This Sloan WES-7 (Part 1001502) T-bar cartridge removal tool/key is made of solid steel and makes it easy to install and replace Sloan universal waterfree urinal cartridges. The T-bar handle provides good leverage for removing a used cartridge. Simply insert the two prongs of the key into the matching holes on the top of the cartridge, turn left to unlock, lift, drain, and then dispose of the cartridge according to the manufacturer's instructions. After sanitizing the urinal fixture, insert a new cartridge into the housing, turn the key right until the cartridge clicks and locks into place; then follow the instructions for adding clean water and sealant to the system. The Sloan Valve Company has been committed to designing and manufacturing innovative, reliable, high-quality plumbing products that conserve water and energy since it began in 1906.
