Mr Swirl The Friendly Plumber

This is my second time using Mr. Swirl . Christopher showed up on time, diagnosed problem quickly and he set out to obtain the gauge I requested to be installed. Gauge Installation and repair were done quickly and clean up was adequate. UPDATE** to this repair.. Pressure builds up in House water lines higher than 140 psi!! ( Dangerous levels) Have to turn off water heater when not home to prevent pressure build up. Called Mr. Swirl and informed them... still waiting on their response and solution to what appears to be a misdiagnosed repair.Update..Mr. Swirl wanted to perform a solution to my problem that would have meant hot water wasted. Unsatisfactory resolution to me. I insisted on the installation of a Thermal Expansion Tank and an anti back-flow valve to solve the problem. This was installed and appears to have remedied the pressure build up problem. However.. A non-potable water Thermal Expansion Tank was installed instead of a potable water Thermal Expansion tank. Have been in contact with the tank manufacturer, (Watts) to see if what was installed is appropriate to use for this application. Waiting on their response. UPDATE... Watts representative stated that the Thermal Expansion Tank installed is not correct for my application. Mr. Swirl acknowledged the error and installed the correct one. All seems to be functioning as required and the excessive pressure build up problem appears to be rectified.
