Troubleshooting Common Problems

First, you need to identify the problem with your faucet. Here are a few common issues and their potential causes:

Leaking from the base: This can be caused by a faulty O-ring or a loose connection at the base of the faucet.
Handle is loose or difficult to turn: This may indicate worn-out or damaged cartridge or loose handle screws.
Reduced water flow: Clogged aerator or a buildup of debris in the faucet lines could be the culprit.

Turn off the water supply and open the faucet to release any remaining water.
用扳手松开固定在水龙头底座上的螺母。

If the O-ring is damaged, replace it with a new one.
Apply a thin layer of plumber's putty around the base of the faucet.

Replacing a Cartridge

To replace a cartridge, follow these steps:

Remove the handle of the faucet by using an Allen wrench or hex key to unlock the set screw.
Use an adjustable wrench to loosen the retaining nut that holds the cartridge in place.

Install the new cartridge by inserting it into the faucet body and aligning the splines.
Tighten the retaining nut securely.
Reinstall the handle and tighten the set screw.

Cleaning a Clogged Aerator

To clean a clogged aerator, follow these steps:
