How To Repair Dripping Sink Faucet

A dripping sink faucet is a common plumbing problem that can waste water and increase your water bill. It can also be annoying, especially if the drip is constant. Fortunately, fixing a dripping sink faucet is usually a relatively easy and inexpensive repair that you can do yourself. ### Tools and Materials You'll Need * Adjustable wrench * Phillips head screwdriver * Flat head screwdriver * Plumber's putty * Replacement faucet washer(s) * Replacement O-rings (if necessary) ### Step-by-Step Instructions 1.

Turn off the water supply.

There should be two shut-off valves under the sink, one for the hot water and one for the cold water. Turn both valves clockwise until the water is completely shut off. 2.

Open the faucet.

This will release any remaining water from the faucet and make it easier to work on. 3.

Remove the aerator.

The aerator is the small, screen-like attachment at the end of the faucet. It can usually be removed by hand, but if it's stuck, you can use a wrench. 4.

Remove the handle.

The handle is usually held in place by a screw. Use a Phillips head screwdriver to remove the screw and then pull the handle off. 5.

Remove the packing nut.

The packing nut is located where the faucet handle was attached. Use an adjustable wrench to loosen the packing nut and then remove it by hand. 6.

Remove the stem.

The stem is the metal rod that extends from the faucet body. Use a flat head screwdriver to pry the stem out of the faucet body. 7.

Inspect the washer and O-rings.

The washer is a small, rubber washer that sits on the end of the stem. The O-rings are small, rubber rings that seal the stem against the faucet body. If the washer or O-rings are worn or damaged, they need to be replaced. 8.

Replace the washer and O-rings.

If the washer or O-rings need to be replaced, apply a small amount of plumber's putty to the new washer or O-rings. Then, insert the new washer or O-rings into the faucet body. 9.

Reassemble the faucet.

Reassemble the faucet in the reverse order of disassembly. Be sure to tighten the packing nut securely. 10.

Turn on the water supply.

Slowly turn on the water supply valves under the sink. Check for leaks. If there are no leaks, your faucet repair is complete. ### Tips * If you're not sure what type of washer or O-rings you need, take the old ones to a hardware store and ask for help. * If the drip is coming from the base of the faucet, it may be necessary to replace the faucet cartridge. * If you're not comfortable making this repair yourself, you can call a plumber for assistance.
