Step-by-Step Guide: How to Repair a Leaky Faucet at Home

Step 1: Identify Your Faucet Type

Before you start, it’s helpful to know what type of faucet you have, as the internal components vary. The four main types are:

• Compression Faucets: Two handles (hot and cold) that you twist to turn on/off. They use rubber washers.
• Cartridge Faucets: Often a single lever that moves up/down for flow and side-to-side for temperature. They use a plastic or metal cartridge.
• Ceramic Disc Faucets: Similar to cartridge faucets, often with a single lever, but use two ceramic discs to control water flow.
• Ball Faucets: Commonly found in kitchens, they have a single handle that pivots on a rounded cap. They contain a rotating ball assembly.

Knowing your faucet type will help you get the correct replacement parts.

Step 2: Gather Your Tools and Replacement Parts

Having the right tools on hand makes the job much smoother. You’ll likely need:

• Adjustable wrench
• Screwdrivers (Phillips and flathead)
• Pliers (needle-nose may be helpful)
• Utility knife or small flathead screwdriver (for prying off caps)
• Teflon tape (plumber’s tape)
• Plumber’s grease (silicone-based)
• Clean cloths or towels
• Replacement parts (O-rings, washers, springs, cartridge, or ceramic discs – purchase these after disassembling if unsure, or take the old parts to the hardware store for a match).

Step 3: Shut Off the Water Supply

This is crucial! You don’t want a surprise flood. Look under the sink for two shut-off valves (one for hot, one for cold) and turn them clockwise until tight. If you can’t find them, you may need to turn off the main water supply to your house.

Step 4: Drain the Faucet and Cover the Drain

Turn on the faucet briefly to drain any remaining water from the lines. Then, close the drain stopper or cover the drain opening with a cloth to prevent small screws or parts from falling down and getting lost.

Step 5: Disassemble the Faucet Handle

How you do this depends on your faucet type:

• For most faucets: Look for a decorative cap (often plastic) on the top or front of the handle. Pry it off gently with a utility knife or small flathead screwdriver. Underneath, you’ll find a screw (usually Phillips). Unscrew it and lift the handle off.
• For some single-lever faucets: The screw might be located on the side or back of the handle.

Step 6: Remove the Faucet Body Components

Once the handle is off, you’ll expose the inner workings. The next steps vary slightly by faucet type:

• Compression Faucets: Use an adjustable wrench to carefully unscrew the packing nut (bonnet nut) that holds the stem in place. Pull out the stem assembly. You’ll likely see a rubber washer at the bottom of the stem and another small washer (packing washer) around the stem itself. These are common culprits for leaks.
• Cartridge Faucets: You might see a retaining nut or clip holding the cartridge in place. Remove it (a needle-nose plier can help with clips). Gently pull the old cartridge straight up and out. Note its orientation before removal so you can install the new one correctly.
• Ceramic Disc Faucets: Unscrew the decorative cap and then the mounting screws that hold the disc cylinder in place. Lift out the cylinder. Inside, you’ll find the ceramic discs and rubber seals. Inspect these for wear.
• Ball Faucets: Use pliers to loosen and remove the cap and collar. You’ll then lift out the cam and packing. Beneath these is the ball assembly, often with springs and rubber seats. These are usually sold as a repair kit.

Step 7: Inspect and Replace Worn Parts

This is where you fix the leak!

• Compression Faucets: Remove the old rubber washer from the bottom of the stem (it’s usually held by a screw). Replace it with a new one of the exact same size. Replace the packing washer or wind new Teflon tape around the stem threads before reassembly.
• Cartridge Faucets: Simply insert the new cartridge, ensuring it’s oriented correctly, and secure it with the retaining nut or clip. Replace any O-rings around the spout base if there’s a leak there.
• Ceramic Disc Faucets: Replace the rubber seals and possibly the ceramic discs if they are chipped or worn. Clean the housing thoroughly before installing new parts.
• Ball Faucets: Replace the entire ball assembly, including the springs and rubber seats, using a new repair kit.

If you’re unsure about parts, take the old ones to a hardware store for an exact match. Apply a thin coat of plumber’s grease to new O-rings and moving parts for smooth operation and a better seal.

Step 8: Clean and Reassemble the Faucet

Before putting everything back together, take a moment to clean any mineral deposits or grime from the faucet’s internal components. White vinegar and an old toothbrush work well.

Then, carefully reassemble the faucet by reversing the disassembly steps. Make sure all screws are tightened snugly, but don’t overtighten, as this can damage components.

Step 9: Turn Water Supply Back On and Test for Leaks

Slowly turn the hot and cold water supply valves back on under the sink. Turn on the faucet to check for proper water flow and temperature mixing. Then, carefully inspect around the handle, spout, and any connections for drips. If you see a leak, turn off the water and slightly tighten the problematic connection.

Tips for a Successful Faucet Repair & Common Mistakes

Here are some extra pointers to help you master how to repair a leaky faucet at home:

Helpful Tips:

• Take Photos: Snap pictures with your phone at each step of disassembly. This is incredibly helpful for remembering how to reassemble everything.
• Keep Parts Organized: Lay out removed parts in the order they came off, or put small screws and washers in a cup so they don’t roll away.
• Don’t Force It: If a part isn’t coming off easily, double-check if there’s a hidden screw or clip. Forcing parts can lead to breakage.
• Match Parts Exactly: Always try to get identical replacement parts. Even slight differences can cause new leaks.
• Clean as You Go: Removing mineral build-up inside the faucet can improve its performance and lifespan.

Common Mistakes to Avoid:

• Forgetting to Shut Off Water: The most common and messiest mistake! Always confirm the water is off.
• Losing Small Parts: Small screws, O-rings, and washers can disappear into the drain or onto the floor in a flash. Cover the drain!
• Overtightening: Screwing things too tight can strip threads, crack plastic components, or damage washers, leading to more leaks. Snug is enough.
• Using Wrong Tools: Using pliers on decorative finishes can scratch them. Use the right screwdriver size to avoid stripping screw heads.
• Not Replacing All Worn Parts: Sometimes multiple components contribute to a leak. If you have a repair kit, it’s often best to replace all included parts.
