Water temp changing with pressure changes
As our shower is running and the water pressure goes from high cut out to low cut on the water temp changes. With the higher pressure the temp is hotter and gets cooler as the pressure drops. There seems to be about a 10-15 degree change from high to low pressures. My tank switch is set from 35-65 psi and is working correctly. Any idea where this change is coming from? My hot water heater is new and the bladder pressure in my tank is set about 5 psi below the start pressure on the switch. Thanks for any ideas.
