Title: Fails after 2 years
Review: I installed the first Watts 70A in 2007 behind my tankless water heater (steam boiler with integral domestic hot water heater). Well it failed after 2 years of use. The spring inside corroded and broke. I bought a repair kit, which didn't fix it. So I un-soldered it, soldered in a new one, and alas it failed after two years of use. Anyway, I pulled the guts out and turned off the cold supply to it, effectively bypassing it. I'm going to try a Honeywell mixing valve.
