5 Simple Fixes for a Leaky Kitchen Faucet

A leaky kitchen faucet is more than just an annoying drip - it wastes water and money and can increase utility bills. Fortunately, many common faucet leaks can be fixed without calling a plumber.

Here's a comprehensive guide to help you tackle this common household problem.

Understanding Your Faucet Type

Before attempting any repairs, identify what type of faucet you have. The most common types are:

• Compression faucets (with separate hot and cold handles)
• Ball-type faucets (single handle)
• Cartridge faucets (single or double handle)
• Ceramic disk faucets (single handle)

Each type has different internal components, but the fixes are generally straightforward.

Fix #1: Replacing the O-Ring

A worn-out O-ring is often the culprit when water leaks near the base of the spout. Here's how to fix it:

1. Turn off the water supply under the sink
2. Remove the handle by unscrewing the decorative cap and removing the screw underneath
3. Remove the stem and locate the O-ring
4. Replace the old O-ring with an exact match
5. Reassemble the faucet in reverse order

This simple fix often solves leaks around the handle or base of the spout. Make sure to bring the old O-ring to the hardware store to ensure an exact match.

Fix #2: Replacing the Washer

For compression faucets, a worn rubber washer is typically responsible for drips from the spout. To replace it:

1. Shut off the water supply
2. Remove the handle and stem assembly
3. Unscrew the brass screw holding the washer in place
4. Replace the old washer with a new one of the same size
5. Reassemble all components

Be sure to use the correct size and type of washer. Using the wrong size can cause continued leaking or damage to the valve seat.

Fix #3: Cleaning the Aerator

Sometimes, what appears to be a leak is actually a clogged aerator that causes irregular water flow. Here's how to clean it:

1. Unscrew the aerator from the tip of the faucet spout
2. Disassemble the aerator components
3. Soak all parts in white vinegar for several hours
4. Scrub away mineral deposits with a small brush
5. Rinse thoroughly and reassemble

Regular aerator cleaning can prevent irregular spray patterns and maintain proper water flow.

Fix #4: Replacing the Cartridge

For cartridge-style faucets, a failing cartridge can cause leaks. To replace it:

1. Turn off the water supply
2. Remove the handle and decorative cap
3. Remove the retaining nut and pull out the old cartridge
4. Insert the new cartridge, ensuring proper alignment
5. Reassemble the faucet components

When purchasing a replacement cartridge, note the brand and model of your faucet, as cartridges are typically brand-specific.

Fix #5: Repairing the Valve Seat

A corroded valve seat can cause leaks at the spout. While slightly more complex, this repair is still manageable:

1. Turn off the water supply and remove the handle and stem
2. Use a valve seat wrench to remove the old valve seat
3. Clean the area thoroughly
4. Install the new valve seat
5. Reassemble the faucet

This repair requires a special tool (valve seat wrench) but can significantly extend the life of your faucet.

Essential Tools and Materials

Before starting any repair, gather these items:

• Adjustable wrench
• Phillips and flathead screwdrivers
• Penetrating oil
• Replacement parts (O-rings, washers, cartridge)
• Plumber's grease
• Clean rags
• A bucket or towel to catch water

When to Call a Professional

While these fixes are generally straightforward, some situations warrant professional help:

• Extensive corrosion or damage
• Cracked faucet body
• Damaged water lines
• Leaks inside walls
• Multiple repair attempts without success

Preventive Maintenance Tips

To avoid future leaks:

• Don't overtighten handles
• Clean mineral deposits regularly
• Address small leaks promptly
• Use faucets gently
• Perform annual maintenance checks

Cost Savings

Fixing a leaky faucet yourself can save significant money:

• DIY repair costs: $10-30 for parts
• Professional plumber: $150-300 per visit
• Water savings: Up to $20 per month on water bills

Environmental Impact

Fixing a leaky faucet isn't just about saving money - it's also about conservation:

• A faucet dripping once per second wastes over 3,000 gallons annually
• Fixing leaks reduces water treatment facility burden
• Conserving water helps protect natural resources

A leaky kitchen faucet doesn't always require professional intervention. With basic tools, the right replacement parts, and careful attention to detail, you can often fix the problem yourself.
