Hi,
Can someone explain to me how the thermal expansion bypass on a water pressure regulator works? Like, after the water heater shuts off, is the regulator supposed to readjust the pressure back down or what? I can't tell if we need to get an expansion tank.
The pressure went up to 95 after the WH shut off. The regulator is set to 45-50 static pressure. The pressure is now 55 after 20 minutes (someone may have used water during this time). I know the bypass only works if the pressure is higher than the mainline -- the mainline is supposed to be around 80 -- I'm confused. Help?
