A dripping faucet might seem like a minor annoyance, but those persistent drops can quietly inflate your water bill and potentially lead to bigger plumbing problems down the line. According to the EPA, household leaks can waste nearly 1 trillion gallons of water annually nationwide. That's enough water to supply more than 11 million homes! Addressing a dripping faucet promptly not only saves water and money but also prevents potential damage to your fixtures and surrounding areas. Whether you're a seasoned DIY enthusiast or a first-time homeowner, this guide will equip you with the knowledge and confidence to tackle a dripping faucet and restore peace (and dryness) to your home. Let's dive in!
Identifying the Type of Faucet
Before you grab your tools, it's crucial to identify the type of faucet you're dealing with. Faucets come in various designs, and understanding the mechanism behind yours will simplify the repair process. The four main types are:
- Compression Faucets: These are the oldest and most common type, easily recognizable by their two separate handles for hot and cold water. They work by using a stem-type valve with a rubber washer at the end. Turning the handle compresses the washer against the valve seat, stopping the water flow.
- Ball Faucets: Typically found in kitchens, ball faucets feature a single handle that controls both the water flow and temperature. The handle operates a ball mechanism inside the faucet body.
- Cartridge Faucets: Similar to ball faucets, cartridge faucets also use a single handle. However, instead of a ball, they employ a cartridge that moves up and down to control water flow.
- Ceramic Disc Faucets: These are the most modern and generally the most expensive type. They are easily identified by their single lever handle on top of a wide cylindrical body. They use two ceramic discs that slide over each other to control water flow.
Once you've identified your faucet type, you can find specific repair instructions that match its design.
Gathering Your Tools and Materials
Having the right tools and replacement parts on hand before you start is essential for a smooth repair. Here's a basic checklist:
- Adjustable Wrench: For loosening and tightening nuts and bolts.
- Screwdrivers: Both flathead and Phillips head screwdrivers in various sizes.
- Pliers: Regular and needle-nose pliers for gripping and manipulating small parts.
- Allen Wrench Set: For removing handles and stems in some faucet types.
- Penetrating Oil: To loosen stubborn nuts and bolts.
- Plumber's Grease: To lubricate faucet parts during reassembly.
- Old Rags or Towels: To protect surfaces and clean up spills.
- Basin Wrench: Helpful for reaching nuts in tight spaces under the sink.
- Replacement Parts: This will depend on the faucet type and the suspected cause of the leak. Common replacement parts include:
- Washers (for compression faucets)
- O-rings
- Cartridges
- Valve seats
- Faucet handles
Tip: Before heading to the hardware store, take the old parts with you to ensure you get the correct replacements.
Step-by-Step Repair Guide for Common Faucet Types
Now, let's delve into the repair process for each faucet type. Remember to always turn off the water supply before starting any repairs!
Repairing a Compression Faucet
- Turn off the water supply: Locate the shut-off valves under the sink and turn them clockwise to close. If you don't have individual shut-off valves, turn off the main water supply to your house.
- Protect the sink: Cover the sink with a towel or cloth to prevent scratches.
- Remove the handle: Depending on the faucet, you may need to pry off a decorative cap on the handle to reveal a screw. Remove the screw and pull off the handle.
- Loosen the packing nut: Use an adjustable wrench to loosen the packing nut that holds the stem in place.
- Remove the stem: Unscrew the stem from the faucet body.
- Replace the washer: At the end of the stem, you'll find a rubber washer held in place by a screw. Remove the screw and replace the old washer with a new one. Make sure the new washer is the same size and shape as the old one.
- Inspect the valve seat: The valve seat is the part of the faucet body that the washer presses against. If it's corroded or damaged, it can cause leaks. You can often remove the valve seat with a special valve seat wrench. If it's not removable, you can try cleaning it with a valve seat dressing tool.
- Replace O-rings: Check the stem for any O-rings and replace them if they look worn or damaged.
- Reassemble the faucet: Apply plumber's grease to the threads of the stem and the inside of the packing nut. Reinsert the stem into the faucet body and tighten the packing nut. Replace the handle and secure it with the screw.
- Turn on the water supply: Slowly turn on the water supply and check for leaks. If the faucet still drips, tighten the packing nut slightly.
Repairing a Ball Faucet
- Turn off the water supply: As with all faucet repairs, start by turning off the water supply.
- Remove the handle: Loosen the set screw on the side of the handle with an Allen wrench and pull off the handle.
- Loosen the adjusting ring: Use a special wrench or pliers to loosen the adjusting ring.
- Remove the cap and ball: Lift off the cap and the ball mechanism.
- Inspect the parts: Examine the ball, springs, and seats for wear or damage. Replace any worn parts.
- Replace the O-rings and springs: Use a small screwdriver or pick to remove the old O-rings and springs. Install the new O-rings and springs in their proper positions.
- Reassemble the faucet: Place the ball back into the faucet body, followed by the cap and adjusting ring. Tighten the adjusting ring with the wrench or pliers. Replace the handle and secure it with the set screw.
- Turn on the water supply: Slowly turn on the water supply and check for leaks. Adjust the adjusting ring if necessary to stop any leaks.
Repairing a Cartridge Faucet
- Turn off the water supply: Turn off the water supply before starting.

Troubleshooting Common Issues
Sometimes, even after replacing parts, the faucet might still drip. Here are some common issues and their solutions:
- Still dripping after replacing the washer (compression faucet): The valve seat may be corroded or damaged. Try cleaning it with a valve seat dressing tool or replacing it if possible.
- Dripping from the base of the faucet: The O-rings on the faucet body may be worn. Replace the O-rings.
- Low water pressure: The aerator may be clogged with sediment. Unscrew the aerator and clean it.
- Noisy faucet: The water pressure may be too high. Install a pressure-reducing valve on the main water supply line.
Preventative Maintenance Tips
Regular maintenance can prevent future leaks and extend the life of your faucets. Here are some helpful tips:
- Clean aerators regularly: Mineral buildup in aerators can restrict water flow and cause leaks. Unscrew and clean them every few months.
- Lubricate faucet parts: Apply plumber's grease to faucet stems and O-rings during repairs to keep them moving smoothly and prevent wear.
- Avoid overtightening: Overtightening handles and nuts can damage faucet parts and cause leaks. Tighten only until snug.
- Inspect faucets regularly: Check for leaks and drips periodically. Address any issues promptly to prevent them from worsening.
- Consider water softeners: Hard water can cause mineral buildup and corrosion in faucets. A water softener can help prevent these problems. According to the Water Quality Research Foundation, water softeners can extend the lifespan of plumbing fixtures and appliances.
