GP77759 Mixer Cap for Pressure Balance Valve

GP77759 Mixer Cap for Pressure Balance Valve

Q: I'm having trouble with the water temperature. After about five minutes, my shower goes cold even though there is still hot water at the sink.

I just spoke with Kohler Customer Service about a similar issue I'm having. They said issues related to temperature are caused by the PRESSURE BALANCING UNIT. If you had a leak or non-temperature issue, then you should replace the MIXER CAP.

Q: how to adjust the Kohler shower facet to get hotter water

There is a safety stop that is adjustable with an allen wrench. This is to prevent scalding. I just adjust my water heater to a safe temp and leave the the stop screw out all the way. The allen screw is just behind the O ring where the the knurled shaft is. I wish I can adjust it so it wouldn't drip when off, which is always worse in the winter. I always replace Kohler products when it"s practical, but in lieu of tearing out the shower I replace the mixer every couple of years.

Q: does it come with new o-rings?

Yes it does, everything needed for a complete swap-out is there.

Q: When i turn the water on . water comes out the shower head without even pulling up on the thing on top the spout. what part do i need? thanks

Assuming your handle rotates (turns, not push/pull), turn the water off with the handle then realign.
