Installed a gas hot water tank two weeks ago and worked great. Today it started leaking out of the pressure relief valve. Called the company and told me to install a thermal expansion tank.Bought the thermal expansion tank and don’t know what to set the pressure at. My static water pressure (at rest if I don’t use the water for a minute) is 100psi, when I run the water it drops down to 50 psi. Do I set the pressure of the tank to 100 or 50?Thank you for any help you can provide me. via /r/DIY https://ift.tt/2ITkiYb
