    Answer

    Hi, this is Laura with Kohler Co. I am happy to assist you with your question. The transfer valve is also called a diverter valve; they are one and the same. You will need a single control valve to bring the water to the diverter. The most commonly used valve is K-8304. Trim kits for the single control valve and transfer valve are also needed. Thank you for choosing Kohler.

    Can I run this to a tub spout, a rain shower head, and a hand shower?

    Answer

    Hi Megan, my name is Sarah with Kohler Co. I'm glad to answer your question! The easiest way to accomplish this would be by using the Refinia shower faucet trim, K-11748 valve and the Awaken handshower. You would want to plumb the showerhead to the bottom port of the shower valve and the handshower to the top port. This will allow you to turn the water on to your showerhead and let you "divert" the water to the handheld with the push button diverter. If you have any questions or would like more information, please call our Customer Service team at 1-800-456-4537 M-F; 8am-5pm CST. Thank you for choosing KOHLER!

    Hi, this is Laura with Kohler Co. I am happy to assist you with your question. No; this is a transfer valve; this valve will direct the water between various applications, for example: a showerhead, handshower and body sprays, etc. Thank you for choosing KOHLER.

    Worked exactly as I had hoped, though not clearly captured in description. As others have noted, handle turns 360 degrees and has 6 stops, allowing individual use of each of 3 fixtures and shared use of 2 of each of the 3 fixtures at once (covering each combination of 2 because of 360 rotation).

    High quality
    Valve installation is straight-forward. Instructions are adequate. Cartridge is easy to remove to avoid overheating and to make sure pipes are flushed out after connecting pipes. Ports are large and water flow is better than the diverter valve it replaced. Using all 3 ports allows the valve to rotate either direction with no stops. In any position, either 1 or 2 of the outlets function without any dribbling from unselected heads (or spout). Note, the 6 detents make it easy to select any one or any 2 outlets.
