Abstract: A system for removal of Moen cartridges or cores and sleeves from plumbing valve bodies is facilitated with a tool having concave, cylindrical billed jaws on a vise-grip pair of pliers and a specially built extraction tool on the screw end of the vise-grip. The outer shape of the billed jaws matches the outer diameter of the cartridge's core. The tool's bills lock on the inner core of the cartridge. Ideally the inner core and outer sleeve will both be extracted with the tool's bills. When conditions are not ideal due to hardened or broken o-rings and corrosion, rotating the tool and cartridge are required to free them from the valve body. The Pasco stem and cartridge puller attached to the screw end of the vise-grips is used to extract the outer sleeve of the cartridge after the inner core has been removed.
