Thread: "rough in" questions

  1. #1

    Default "rough in" questions

    Hello all, I was refered to this forum by my good friends at the John Bridge site. I am in the process of a shower remodel. here is my plan: Install a new 3/4" thermo valve on the incoming 3/4 hot and cold lines. Stub out of the thermo valve with 3/4" and then "T" into 1/2". 1 line going into a 1/2" contol valve to feed shower head on one wall and the other 1/2 line to another control valve on the opposite wall for a hand held shower head. Any issues so far??
    Now to some finer points. What are some thoughts on the Kholer Mastershower products, valves ect. I am looking for something that wont break the bank, but don't want to tear into my tile wall in a year later to repair the themo valve or control valves. Is there a better way to run 2 shower heads without using a therostatic valve and control valves or is this pretty much standard. Is there a concern with thermo valves that hot water may "syphon" off into adjoining cold water sources such as faucets, toilets ect. Well, enough for now!!! Thanks in advance, Pete

    Default valve

    My opinion of most Kohler valves is that they are overpriced and not necessarily better operating or a better value. There is no reason to tear out the wall to repair any make or model of valve unless it is damaged by the repair person, in which case it has to be replaced.
