Customer had a leaking Moen shower cartridge. Installed a new Moen Posi-temp shower cartridge and replaced the positemp adapter because it broke. Noted to customer that the shower arm comes out of the wall uphill and it will still take a lot of time for it to stop dripping. Removed shower head after cartridge install and ensured no water was coming through. Tested work to ensure proper function and no leaks, none were found.
