    Hi all,
    Wondering if anyone has ever used the tub filler oulet on a tub/shower valve (has the diverter built into it right above the handle) for a second shower head?
    I have a valve with a tub filler but since it's going into a shower, I was planning to use the tub filler outler for the main shower head, and the shower outlet for a second handheld shower. I don't need to use them both at the same time so I'm hoping this will work. The only problem i could see is if the tub filler has too much backpressure when hooked to a shower head, and causes some water to bypass back to the handheld shower. Thanks in advance for any info if anyone has tried this. :)

    Tub filler outlet --> to shower head
    Shower outlet --> to handheld shower
    Diverter built in to the valve, allowing selection of either regular shower head, or the handheld shower.

    Like this picture? Found this in Elgin in a house that was only 2 years old.

    Good one ;)
    Not exactly the "application" I had in mind. haha
    I wanted the second shower head to be mounted at about 4' - 5' so my younger kids can use it. Also handy to have the handheld for rinsing the shower out when you clean it (it will be tiled).

    I couldnt get the other shower head in the picture. Both are there. And yes you can do it. Any plumber can set you up the way you want it.

    shower

    There is absolutely no doubt that the shower head connected to the spout opening will cause the upper one to ALWAYS operate except when the diverter is activated to send all the water to the upper one.

    I would use a handheld on a bar so it could be moved to where you want it. You will need a different divertor valve to select between multiple shower heads...the tub spout won't cut it as noted. The path to the showerhead is always open in that design, and by making any restriction to the flow out the tub spout, water will back up and start to dribble out the top. You need a valve that will physically shut off one path or the other.

    OK I hear what you're saying. So it would probably work to just put a valve right on the handheld then, correct? Thanks for all your input. Better to know now than after the walls are closed up!

    No, you need a real divertor valve that will (normally) give you water flow to only one, the other, or both. It effectively gives you a shutoff for each showerhead, with a third position that supplies water to both. Exactly how a particular one works will be different...if you only want to do one or the other but not both, it gets simpler and less expensive. It's all in one valve. Something like this would work http://www.groheamerica.com/lib/8/catalogue_p1/gw/lc25/29714000_GW.pdf

    Pick one from your manufacturer of choice so you can get trim to match. While the functionality is common, trim is not between manufacturers and even within the different choices of rough-in valves from the same manufacturer.
