Kohler shower heads just dribble.
Two bathrooms in this 11 year old house have some kind of high end shower heads in them. There are two big fat heads at about chest level and the regular overhead showerhead. There are three rotating adjustment faucets, one is for temperature and the other two adjust volume and which of the three faucets turns on. In addition, someone has added (?) a handheld shower in each shower enclosure. I cannot get any of the three Kohler fixtures to work right. Also, the temperature regulator does not adjust the temperature. It is either very hot, or not hot, and it does not seem to make much difference how I turn it. Hot water does adjust OK in the tub and sinks which have separate hot and cold faucets. I have resorted to just using the handhelds and praying I can get in and out without freezing or scalding myself. Where do I even begin??
