    I am installing plumbing in my bath to include two showerheads instead of 1. I have attached 2 diagrams of how the lines will be setup. Does this look ok to you guys? Will there be any problems I should consider with this setup? The dotted line represents copper line I am running above the drywall ceiling of the shower.

    I have looked into the jetted diverter that has an additional outlet on it, but I believe that is for shower only setups.

    I will be using the Addison Tempassure 17T Tub/Shower Trim (T17T492-RB), the Addison 3-setting diverter (T11992-RB), and the slidebar Handheld as the secondary showerhead (54713-RB).

    Thanks in advance for the advice...this forum has helped so much in my renovations!!

    If the diverter has an opening on the right side, which we cannot see, it CANNOT be capped, but must be teed into one of the other outlet pipes, probably the primary shower riser in your case.

    Hj...

    Which of the following will work?

    A) untitledA.JPG

    or

    B) untitledB.JPG

    Sorry I wasn't clear on your suggestion...
    I was thinking to add a Female 1/2" Adapter to that open end and just cap it. Thanks for the heads up...

    Thanks again!

    On your first diagram, the primary showerhead would always have water when any shower is activated. Are you using a diverter tub spout? If not, then I think you'd want to run each of the outputs to one of the diverter ports: tub, primary, secondary. The order you attach them would determine which one came on when. Note that with a diverter valve, you can end up with a slug of cold water in the line, since it can't drain back to the tub spout and out. This can be quite disconcerting after you get the tub spout temp just right, then switch to the shower!

    I will be using a diverter tub spout...in that case, can you clarify if I should be making any changes to the routing of my lines?

    Also, HJ if you can comment, which of the two diagrams looks ok for teeing the open end of the diverter valve?

    If I was using a 3-port diverter, I think I'd use a straight tub spout...one less thing to go wrong. If you are keeping the tub spout, then the second drawing should work.

    The bottom one is the only one which would work. The top one connects the shower directly to the valve, bypassing the diverter valve.
