Customer called about a leaking shower handle. Upon arrival, also found that the tub spout was always dripping. Provided pricing to replace the Rite Temp cartridge within the valve and also to replace the valve. Explained we would have to order a gold trimmed trim kit. Customer agreed to the cartridge replacement. Isolated water at the isolation valves on the valve. Removed previous cartridge. Inspected valve, no signs of damage. Installed the new cartridge. Tested, water lines coming in are backwards. Removed and reinstalled the new cartridge upside down, tested. No leaks detected, working as intended. Adjusted maximum temperature to 120 degrees Fahrenheit. Caulked trim with clear silicone. Cleaned work area. Thank you for choosing CPI!
