shared use of a shower mixer?

Katydid · 07-10-2006, 06:11 PM

With the walls open to the studs, I can see the back side of the shower mixer. (Old and new bathrooms share this interior wall) It's a seldom used shower and not really needed. The valves are inside the new(under construction) shower stall where I really could use a (second) source of water for a hand-held fixture near the bench.

Is it possible to tap into the existing mixer/valve or copper H20 pipes
and use that source to install another fixture on the oppolsite side of the wall?

If your asking to install a new vavle on other wall, sure you can, as long as you tap into 3/4" cold an hot feed from somewhere, and run 1/2" lines to the valve from there.

Do I understand correctly?

Does that mean that is IS O.K. to tap into one set of water pipes to feed two different shower heads? (Only one would be in use at a time, of course.)

Thanks again Ron, for your help,

Katie

Will this be the hot and cold supply for the new shower stall?
Or will this be for another fixture? If so, what type of fixture?
Are these 1/2" copper pipe or larger?

You can use these for supply for a your new shower from the old shower if you connect before the old mixer and not after.

If both showers are used at the same time then you may see a reduction in pressure.

What redline said,

You must tie in before the existing valve, and not after it.

Yes, the pipes bringing the hot and cold water are 1/2". I haven't chosen the fixture yet, but I know a trustworthy plumbing supply retailer who will help me decide, now that I know what to aks for. Thanks so much, guys. -Katie
