How To Replace Delta Single Handle Kitchen Faucet Cartridge

Delta single handle kitchen faucets are popular for their durability and ease of use. However, over time, the cartridge inside the faucet may wear out or become faulty, leading to leaks or difficulty in controlling water flow. In such cases, it becomes necessary to replace the cartridge to restore the faucet’s functionality. This article will guide you through the process of replacing the Delta single handle kitchen faucet cartridge, providing step-by-step instructions and valuable insights.

Step 1: Gather the necessary tools and materials

Before starting the replacement process, it is essential to gather all the required tools and materials. Here’s a list of items you will need:

• Adjustable wrench
• Phillips screwdriver
• Replacement cartridge
• Plumber’s grease
• Towel or rag

Step 2: Turn off the water supply

Before working on any plumbing fixture, it is crucial to turn off the water supply to avoid any accidents or water damage. Locate the shut-off valves under the sink and turn them clockwise until they are fully closed. To ensure the water is completely off, turn on the faucet and let any remaining water drain out.

Step 3: Remove the handle

The handle of the Delta single handle kitchen faucet is usually held in place by a small set screw. Use a Phillips screwdriver to loosen and remove the set screw, which is typically located on the side or underneath the handle. Once the set screw is removed, gently pull the handle off the faucet.

Step 4: Remove the bonnet nut

Underneath the handle, you will find a bonnet nut that holds the cartridge in place. Use an adjustable wrench to loosen and remove the bonnet nut by turning it counterclockwise. It may require some force, so be careful not to damage the surrounding parts.

Step 5: Remove the old cartridge

Once the bonnet nut is removed, you can now take out the old cartridge. Grasp the cartridge firmly and pull it straight out of the faucet body. If it is stuck, you can use pliers to help with the removal. Be cautious not to damage any other components while removing the cartridge.

Step 6: Install the new cartridge

Apply a thin layer of plumber’s grease to the O-rings of the new cartridge to ensure a smooth installation and prevent leaks. Insert the new cartridge into the faucet body, aligning it properly. Push it in firmly until it sits flush with the faucet body.

Step 7: Reassemble the faucet

Once the new cartridge is in place, reassemble the faucet by following the previous steps in reverse order. Start by screwing the bonnet nut back onto the faucet body, tightening it with an adjustable wrench. Then, slide the handle back onto the faucet stem and secure it with the set screw using a Phillips screwdriver.

Step 8: Turn on the water supply

After reassembling the faucet, it’s time to turn the water supply back on. Slowly open the shut-off valves under the sink by turning them counterclockwise. Check for any leaks around the faucet and handle. If you notice any leaks, tighten the connections or replace any faulty parts.
