Repair or replacement of commercial shower components, rather than replacement of the entire unit, saves money and resources. Zurn’s diverter stem repair kit (Part no. RK7000-50BN) is made for use with Temp-Gard® I Series Z7220 shower valves manufactured in the year 2000 or after (with a white stem). Temp-Gard® pressure-balancing valves maintain a consistent water temperature. Zurn replacement parts are manufactured to provide long-term durability for commercial showering applications.
