All Delta tub and shower faucets are engineered to keep the water temperature within a safe ±3.6° F (±1.7° C)*. This technology makes sure your family doesn’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.
Delta thermostatic tub and shower faucets are built with TempAssure valves, while pressure balance tub and shower faucets are built with Delta Monitor valves. Both feature an adjustable handle limit stop that, when properly set, helps ensure the handle cannot be turned to a position that is too hot for comfort.
*Requires inlet water temperature be set correctly. May require seasonal adjustments.
