With the 40 gallon Water Heater set to 120 dF I would run out of hot water before I was able to fill the roman tub.
I set the WH thermostat up to 140 dF and was able to fill the tub without running out of hot water. (South Florida, cold water temp was 76 dF last night) Final temp in tub was a very warm 106 dF. I don’t want to leave the WH set that high as I have a 7 year old grandson who spends several nights at our house.
Base on this I plan on installing a 50 gallon standard GE WH set to 140 dF and Watts L70A Tempering valve set to 120 dF.
The Watts installation instructions state “install valve body as illustrated in diagram. Valve must be trapped 8" to 12" as shown.” What i is shown is to install a 8”-10” trap and mount the valve in an awkward position below the water level of the tank. Pictures of real life installations I’ve seen just shot the valve mounted above the tank without any trapping.
What is the purpose of the trapping and is it critical? Will it work reliably without being trapped?
