How To Fix A Sink Faucet Leak

A leaky faucet is a common plumbing problem that can waste water and increase your utility bills. Fortunately, fixing a leaky faucet is often a simple task that can be completed in a few minutes with just a few tools. ### Step 1: Gather your tools You will need the following tools to fix a leaky faucet: * Adjustable wrench * Phillips screwdriver * Flathead screwdriver * Allen wrench (if necessary) * Replacement washers or O-rings (if necessary) ### Step 2: Turn off the water supply The first step is to turn off the water supply to the faucet. 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 attached to the end of the faucet. It helps to create a steady stream of water and can become clogged with minerals over time. To remove the aerator, simply unscrew it by hand. ### 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 Allen bolt. Use the appropriate screwdriver or Allen wrench to remove the screw or bolt. ### Step 5: Remove the cartridge or stem The cartridge or stem is the part of the faucet that controls the flow of water. To remove the cartridge or stem, use an adjustable wrench to loosen the packing nut. Once the packing nut is loose, you can pull the cartridge or stem out of the faucet. ### Step 6: Inspect the washer or O-ring The washer or O-ring is a small rubber gasket that creates a seal between the cartridge or stem and the faucet body. Over time, the washer or O-ring can become worn or damaged, causing a leak. Inspect the washer or O-ring for any damage. If the washer or O-ring is damaged, it will need to be replaced. ### Step 7: Replace the washer or O-ring If the washer or O-ring is damaged, you will need to replace it. To do this, simply remove the old washer or O-ring and replace it with a new one. Make sure that the new washer or O-ring is the correct size and type for your faucet. ### Step 8: Reassemble the faucet Once you have replaced the washer or O-ring, you can reassemble the faucet. To do this, simply insert the cartridge or stem back into the faucet body and tighten the packing nut. Then, reattach the handle and aerator. ### Step 9: Turn on the water supply Once the faucet is reassembled, turn on the water supply and check for leaks. If there are no leaks, then you have successfully fixed the leaky faucet.
