Is putting a thermostatic valve on a new water heater the preferred method now?
Is this part of the 2009 Uniform code?
Are these valves adjustable if you feel the water is too cold?
What about if you want hotter water for your washing machine?
(I saw one diagram where they split the washing machine/dish washer water off from the water delivered to the outlets)
I have also seen mention that is wise to keep the hot water at 140 degrees and use the thermostatic valve to lower the temperature for deliver to prevent buildup of legionaires bateria.
