How To Fix A Leaky Sink Faucet

A leaky faucet is a common household problem that can waste water and increase your water bill. Fortunately, it is usually a relatively easy fix that you can do yourself with a few simple tools. Here are the steps on how to fix a leaky sink faucet:

Step 1: Gather your tools

You will need the following tools to fix a leaky sink faucet: - Adjustable wrench - Phillips head screwdriver - Flat head screwdriver - Allen wrench (if necessary) - New O-rings or washers (if necessary)

Step 2: Turn off the water supply

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

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, unscrew it counterclockwise 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. Most handles are held in place by a screw or a set screw. To remove a handle with a screw, simply unscrew it with a screwdriver. To remove a handle with a set screw, use an Allen wrench to loosen the set screw, then pull the handle off.

Step 5: Remove the cartridge or stem

Once the handle is removed, you will see the cartridge or stem. The cartridge or stem is the part that controls the flow of water through the faucet. To remove the cartridge or stem, use an adjustable wrench to loosen the nut that holds it in place. Once the nut is loose, you can pull the cartridge or stem out of the faucet.

Step 6: Inspect the O-rings or washers

The O-rings or washers are small, rubber gaskets that create a seal between the cartridge or stem and the faucet body. Over time, these O-rings or washers can wear out or become damaged, which can cause the faucet to leak. Inspect the O-rings or washers for any signs of wear or damage. If the O-rings or washers are worn out or damaged, you will need to replace them.

Step 7: Reassemble the faucet

Once you have replaced the O-rings or washers, you can reassemble the faucet. To reassemble the faucet, simply reverse the steps that you took to disassemble it. First, insert the cartridge or stem into the faucet body. Then, tighten the nut that holds the cartridge or stem in place. Next, reattach the handle. Finally, reattach the aerator.

Step 8: Turn on the water supply

Once the faucet is reassembled, you can turn on the water supply. Check the faucet for any leaks. If the faucet is still leaking, you may need to tighten the nut that holds the cartridge or stem in place more.
