Step-by-step tutorial: replace your kitchen faucet cartridge like a pro

If you’re experiencing leaky faucets or reduced water pressure, replacing the kitchen faucet cartridge is often the solution. This comprehensive guide will walk you through every step of the process, empowering you to tackle this plumbing task like a pro.

Tools and Materials You’ll Need:

• Adjustable wrench
• Phillips screwdriver
• Cartridge puller (optional)
• New faucet cartridge
• Plumber’s putty
• Rags or towels

Step 1: Identify Your Faucet Type

Determine the type of faucet you have. There are two main types: disc cartridge faucets and compression faucets. Disc cartridge faucets have a single handle that controls both water flow and temperature, while compression faucets have two separate handles for hot and cold water.

Step 2: Shut Off Water Supply

Locate the shut-off valves under the sink and turn them clockwise to close them. This will prevent water from flowing into the faucet while you replace the cartridge.

Step 3: Remove the Faucet Handle

For disc cartridge faucets, use a screwdriver to remove the handle cap. For compression faucets, remove the handle screw and lift the handle off.

Step 4: Remove the Cartridge Retainer Nut

Locate the cartridge retainer nut, which is usually a large plastic or metal nut located beneath the handle. Use an adjustable wrench to loosen and remove the nut.

Step 5: Extract the Old Cartridge

There are two ways to extract the old cartridge. If you have a cartridge puller, insert it into the cartridge and pull it straight up. If you don’t have a puller, use an adjustable wrench to gently pry the cartridge loose.

Step 6: Apply Plumber’s Putty

Apply a thin bead of plumber’s putty around the base of the new cartridge. This will help create a watertight seal.

Step 7: Insert the New Cartridge

Align the new cartridge with the slots in the faucet body and press it firmly into place. Tighten the cartridge retainer nut by hand, then use an adjustable wrench to snug it down.

Step 8: Reinstall the Handle

Reinstall the faucet handle by aligning it with the cartridge stem and pressing it down. For disc cartridge faucets, screw on the handle cap. For compression faucets, tighten the handle screw.

Step 9: Turn On Water Supply

Slowly turn on the shut-off valves to allow water to flow into the faucet. Check for leaks around the cartridge and handle. If there are any leaks, tighten the connections as needed.

Troubleshooting Tips

• If you encounter difficulty removing the cartridge, use a penetrating oil to loosen it.
• If the new cartridge doesn’t fit properly, check the model number of your faucet to ensure you have the correct replacement.
• If the faucet still leaks after replacing the cartridge, there may be an issue with the faucet body or other components. Contact a plumber for assistance.
