Shut Off Water Supply
Locate the water shut-off valves under your kitchen sink. Turn them clockwise to close and stop water flow. Sometimes, there might be a main water valve near your home’s water meter. Close this valve if you cannot find shut-off valves under the sink. Open the faucet to release any water left in the pipes. This step prevents water from spilling when you remove the faucet cartridge. Use a cloth to soak up any water that drips out. Ensure the water supply is completely off before proceeding with the cartridge change.
Remove The Faucet Handle
Locate the small set screw on the faucet handle. Use an Allen wrench or screwdriver to loosen this screw carefully. Gently pull the handle straight up to remove it. Sometimes, the handle may stick; wiggle it slightly to loosen. Keep the screw safe for reassembly. Removing the handle reveals the cartridge underneath. This step is key to accessing the cartridge for replacement or repair.

Extract The Old Cartridge
Start by turning off the water supply under the sink. This stops water flow and prevents spills. Open the faucet to release any leftover water inside.
Next, use a wrench to remove the retaining nut. This holds the cartridge in place. Be gentle to avoid breaking any parts.
Pull out the old cartridge straight up. If it feels stuck, wiggle it gently to loosen. Check for any debris or buildup in the faucet body.
- Keep a towel handy for any drips.
- Note the cartridge’s position before removal.

Install The New Cartridge And Reassemble
Place the new cartridge carefully into the faucet body. Make sure it fits snugly and aligns with the slots. Tighten the retaining clip or nut to hold the cartridge in place. Do not overtighten to avoid damage.
Reattach the handle and secure it with the screw. Replace any decorative caps or covers. Turn the water supply back on slowly and check for leaks. Test the faucet by turning it on and off to ensure smooth operation.
