Nick called out spartan plumbing due to his shower valve in the master bathroom. Currently valve stem metal had snapped off with trying to replace the cartridge. Homeowner has the Moen cartridge himself. Toby the technician evaluated the issue. Toby provided multiple options for removal and replacement of valve cartridge and also replacement of the entire valve. If replacement of the cartridge does not work then replacement of entire valve will be necessary. Toby replaced shower cartridge and tested for leaks. No leaks found at this time. Also reinstalled previous faceplate and handle.
