Our faucets and their parts are guaranteed for a lifetime, but just in case you'd like to make some repairs on your own we've made this MultiChoice Universal Thermostatic Tub and Shower Cartridge Assembly available for you to order. Delta's dual-function thermostatic valve cartridge keeps water temperature consistent (within 3.6°) by actually measuring and monitoring the temperature of the water and automatically adjusting the water mix to maintain a more precise water temperature. Temperature can be set in order to remain consistent shower after shower.
