Function
The Caleffi PivotMixer ™ combines the AngleMix ™ three-way point-
of-distribution thermostatic mixing valve with a cold water cross and
pivoting brass connectors for easy installation directly on typical
electric water heaters and heat pump water heaters. It has unique
¾" pivot connectors that adapt to heater nipples spaced from
3" to 8" on-center. The cross for the cold water supply contains
an integral check valve for the flow to the mixing valve and ½"
NPT female threaded recirculation tap. The PivotMixer maintains
the desired output temperature of the mixed water supplied at a
constant set value compensating for both temperature and pressure
fluctuations of the incoming hot and cold water. The mixing valve
also features a thermal shut-off function that operates in the event of
a cold water supply failure at the inlet. The angle style body design
offers improved fluid dynamics for better performance and reduces
installation labor and materials. The mixing valve has been certified
to ASSE 1017 and Low
with codes IPC, IRC, NPC and UPC for use in accordance with US
and Canadian plumbing codes, and standard NSF/ANSI/CAN 372,
governing low lead material content.
