Thermostatic Mixing Valve, or a coupla' check valves and a ball valve?
In our area a thermostatic mixing valve is REQUIRED for nursing home
and child care facilities. Nothing else will do. Having installed and
serviced such valves for larger facilities, $100.00 does seem CHEAP.
You should see what a 2" valve costs! Thou$ands of dollars! And they
have to be tested regularly too!
