Drip, Drip, Stop! A Comprehensive Guide to Fixing a Leaky Faucet

That incessant drip, drip, drip from a leaky faucet can be incredibly annoying. Beyond the auditory torture, it’s also a significant waste of water and a drain on your wallet. Fortunately, fixing a leaky faucet is often a DIY project that you can tackle with a bit of patience and the right tools. This comprehensive guide will walk you through the process, step-by-step, covering various faucet types and potential issues. So, put on your handy hat, and let’s stop that leak!

Understanding Your Faucet

Before diving into repairs, it’s crucial to understand the basic mechanics of your faucet and identify its type. Faucets generally fall into four main categories:

• Compression Faucets: These are the oldest and simplest type. They typically have two separate handles for hot and cold water. They use rubber washers and a compression mechanism to stop the flow of water.
• Cartridge Faucets: These faucets have a single handle that controls both water temperature and flow. They use a cartridge – a cylinder with holes – to regulate water.
• Ball Faucets: Also using a single handle, these faucets employ a ball mechanism inside the spout to control water flow and temperature.
• Ceramic Disc Faucets: Modern and sleek, these faucets have a single handle and utilize two ceramic discs that slide over each other to regulate water.

Knowing your faucet type will help you diagnose the problem and determine the appropriate repair method.

Gathering Your Tools and Materials

Having the right tools on hand makes the repair process much smoother. Here’s a list of what you’ll likely need:

• Adjustable Wrench: For loosening and tightening nuts and connections.
• Basin Wrench: Particularly useful for reaching nuts in tight spots, especially under the sink.
• Screwdrivers (Flathead and Phillips): For removing handles, plates, and other components.
• Pliers: For gripping and manipulating small parts.
• Penetrating Oil (WD-40): To help loosen stubborn nuts and bolts.
• Old Towels or Rags: For soaking up water and protecting surfaces.
• Replacement Parts: Based on your faucet type and diagnosis. Common parts include O-rings, washers, cartridges, and valve seats.
• Plumber’s Tape (Teflon Tape): For sealing threaded connections.
• Optional: Flashlight, Small Bucket, Safety Glasses

Before you start, ensure you’ve gathered all the necessary tools and replacement parts. It’s always wise to have a small bucket and towels ready to catch any water spillage.

General Steps for Fixing a Leaky Faucet

While the specifics vary depending on the faucet type, here are some general steps that apply to most repairs:

1. Turn Off the Water Supply: This is the most critical step! Locate the shut-off valves under the sink (typically for both hot and cold water). Turn them clockwise to completely shut off the water supply to the faucet. If you cannot find the shut off valve under the sink, you must shut off the main water supply to your home.
2. Plug the Drain: Cover your sink drain with a stopper or rag. This prevents any small parts from falling down the drain during the repair process.
3. Release Residual Water Pressure: Turn the faucet handles fully on, both hot and cold to drain the faucet of any remaining water and pressure.
4. Protect the Faucet Finish: Use a towel or rag to protect the faucet’s finish from the wrench.
5. Disassemble the Faucet: Carefully disassemble the faucet, taking pictures as you go to help you remember the order of parts for reassembly.
6. Identify the Problem: Once disassembled, examine the faucet parts to find the source of the leak. Look for worn out o-rings, cracked washers or a buildup of debris.
7. Replace Worn Parts: Install new parts as needed. Be sure to use the appropriate replacement parts for your particular faucet.
8. Reassemble the Faucet: Put everything back together in the reverse order you took it apart, using your pictures as a guide. Ensure you have tightened all the nuts but do not over tighten.
9. Turn the Water Supply Back On: Slowly turn the water supply valves back on under the sink. Check for leaks before fully turning them on and also while the water is running.
10. Test the Faucet: Turn the faucet on and off and check for leaks. If it’s still dripping, you may need to recheck your work or have a more complicated issue.

Fixing Specific Faucet Types

Now, let’s delve into the specifics of fixing each type of faucet:

1. Fixing a Leaky Compression Faucet

Compression faucets are often the easiest to repair. The main culprits behind leaks are usually worn-out washers or O-rings.

