Delta showers with Monitor pressure-balance valves are engineered to make sure you don’t experience a sudden and possibly unsafe change in water temperature as a result of running water elsewhere, such as using a dishwasher, flushing a toilet or running a washing machine. By integrating separate controls on one trim with the MultiChoice Integrated Shower Diverter, we’ve streamlined installation and your shower style. You can install with confidence, knowing Delta products are backed by our Lifetime Limited Warranty.
