Water Dripping From Sink Faucet

Water Dripping From Sink Faucet: Causes and Solutions

A persistent drip from a sink faucet can be more than just an annoyance. It wastes water, increases your utility bills, and can even indicate a more serious plumbing issue. Understanding the causes of a dripping faucet is the first step towards resolving the problem effectively.

Common Causes of a Dripping Faucet

There are several common reasons why a sink faucet might drip. The most frequent culprits are worn-out washers, eroded O-rings, or a faulty cartridge.

Worn-out Washers: In older faucets, a washer made of rubber or plastic is responsible for sealing the water flow when the handle is turned off. Over time, these washers can wear down, harden, or become damaged, leading to leaks.

Eroded O-rings: Faucet cartridges often contain O-rings, small rubber seals that prevent water from escaping around the moving parts. These O-rings can become brittle, cracked, or worn, compromising their sealing ability.

Faulty Cartridge: In newer faucets, a cartridge combines the functions of the washer and the O-rings. If this cartridge malfunctions, it can cause a drip, especially if the faucet is a single-handle model.

Steps to Fix a Dripping Faucet

The solution for a dripping faucet depends on its specific cause. Here are some common solutions:

1. Replacing the Washer

For older faucets with separate hot and cold handles, replacing the washer is usually a straightforward fix.

Materials Needed: * Screwdriver * Pliers * Replacement washer (matching the size and type of the original washer)

Instructions: 1. Turn off the water supply to the faucet. 2. Remove the faucet handle by unscrewing it with a screwdriver. 3. Remove the packing nut underneath the handle. 4. Carefully remove the old washer, taking note of its size and type. 5. Install the new washer in its place. 6. Reassemble the faucet, ensuring the packing nut is securely tightened. 7. Turn the water supply back on and test for leaks.

2. Replacing the O-ring

If the O-ring is worn or damaged, replacing it is usually a quick fix.

Materials Needed: * Screwdriver * Pliers * Replacement O-ring (matching the size and type of the original O-ring)

Instructions: 1. Turn off the water supply to the faucet. 2. Remove the faucet handle and any decorative caps. 3. Identify the O-ring location (usually within the cartridge or stem). 4. Use pliers to gently remove the old O-ring. 5. Install the new O-ring in its place, ensuring it is properly seated. 6. Reassemble the faucet and turn the water supply back on.

3. Replacing the Cartridge

For newer single-handle faucets, replacing the cartridge is often the best solution.

Materials Needed: * Screwdriver * Replacement cartridge (matching the make and model of the faucet)

Instructions: 1. Turn off the water supply to the faucet. 2. Remove the faucet handle. 3. Locate the cartridge (often visible under the handle). 4. Use a screwdriver to remove the cartridge. 5. Install the new cartridge, ensuring it is properly seated. 6. Reassemble the faucet and turn the water supply back on.

When to Call a Plumber

While these solutions are effective for many dripping faucets, some issues might require professional assistance. If you encounter any of the following, contact a licensed plumber:

The faucet continues to drip after replacing the washer, O-ring, or cartridge.
The faucet is old and difficult to disassemble.
There are signs of corrosion or damage to the faucet components.
The faucet is leaking from areas other than the spout.

By understanding the causes of a dripping faucet and taking the necessary steps to fix it, you can conserve water, save money on your utility bills, and prevent potential plumbing problems.
