why do u need a hot water temp regulator coming off the water heater? why not just turn down the thermostat on the water heater itself?
Many local plumbing codes call for the heater to be kept above 140F to kill off any nasties that might be in the water. Since 140+ is unsafe at the tap, the code also requires a mixing valve to reduce the output to 120F or lower.
I installed my own water heater so I never bothered with the mixing valve.
ahh the joys of living in california...good luck getting a water heater to go over 140..LOL so many failsafes its stupid...never knew of a code like that...knowledge is power...
anywho i was doing some googling and found this http://www.plumbersurplus.com/pdf/01741.pdf
down on the second page has this
Valve is noisy • Water velocity is too high• Reduce water velocity with pressure regulating valves
so i'd assume ur running 3/4" to it, you could try http://www.homedepot.com/webapp/wcs/sto ... CvBUJZFk6I
it outputs at 50psi, so that should help you.
