I wonder if it's from water expanding in the hot water heater. That might be pressurizing your system after you send a volume of cold water into the heater after use. Your pressure reducer valve might be acting like a check valve preventing expansion relief into the municipal supply.
- bbarnett 5y agoAn interesting premise, but I am on a well, have a pressure tank, and the well hose/pump has a check valve. (Otherwise, water could slowly drain back into the well) So think of it as a closed system, and it is a common setup, yet I have not seen this behaviour.
