To remove a faucet cartridge, you'll generally need to first remove the handle and any retaining clips or nuts, and then pull the cartridge out using pliers or your fingers.
Here's a more detailed breakdown:
-
Turn Off the Water Supply: Before starting any plumbing work, turn off the water supply to the faucet. This is usually done via shut-off valves located under the sink.
-
Remove the Faucet Handle: How you remove the handle depends on the faucet type. Look for a set screw (often hidden under a decorative cap) that you need to loosen with an Allen wrench. Once loosened, the handle should pull off. Some handles might simply unscrew.
-
Remove Retaining Clip or Nut: Once the handle is off, you'll likely see a retaining clip or nut holding the cartridge in place. Remove this clip or unscrew the nut. The clip may require a small screwdriver or pliers to remove.
-
Pull Out the Cartridge: With the retaining clip or nut removed, the cartridge should now be free to pull out. Use pliers or your fingers to grip the cartridge firmly and pull it straight out. Sometimes, the cartridge can be stiff or stuck due to mineral buildup. If this happens, try gently wiggling the cartridge back and forth while pulling.
Troubleshooting:
-
Stuck Cartridge: If the cartridge is difficult to remove, try using a cartridge puller tool. These tools are specifically designed to grip and remove stubborn cartridges. You can also try soaking the area around the cartridge with vinegar to help dissolve mineral buildup.
-
Broken Cartridge: If the cartridge breaks during removal, use needle-nose pliers to carefully extract any remaining pieces.
Important Considerations:
- Faucet Type: Cartridge removal procedures can vary slightly depending on the faucet type (e.g., single-handle, double-handle, ceramic disc, ball-type).
- Replacement: Before removing the old cartridge, take note of its orientation so you can install the new one correctly. It's also helpful to take the old cartridge with you to the hardware store to ensure you get the correct replacement.
