TEMLOCK Thermostatic Mixing Valve adjusts, maintains, and limits the hot water temperature settings to provide comfort and protection at home. This valve efficiently offers anti-scald, anti-chill protection while increasing the amount of safe, usable hot water, and compensating for both temperature and pressure fluctuations.
TEMLOCK Thermostatic Mixing Valve has an adjustable temperature control cartridge and an all lead-free brass construction. It uses a German-made wax-based thermostatic engine and features rough-in 3/4-inch union sweat fittings, and hot and cold check valves that prevent possible back flow on water supply inlets.
TEMLOCK Thermostatic Mixing Valve is factory preset at 130 Degree Fahrenheit, and is adjustable from 100 Degree to 140 Degree. The operating water pressure range is 30-145 psi. Hot and cold water pressure should not differ by more than 20%. TEMLOCK Thermostatic Mixing Valve is rated for 200 degree Fahrenheit as its maximum incoming hot water temperature.
INSIDE THE PACKAGE:
One (1) Thermostatic Mixing Valve, with integral check valves
3/4 inch union sweat fittings

I did not know if it would work, But realized by hooking the supply to the inlet of the exchanger and the cold of valve I did not have a pressure drop so the valve can work. It seams to have enough flow. Hope this is helpful.

The sweat joints are way too small for my standard 3/4" copper pipe. I tried the copper pipe with other fittings and they fit. I measured 1/32" difference between the Temlock ID and the pipe OD. Way too much to sand off. Useless.

I had tried to purchase Honeywell thermostatic mixing valve. I believe I ordered two different styles from Amazon. None were as listed. None. I finally ordered this valve. Since we were using PEX, had to sweat PEX fittings on which made for a much longer valve assembly. Water heater is set for 140 degrees Fahrenheit. Mixing valve arrived preset to 120 degrees. By the time water reached point of use it was not as hot as some users wanted. Just like opening a sink faucet, gentle turn of the valve alters the regulated temperature.Note: If this valve is user accessible it can be set to dangerously hot temperature very easily.

The existing mixing valve on my water heater failed, and no stores in the greater Seattle Area carried one (quick aside-- are you kidding me?). Ordered this on next-day delivery after worrying if it'd fit, but it was a 1:1 match. Slotted in perfectly. Pain to install, but the blame for that really falls on the plumber who set up my water heater, not on the manufacturer.
