Step 1
Turn off the water to the Wolverine faucet by closing both the hot and cold water valves under the sink.
Step 2
Take the cap out of the top of the faucet handle with the end of a screwdriver. Unscrew the small screw on the top of the handle with an Allen wrench and pull the handle off the base of the faucet.
Step 3
Take the cartridge cap off the base of the faucet by unscrewing it by hand, or with a pair of channel pliers. Remove the stem O-ring, cartridge valve and cartridge by lifting them out of the faucet base.
Step 4
Insert a new cartridge, valve and O-ring in place of the one you just removed. Replace the cartridge cap and tighten it with the pliers. This secures the cartridge parts in the faucet base.
Step 5
Put the handle on the stem and insert and tighten the screw with the Allen wrench. Replace the cap.
