Customer stated there was a leak coming from the water heater. Further inspection showed that leak was actually coming from expansion tank. Water pressure was also checked and registered at 85 psi. Customer was informed of the issues and elected to change the PRV as well as expansion tank. We also informed the customer of the of the water heater and recommend replacement. Work was thoroughly tested for leaks and pressure was set to 65 and expansion tank was set to 75. Thank you for choosing TE.
