Drip. Drip. Drip. That incessant sound can drive anyone crazy, especially when it's coming from a leaky faucet. Beyond the annoyance, a dripping faucet wastes water and can lead to higher water bills. Fortunately, many common faucet issues are easily fixable with a bit of know-how and a few basic tools. This guide will walk you through common faucet problems, how to diagnose them, and provide step-by-step instructions for repairing them. We'll also cover preventative maintenance to keep your faucets in top shape and avoid future leaks.
Diagnosing Your Faucet Problem
Before you can fix a faucet, you need to understand what's causing the leak. Different types of faucets have different mechanisms, and therefore, different potential problems. Here's a breakdown of common faucet types and their typical issues:
Compression Faucets
Compression faucets are the oldest and most common type, recognizable by their two separate handles for hot and cold water. They work by using a rubber washer that compresses against a valve seat to stop the flow of water. Common problems include:
- Dripping from the Spout: This is usually caused by a worn-out or damaged washer. Over time, the constant compression wears down the rubber, preventing a tight seal.
- Leaking Around the Handle: This could indicate a worn-out O-ring or packing nut that needs tightening or replacing.
Actionable Advice: Examine the washer closely. Is it cracked, flattened, or otherwise damaged? Even a slight imperfection can cause a leak. Also, check the valve seat for corrosion or mineral buildup.
Ball Faucets
Ball faucets are known for their single handle that controls both water flow and temperature. They use a slotted ball to regulate water flow. Common problems include:
- Leaking from the Spout: This is often due to worn-out or damaged O-rings and seals within the faucet body.
- Leaking Around the Handle: This can also be caused by loose adjustment rings or a worn-out cam assembly.
Actionable Advice: Ball faucets have many small parts, so it's helpful to have a repair kit specifically designed for your faucet model. Take pictures as you disassemble the faucet to help you reassemble it correctly.
Cartridge Faucets
Cartridge faucets also use a single handle but operate with a cylindrical cartridge that moves up and down to control water flow. Common problems include:
- Dripping from the Spout: This usually means the cartridge itself is damaged or worn out and needs to be replaced.
- Difficulty Controlling Water Temperature: This can also indicate a faulty cartridge.
Actionable Advice: Turn off the water supply before removing the cartridge. Some cartridges can be difficult to remove, so try using a specialized cartridge puller tool.
Ceramic Disc Faucets
Ceramic disc faucets are the most modern type, known for their smooth operation and durability. They use two ceramic discs that slide over each other to control water flow. Common problems include:
- Dripping from the Spout: This is often caused by sediment or mineral deposits affecting the seal between the ceramic discs.
- Reduced Water Flow: Mineral buildup can also restrict water flow.
Actionable Advice: Carefully clean the ceramic discs with a soft cloth and mild vinegar solution to remove any deposits. Avoid using abrasive cleaners that could scratch the discs.
Essential Tools and Materials
Having the right tools and materials on hand will make faucet repair much easier. Here's a basic list:
- Adjustable Wrench: For loosening and tightening nuts and bolts.
- Screwdrivers (Phillips and Flathead): For removing handles and other components.
- Pliers: For gripping and manipulating small parts.
- Allen Wrench Set: For some handle and set screw types.
- Basin Wrench: For reaching tight spaces under the sink.
- Plumber's Tape (Teflon Tape): For sealing threaded connections.
- Penetrating Oil: For loosening stubborn nuts and bolts.
- Replacement Washers, O-rings, and Cartridges: Have a variety of sizes on hand or purchase a faucet repair kit specific to your faucet model.
- Old Towels or Rags: For soaking up water and protecting surfaces.
- Bucket: To catch any water that may spill.
- Vinegar: For cleaning mineral deposits.
Tip: Before starting any repair, shut off the water supply to the faucet. Usually, there are shut-off valves located under the sink. If you can't find them or they're not working, you may need to shut off the main water supply to your house.
