Question about Watts Premier Watts LF7 U2-2 3/4 3/4-Inch lead free Dual Check Valve
I have installed a back flow preventer at the water inlet to my house, per my town's requirement. This went in during the summer and I've had no real issues other than the annoying sound it makes when water is flowing. Now that it is winter, I am having issues with the water heater generating very high pressure (>150 psi) in the system as it heats up the water after everyone showers. The water heater has a pressure relief valve which now releases water regularly, and the plumber installed a pressure meter to see how high we're going (this is how I know we're getting above 150 psi and that the relief valve isn't broken). Is there a way to make this all work without having such high pressure cycles in my system? We've already had one pipe leak due to the high pressure (ironically, on the water heater, but it could happen anywhere in my house with all the pressure cycling going on). Help!
Add a variable regulator to the house side of the check valve. Also add a pressure tank between the regulator and the hot water heater.
