How to Install a Bathroom Faucet Cartridge
A bathroom faucet cartridge is a crucial component that controls the flow of water and temperature in your sink or shower. When it malfunctions, you may experience issues like leaks, dripping, or difficulty regulating water temperature. Replacing a faucet cartridge is a relatively simple task that can be completed by most homeowners with basic tools and a bit of know-how. Here's a step-by-step guide to help you through the process:
Step 1: Gather Tools and Materials
Before starting, ensure you have the following tools and materials:
- New faucet cartridge
- Adjustable wrench
- Allen wrench (if required)
- Pliers
- Bucket or bowl
- Cloth or paper towels
Step 2: Shut Off Water Supply
Locate the shut-off valves under the sink or behind the shower valve. Turn both valves clockwise to cut off the water supply. This step prevents water from spraying when you remove the old cartridge.
Step 3: Remove Decorative Cap
Most faucets have a small decorative cap covering the handle screws. Use a screwdriver or Allen wrench to remove the cap.
Step 4: Remove Handle Screws
Under the decorative cap, you'll find screws securing the handle to the stem. Use a screwdriver to remove these screws.
Step 5: Remove Handle
Once the screws are removed, carefully pull the handle straight up to detach it from the stem.
Step 6: Remove Cartridge Nut
Below the handle, you'll see a cartridge nut. Use an adjustable wrench to loosen and remove the nut.
Step 7: Remove Old Cartridge
Once the cartridge nut is removed, you can pull out the old cartridge. It may be stuck, so use pliers to gently grip and pull it straight up.
Step 8: Inspect Stem
Before installing the new cartridge, inspect the stem for any damage or corrosion. If the stem is damaged, it may need to be replaced as well.
Step 9: Install New Cartridge
Align the new cartridge with the stem and insert it straight down. Push it in until it seats firmly.
Step 10: Install Cartridge Nut
Hand-tighten the cartridge nut onto the stem and then use an adjustable wrench to further tighten it. Avoid overtightening.
Step 11: Reinstall Handle
Place the handle back onto the stem and secure it with the screws removed earlier. Tighten the screws just enough to secure the handle.
Step 12: Install Decorative Cap
Replace the decorative cap over the handle screws.
Step 13: Turn on Water Supply
Go back to the shut-off valves and turn them counterclockwise to restore the water supply.
Step 14: Test Faucet
Operate the faucet to ensure it's working correctly. Check for any leaks or dripping. Adjust the cartridge or tighten connections as needed.
Additional Tips
Here are a few additional tips to keep in mind:
- Replace the cartridge with a genuine part from the faucet manufacturer to ensure compatibility.
- If you encounter any difficulties during the installation, consult a professional plumber.
- Regular maintenance, including periodic cartridge replacement, can extend the life of your faucet.
