Shower cartridge in upstairs hallway bathroom has failed, cartridge needs to be replaced asap. All other fixtures in the home had 120 degree water temps with no issues. Existing 6 year old direct vent water heater seems to be working as it should with no issues. Outer coating does have some rust spots, but the pan is not holding water at this time. The rust spots look they may have came from ANOTHER condensation drain failure because the previous installer installed a tee right at the condensate drain. Installed new Moen 1222 shower cartridge in upstairs hallway bathroom, shower is now operating as it should with no issues. Emailed a separate estimate for us to replace the existing mixing valve because it’s starting to seize up at the adjustment knob. Emailed copy of invoice to Kim’s email.
