How To Change Cartridge In Bathroom Sink Faucet

How to Change a Cartridge in a Bathroom Sink Faucet

A leaky faucet can be a frustrating waste of water, but it doesn't have to be an expensive fix. In many cases, you can replace the cartridge in the faucet yourself in just a few minutes. Here's how:

Step 1: Turn off the water supply

Locate the shutoff valves under the sink and turn them off. If there are no shutoff valves, you'll need to turn off the main water supply to the house before proceeding.

Step 2: Remove the old cartridge

Most cartridges are held in place by a small screw or cap. Use a screwdriver or wrench to remove the screw or cap, then pull the cartridge straight out of the faucet body.

Step 3: Inspect the cartridge

Once the cartridge is removed, inspect it for any damage. If the cartridge is cracked or damaged, it will need to be replaced.

Step 4: Insert the new cartridge

Insert the new cartridge into the faucet body. Make sure that the cartridge is aligned correctly and that the o-rings are properly seated.

Step 5: Tighten the screw or cap

Replace the screw or cap that holds the cartridge in place. Tighten the screw or cap until it is snug, but do not overtighten.

Step 6: Turn on the water supply

Turn on the shutoff valves or the main water supply to the house. Check for any leaks and make any necessary adjustments.