Repairing a Leaky Compression Faucet
Let's walk through repairing a leaky compression faucet, as it's one of the most common types.
- Turn Off the Water Supply: Locate the shut-off valves under the sink and turn them clockwise to shut off the water supply. Turn on the faucet to relieve any remaining pressure.
- Remove the Handle: Depending on the faucet, you may need to remove a decorative cap or set screw to access the handle screw. Use a screwdriver or Allen wrench to loosen the screw and remove the handle.
- Remove the Packing Nut: Use an adjustable wrench to loosen and remove the packing nut.
- Remove the Stem: The stem should now be accessible. Unscrew it from the faucet body.
- Remove the Washer: At the bottom of the stem, you'll find the rubber washer. Use a screwdriver or small tool to pry it off.
- Inspect the Valve Seat: Examine the valve seat inside the faucet body for any corrosion or damage. If necessary, use a valve seat wrench to remove and replace it. You can also try cleaning it with a valve seat dressing tool.
- Replace the Washer: Install a new washer of the same size and type onto the stem.
- Reassemble the Faucet: Reassemble the faucet in reverse order. Screw the stem back into the faucet body, tighten the packing nut, and reattach the handle.
- Turn On the Water Supply: Slowly turn on the water supply and check for leaks. If the faucet is still leaking, double-check the washer and valve seat.
Practical Example: I had a compression faucet that was dripping incessantly. After following these steps, I discovered that the washer was completely flattened and cracked. Replacing it with a new washer instantly stopped the leak.

Repairing Other Faucet Types
While the basic principles are the same, repairing ball, cartridge, and ceramic disc faucets involves slightly different steps.
Ball Faucets
- Shut off the Water Supply.
- Loosen the Set Screw: Use an Allen wrench to loosen the set screw on the side of the handle.
- Remove the Handle and Cap: Lift off the handle and unscrew the cap.
- Loosen the Adjustment Ring: Use a special wrench (often included in repair kits) to loosen the adjustment ring.
- Remove the Ball and Stem Assembly: Lift out the ball and stem assembly.
- Replace O-rings and Seals: Replace any worn or damaged O-rings and seals. A repair kit usually includes all the necessary replacements.
- Reassemble the Faucet: Reassemble the faucet in reverse order, making sure the ball is properly aligned.
Cartridge Faucets

Extending Faucet Lifespan: Maintenance Tips
Preventative maintenance is key to extending the lifespan of your faucets and avoiding costly repairs. Here are some tips:
- Regular Cleaning: Clean your faucets regularly with a mild soap and water solution. Avoid using abrasive cleaners that can damage the finish.
- Inspect for Leaks: Periodically check your faucets for leaks, even small ones. Addressing leaks early can prevent them from becoming bigger problems.
- Lubricate Moving Parts: Lubricate moving parts, such as handles and stems, with a silicone-based lubricant to keep them operating smoothly.
- Check Water Pressure: High water pressure can put stress on your faucets and cause them to wear out faster. Consider installing a pressure regulator to maintain a consistent water pressure. According to the EPA, water pressure should be between 40 and 60 psi.EPA Water Pressure Guide
- Consider a Water Softener: If you have hard water, consider installing a water softener to reduce mineral buildup in your faucets and pipes. Hard water contains high levels of minerals like calcium and magnesium, which can cause scaling and corrosion.
Tip: When replacing washers or O-rings, always use high-quality replacements. Cheap parts may not last as long and could cause more problems down the road.
When to Call a Plumber
While many faucet repairs are DIY-friendly, there are times when it's best to call a licensed plumber. Consider calling a plumber if:
- You're not comfortable working with plumbing.
- You've tried to fix the faucet yourself and it's still leaking.
- You encounter more complex problems, such as corroded pipes or damaged valve seats.
- You're dealing with a major plumbing issue that could cause water damage to your home.
Note: Ignoring plumbing problems can lead to more serious damage and higher repair costs in the long run. It's always better to err on the side of caution and call a professional if you're unsure.
