    Default Water temperature fluctuation

    Hello gentlemen, Just in a condo building that has a central water heater. The condo unit has 2 showers. The hall shower operates properly. The master shower starts out with a normal (warm) temperature than it starts to fluctuate between scolding hot & ice cold. Any ideas to the cause.
    Thanks in advance.

    Jerry, you forgot to post code text.

    Individual shower valves. Individual shower and
    tub-shower combination valves shall be balanced-pressure,
    thermostatic or combination balanced-pressure/thermostatic
    valves that conform to the requirements of ASSE 1016 or CSA
    B125 and shall be installed at the point of use. Shower and
    tub-shower combination valves required by this section shall
    be equipped with a means to limit the maximum setting of the
    valve to 120°F (49°C), which shall be field adjusted in accordance
    with the manufacturer’s instructions. In-line thermostatic
    valves shall not be utilized for compliance with this
    section.

    Huh???

    There is code text about mixing valves which may be bad? Where?

    By the way, when posting code text, which is what it looks like you did, you should first state what code and edition it is from.
