Water Leaking From Sink Faucet

A leaking sink faucet is a common plumbing problem that can waste water and increase your water bill. There are several potential causes of a leaking sink faucet, including worn-out washers, damaged O-rings, or a faulty cartridge. While some faucet leaks can be fixed with a simple do-it-yourself repair, others may require the assistance of a professional plumber.

Causes of Sink Faucet Leaks

Worn-out washers: Washers are small, rubber or plastic discs that create a seal between the faucet handle and the valve stem. Over time, washers can become worn or damaged, allowing water to leak.
Damaged O-rings: O-rings are small, rubber rings that create a seal between the faucet body and the spout. Damaged O-rings can allow water to leak from the base of the faucet.
Faulty cartridge: Cartridges are the internal components of a faucet that control the flow of water. A faulty cartridge can cause water to leak from the handle or spout of the faucet.
Loose connections: Loose connections between the faucet body and the water supply lines can also cause leaks.

DIY Faucet Leak Repair

If you are comfortable with basic plumbing tasks, you may be able to fix a leaky sink faucet yourself. Here are some steps to follow:

Turn off the water supply: Before you begin any repairs, turn off the water supply to the sink. You can usually do this by turning the shutoff valves located under the sink.
Remove the faucet handle: Most faucet handles are held in place by screws. Remove the screws and lift off the handle.
Replace the washer: If the washer is worn or damaged, replace it with a new one. Make sure to get the right size washer for your faucet.
Replace the O-ring: If the O-ring is damaged, replace it with a new one. Lubricate the O-ring with a small amount of silicone grease before installing it.
Replace the cartridge: If the cartridge is faulty, it will need to be replaced. Follow the manufacturer's instructions for replacing the cartridge.
Tighten loose connections: If the faucet is leaking from loose connections, tighten the connections using a wrench.
Turn on the water supply: Once you have made the repairs, turn on the water supply and check for leaks.

When to Call a Plumber

If you are not comfortable repairing a leaky sink faucet yourself, or if the leak is coming from a more complex problem, it is best to call a professional plumber. A plumber can diagnose the problem and make the necessary repairs quickly and efficiently.
