How to Repair a Bathroom Sink Faucet

A leaky bathroom sink faucet can be a nuisance and waste a lot of water. Fortunately, it's often a simple repair that you can do yourself with a few tools and materials. Here's a step-by-step guide on how to repair a bathroom sink faucet:

Tools and Materials

Adjustable wrench
Phillips head screwdriver
Flathead screwdriver
Replacement faucet parts (if necessary)
Rags or towels
Plumber's putty
Bucket

Step-by-Step Instructions

1. Turn Off the Water Supply

Before you start working on the faucet, it's important to turn off the water supply. There are usually two shut-off valves under the sink, one for hot water and one for cold water. Turn both valves clockwise to turn off the water.

2. Remove the Aerator (if present)

Some faucets have an aerator, which is a small attachment at the end of the spout. If your faucet has an aerator, remove it by unscrewing it counterclockwise. You may need to use a wrench to loosen it.

3. Remove the Handle

Next, remove the handle by unscrewing the set screw located on the side or back of the handle. You may need to use a screwdriver or Allen wrench to remove the set screw.

4. Remove the Cartridge

Once the handle is removed, you should see the cartridge. The cartridge is the part that controls the flow of water. Remove the cartridge by pulling it straight up. If the cartridge is stuck, you may need to use a wrench to loosen it.

5. Inspect the Cartridge

Inspect the cartridge for any damage or wear. If the cartridge is damaged, you will need to replace it. You can purchase a replacement cartridge at your local hardware store or home improvement center.

6. Install the New Cartridge (if necessary)

If you are replacing the cartridge, insert the new cartridge into the faucet body. Make sure that the cartridge is properly seated and aligned.

7. Reinstall the Handle

Reinstall the handle by screwing it back onto the faucet body. Tighten the set screw to secure the handle.

8. Reinstall the Aerator (if present)

If your faucet has an aerator, screw it back onto the spout.

9. Turn On the Water Supply

Turn on the water supply valves under the sink to restore water flow to the faucet. Check for any leaks and tighten any loose connections as needed.

10. Test the Faucet

Turn on the faucet and check for proper operation. The water should flow smoothly and without leaks.

Tips

If you are not comfortable replacing the cartridge yourself, you can call a plumber for assistance.
Before you start working on the faucet, spread rags or towels around the sink to catch any water or debris.
When tightening the connections, do not overtighten them, as this could damage the faucet.
If the faucet is still leaking after you have made the repairs, there may be a more serious problem that requires professional attention.

Conclusion

Repairing a bathroom sink faucet is a relatively simple task that can be completed in a few hours with the right tools and materials. By following the steps outlined in this guide, you can save yourself the cost of hiring a plumber and keep your bathroom sink running smoothly.
