Repairing Single Lever Bathroom Faucet

In-Depth Guide to Repairing a Single Lever Bathroom Faucet

When your single lever bathroom faucet starts to act up, it can be a frustrating experience. Before calling a plumber, consider tackling the repair yourself. With the right tools and a bit of know-how, you can get the job done promptly and save some money. ### Essential Tools for the Repair: - Phillips head screwdriver - Flathead screwdriver - Allen wrench - Adjustable wrench - Plumber's putty - New faucet cartridge (if necessary) ### Troubleshooting & Repair Steps: 1.

Turn Off the Water Supply:

Before beginning any work, locate the shut-off valves under the sink and turn them off to prevent water from flowing. 2.

Identify the Issue:

Determine the source of the problem by testing the water flow and checking for leaks. Common issues include a worn-out cartridge, loose handles, or a faulty aerator. 3.

Remove the Handle:

Use the appropriate screwdriver to remove the handle set screws and lift off the handle. 4.

Unscrew the Cartridge Retainer Nut:

Using an adjustable wrench, carefully unscrew the cartridge retainer nut located under the handle. 5.

Pull Out the Cartridge:

Once the nut is removed, gently pull out the old cartridge. Avoid twisting or pulling too hard. 6.

Replace the Cartridge (if needed):

If the cartridge is defective, you will need to replace it with a new one. Align the flats on the new cartridge with the splines in the faucet body and insert it firmly. 7.

Lubricate and Install the Cartridge Retainer:

Apply a thin layer of plumber's putty around the base of the retainer nut and install it, tightening it securely. 8.

Replace the Handle:

Slide the handle back onto the faucet and secure it with the handle set screws. 9.

Turn On the Water Supply:

Slowly turn on the shut-off valves and check for any leaks. If there are no leaks, you have successfully repaired the faucet. ### Troubleshooting Tips: - If the faucet still leaks after replacing the cartridge, check the O-rings on the cartridge retainer nut and ensure they are properly seated. - For a dripping aerator, remove it using an adjustable wrench and clean or replace the screen filter. - If the handle is loose, tighten the set screws further. - In case of a major leak or if you are unable to repair the faucet yourself, do not hesitate to call a qualified plumber.
