Homeowner has a toilet that is constantly running. The fill valve on the toilet has failed. Discovered that the stop valve for the toilet has also failed, and does not fully close. Upon further investigation, I found that the thermal expansion tank has also failed, and the water pressure upon arrival was 80 PSI. Cut and removed old pressure regulator valve and shutoff valve. Installed new quarter turn ball valve and a new Watts 25AUB pressure regulator. Installed approximately 2’ of copper. Installed a new bonding clamp as there was not one present upon arrival. Pressure regulator is set to 60 PSI. Removed failed thermal expansion tank. Cut and removed 90 and copper female. Installed expansion tank bracket on joist above water heater. Mounted new expansion tank to bracket. Installed approximately 4 feet of copper from cold water pipe to new expansion tank. Attached onto existing copper. Expansion tank is charged to 65 PSI. Removed failed fill valve, flapper, and failed stop valve fo
