    Cold/Hot Water "Shock"
    My house is approx. 20 yrs old. Is there a regulator I can put on my plumbing to stop cold/hot water "shocks" while showering when someone else flushes a toilet or turns on water elsewhere in the house?

    Hey Tami..

    Tell me... you have a two or three handle tub/shower... yes?

    The only real solution to this is to install a single handle, pressure-balancing valve... such as the symmons valve (click on link.). Here, when another fixture uses hot or cold water (or both) there is a corresponding drop in the opposite water being used and you notice a drop in pressure/volume... but you do not notice a drop in temperature... that make sense?


    Site Search Results...

    There are many different pressure-balancing valve choices (see google.com).

    If two or three handle, you will need a transition plate to convert from two/three handle tub/shower valve over to a single handle, pressure-balanced valve (see pic.).

    Answer questions.. let me know what you can... Mark
