How To Fix A Leaking Bathroom Faucet

A leaking bathroom faucet is a common problem that can waste water and increase your water bill. If you're not sure how to fix a leaking bathroom faucet, don't worry – it's actually a relatively easy task that you can do yourself with a few simple tools. Here's a step-by-step guide on how to fix a leaking bathroom faucet:

Step 1: Gather your tools

You will need the following tools to fix a leaking bathroom faucet:

Adjustable wrench
Allen wrench
Phillips head screwdriver
Flat head screwdriver
Replacement faucet washer
Plumber's putty
Rags

Step 2: Turn off the water supply

Before you start working on the faucet, you need to turn off the water supply. There will be two shut-off valves under the sink, one for the hot water and one for the cold water. Turn both of these valves clockwise to turn off the water supply.

Step 3: Remove the aerator

The aerator is the small, screen-like attachment at the end of the faucet. It helps to aerate the water and reduce splashing. To remove the aerator, simply unscrew it by hand. If the aerator is stuck, you can use a pair of pliers to gently loosen it.

Step 4: Remove the handle

Once the aerator is removed, you can remove the handle. There will be a small screw on the top of the handle. Remove this screw and then pull the handle straight up to remove it.

Step 5: Remove the cartridge

The cartridge is the part of the faucet that controls the flow of water. To remove the cartridge, you will need to use an Allen wrench. Insert the Allen wrench into the hole in the center of the cartridge and turn it counterclockwise to loosen the cartridge. Once the cartridge is loose, you can pull it straight out.

Step 6: Inspect the cartridge and replace the washer

Once the cartridge is removed, you can inspect it for damage. If the washer is worn or damaged, you will need to replace it. To replace the washer, simply remove the old washer and replace it with a new one. Make sure that the new washer is the same size and shape as the old one.

Step 7: Reassemble the faucet

Once you have replaced the washer, you can reassemble the faucet. To do this, simply insert the cartridge back into the faucet and tighten it with the Allen wrench. Then, replace the handle and tighten the screw. Finally, screw the aerator back onto the faucet.

Step 8: Turn on the water supply and test the faucet

Once the faucet is reassembled, you can turn on the water supply and test the faucet. If the faucet is still leaking, you may need to adjust the packing nut. The packing nut is located at the base of the faucet. To adjust the packing nut, simply tighten it with a wrench. Be careful not to overtighten the packing nut, as this can damage the faucet.
