Kohler Rite-Temp Rough In Valve with Diverter (Replaces K-305-K) This Rite-Temp pressure-balancing valve works behind the scenes to prevent scalding and freezing for a safe, comfortable water supply. The valve features a high-temperature limit stop and an optimal comfort zone, so you can set a maximum high and then find and maintain your desired water temperature. The diaphragm design virtually eliminates freeze-ups from contamination and water debris. This valve integrates a diverter mechanism for seamless actuation of a handshower/showerhead application OR a showerhead/tub spout application. Finally, universal NPT and direct sweat connections need no additional parts for installation.
