Series 105 and 115 TempTAP™ thermostatic faucets feature an advanced thermal actuator to provide the latest in thermal protection. The single-lever cartridge, with integral ceramic discs, provides both temperature and volume control. TempTAP™ automatically mixes hot and cold water to deliver pre-set water within a specific range. In the event of cold water failure, the thermal actuator virtually shuts off the flow of hot water. TempTAP™ is listed to ASSE 1070, IAPMO cUPC, and NSF 61 Section 9 Annex G.