Detailed Steps:

1. Shut off the water supply and plug the drain. (See General Steps above)
2. Remove Handle Caps: You’ll likely see a decorative cap covering a screw on the top or side of each handle. Use a small flathead screwdriver to gently pry these caps off.
3. Remove Handle Screws: Use a Phillips head screwdriver to remove the screws that were under the caps.
4. Remove the Handles: Carefully pull off the handles. Sometimes they may be on tight from being there for many years, if so, you may have to gently wiggle them while pulling.
5. Unscrew the Packing Nut: You will now see a nut on top of the stem. Use the adjustable wrench to carefully unscrew the packing nut from the faucet body.
6. Remove the Stem: Once the packing nut is removed, you can pull out the entire stem.
7. Inspect the Washer and O-rings: At the bottom of the stem you should see a rubber washer. Inspect for damage, cracking, or wear. You may also find one or more o-rings around the stem itself, also check these for any signs of damage.
8. Replace Worn Parts: Remove the old washer and o-rings, install new replacement parts, making sure they fit snugly.
9. Inspect Valve Seat: Look into the faucet body, where the stem sits, you will see a circular area. This is the valve seat. This seat could also be damaged, if it’s severely damaged or corroded it should also be replaced, but this will require a special valve seat wrench. If you are unsure about replacing a valve seat, you can consult a professional. Otherwise, inspect it for any damage or debris and clean it up as needed.
10. Reassemble the Faucet: Apply a small amount of plumber’s grease to the threads of the stem. Carefully reinsert the stem, making sure it is properly seated. Tighten the packing nut with the adjustable wrench. Do not overtighten. Reattach the faucet handles and replace the handle screws. Replace the handle caps.
11. Turn the water supply back on and test the faucet.

2. Fixing a Leaky Cartridge Faucet

Cartridge faucets are known for their simple single-handle design. The most common issue is a worn-out cartridge, but also can be o-rings.

Detailed Steps:

1. Shut off the water supply and plug the drain. (See General Steps above)
2. Remove the Handle: Locate the set screw on the side of the handle, sometimes it is hidden by a decorative cap you have to remove with a flathead screwdriver. Use an Allen wrench to loosen and remove the set screw. Then pull off the handle. You may have to wiggle it and gently pull.
3. Remove the Decorative Escutcheon: You’ll likely see a decorative escutcheon (a plate-like piece) covering the base of the faucet. Unscrew or carefully pry it off.
4. Remove the Retaining Clip or Nut: Most cartridge faucets have a retaining clip or nut that holds the cartridge in place. Use pliers or the appropriate wrench to remove this part.
5. Pull Out the Cartridge: Carefully remove the cartridge. Sometimes you can pull it out by hand, other times it will be slightly stuck, you may need to use pliers or the tip of a screwdriver to help pull it out. Note the orientation of the cartridge before removing it, so you know which way to put the new one in.
6. Inspect the Cartridge and O-rings: Check the cartridge for damage or debris. Look at the o-rings for any wear and cracking.
7. Replace the Cartridge and O-rings: Install a new cartridge and any o-rings that may have been removed, use plumber’s grease to lubricate the o-rings.
8. Reassemble the Faucet: Place the retaining clip or nut back into place. Reinstall the decorative escutcheon and reattach the handle and the handle screw.
9. Turn the water supply back on and test the faucet.

3. Fixing a Leaky Ball Faucet

Ball faucets, while also single-handle, have a slightly different internal mechanism. Leaks are commonly due to worn-out O-rings, springs, or the ball itself.

Detailed Steps:

1. Shut off the water supply and plug the drain. (See General Steps above)
2. Remove the Handle: Locate and remove the set screw on the handle using an Allen wrench. Pull the handle off the faucet.
3. Loosen Collar and Remove Spout: There may be a collar nut or decorative ring you need to unscrew. You may have to gently pull up and wiggle the spout as you unscrew the nut. Set the spout aside, being careful to not break any of the parts under the spout.
4. Remove the Ball and O-rings: Carefully lift the ball out of the faucet body. Inspect the o-rings around the base of the faucet body and on the ball for wear and cracking.
5. Remove Springs and Seals: Using a needle nose plier or a small flathead screwdriver, remove the springs and rubber seals beneath the ball and inspect them for damage.
6. Replace Worn Parts: Replace any worn o-rings, springs, seals, and the ball if necessary. Lubricate the o-rings with plumber’s grease.
7. Reassemble the Faucet: Replace the springs and seals under the ball. Place the ball back into the faucet body. Reattach the faucet spout and tighten the collar or decorative ring. Reinstall the handle and tighten the set screw.
8. Turn the water supply back on and test the faucet.

4. Fixing a Leaky Ceramic Disc Faucet

Ceramic disc faucets are often the most durable, but leaks can occur due to damaged seals or a faulty cartridge. Note that most of the parts in a ceramic disc faucet are not replaceable and the entire cartridge must be replaced if there is a leak.

Detailed Steps:

1. Shut off the water supply and plug the drain. (See General Steps above)
2. Remove the Handle: Most ceramic disc faucets have a small screw, sometimes hidden under a decorative cap, on the side of the handle. Use an Allen wrench to loosen and remove the screw. Pull off the handle.
