How to Fix a Leaking Faucet Yourself Without a Plumber

A leaking faucet is a common household problem that can be frustrating. Not only does it waste water, but it can also drive up your water bill if not addressed promptly. While it may seem like a task only a plumber can handle, fixing a leaking faucet yourself is a simple process that can save you money and the inconvenience of waiting for a professional. In this guide, we’ll show you how to fix a leaking faucet yourself, step-by-step, using easy-to-follow instructions.

Step 1: Identify the Type of Faucet You Have

Before you start fixing your faucet, it’s essential to know what kind of faucet you’re dealing with. Different faucet types require different approaches to repair. The most common faucet types include:

Compression Faucets: These are the traditional faucets that use a rubber washer to seal the valve. They are usually found in older homes.
Ball Faucets: These faucets are typically found in kitchens and use a ball mechanism to control water flow.
Cartridge Faucets: Common in modern bathrooms, these faucets use a cartridge to control water flow and temperature.
Disc Faucets: These faucets have a ceramic disc inside that regulates the flow of water.

To make the repair process smoother, it’s important to identify the faucet type before proceeding.

Step 2: Gather the Necessary Tools and Materials

To fix your leaking faucet, you’ll need a few tools and materials. Most of these items can be found in your toolbox or purchased from a hardware store. Here’s a list of common items you’ll need:

Adjustable Wrench
Screwdriver (Flathead and Phillips)
Plumber’s Tape (Teflon Tape)
Replacement Washer, O-ring, Cartridge, or Ball
Penetrating Oil (for stubborn parts)
Channel Lock Pliers
Flashlight (optional, but helpful for visibility)
Cloth or Towel (to protect surfaces)

If you’re unsure which parts to buy, take the broken component with you to the hardware store for assistance. If your faucet uses a cartridge or ball, many home improvement stores carry universal replacement parts.

Step 3: Turn Off the Water Supply

Before you start working on the faucet, it’s crucial to turn off the water supply to prevent any accidents or flooding. Here’s how to do it:

Locate the Water Shutoff Valve: The shutoff valve is typically located underneath the sink. There are usually two valves—one for hot water and one for cold water.
Turn the Valves Off: Rotate the valves clockwise to close them. If you cannot locate these valves, you may need to turn off the main water supply to the house.
Open the Faucet: Turn on the faucet to drain any remaining water in the pipes. This will help prevent any water from spilling out when you disassemble the faucet.

Step 4: Disassemble the Faucet

Now that the water supply is turned off, it’s time to disassemble the faucet. The process of taking apart the faucet depends on the type of faucet you have. Here are the general steps for each type:

Compression Faucet:

Remove the Handle: Use a screwdriver to remove the screw that holds the handle in place. You may need to pry off a decorative cap to access the screw.
Unscrew the Valve Stem: Once the handle is removed, use a wrench to loosen and remove the valve stem. The valve stem controls the flow of water, and it’s usually attached to the faucet by a nut.
Inspect the Washer: Once the valve stem is out, you’ll see the rubber washer at the bottom. The washer is often the culprit behind the leak, especially if it’s cracked or worn out.

Ball Faucet:

Remove the Handle: To begin, remove the handle by loosening the screws with a screwdriver.
Take Out the Cap and Collar: After the handle is removed, use your hands or pliers to remove the decorative cap and collar from the faucet.
Remove the Ball Assembly: You will need a special tool called a ball faucet tool to remove the ball assembly. This part controls the flow of water and may be the source of the leak.
Inspect for Wear: Check the ball assembly for any signs of damage, and look at the seals or O-rings for wear.

Cartridge Faucet:

Remove the Handle: As with other types of faucets, start by removing the handle with a screwdriver.
Take Out the Cartridge: Once the handle is removed, use pliers or a wrench to pull out the cartridge. The cartridge controls the flow and temperature of water, and it’s often the cause of leaks.
Inspect the Cartridge: Look for any visible signs of wear or corrosion on the cartridge. If the cartridge is damaged, it will need to be replaced.

Disc Faucet:

Remove the Handle: Use a screwdriver to remove the screw that holds the handle in place.
Take Out the Escutcheon: This is the cover plate that hides the inner components of the faucet. Remove it to expose the disc cartridge.
Remove the Cartridge: The ceramic disc cartridge is usually the cause of a leaking disc faucet. Carefully remove it and inspect for wear.
Inspect the Seals: If the seals or the ceramic disc are damaged, you will need to replace them.

Step 5: Inspect and Replace the Damaged Part

Once the faucet is disassembled, it’s time to inspect the parts. Leaking faucets often occur due to damaged washers, O-rings, or cartridges. Here’s how to identify and replace each part:

Washers: A worn or damaged washer is the most common cause of a leak in a compression faucet. Examine the washer closely to see if it’s cracked or flattened. If it’s damaged, replace it with a new one of the same size.
O-Rings: If your faucet is a ball or cartridge type, worn-out O-rings can lead to leaks. These rubber rings help seal the faucet components, and if they are cracked or dried out, they won’t provide a proper seal. Replace the O-ring with a new one.
Cartridges: In cartridge faucets, the cartridge is often the source of the leak. If it’s cracked or clogged with mineral deposits, it needs to be replaced. You can buy a replacement cartridge from your local hardware store.
Ball Mechanism: In ball faucets, the ball can become worn or damaged over time. If the ball is faulty, replace it with a new one to prevent leaks.

Once you’ve replaced the damaged parts, reassemble the faucet by reversing the disassembly steps. Be sure to use plumber’s tape on threaded connections to ensure a tight seal.

Step 6: Reassemble the Faucet

After replacing the faulty part, it’s time to put everything back together. Follow these steps:

Reinstall the Cartridge or Ball: Place the new cartridge or ball assembly back into the faucet.
Tighten the Screws: Use your wrench to tighten any nuts or screws that hold the faucet components in place.
Replace the Handle: Attach the handle back to the faucet and secure it with the screw.
Reattach the Escutcheon or Collar: For ball and disc faucets, reattach the decorative cover or collar.
Turn on the Water Supply: Once the faucet is fully reassembled, turn on the water supply by opening the shutoff valve. Then, turn on the faucet to check for leaks.

Step 7: Test the Faucet

After reassembling the faucet and turning the water supply back on, test the faucet to ensure the leak is fixed. Run both hot and cold water through the faucet, and check for any signs of leaks. If there’s still a leak, double-check the parts you replaced and ensure everything is tightened properly. If the faucet continues to leak despite the repairs, there may be an underlying issue that requires professional attention.

Common Faucet Problems and Solutions

While fixing a leaking faucet is a straightforward process, there are other issues that can arise. Here are some common faucet problems and how to fix them:

Dripping Faucet After Turning It Off: This is a common problem, especially with compression faucets. It’s usually caused by a worn-out washer. Replace the washer to solve the problem.
Low Water Pressure: If you notice low water pressure from the faucet, it could be due to a clogged aerator. Unscrew the aerator from the faucet and clean it to restore normal water flow.
Faucet Handle Is Stiff: A stiff handle can occur if the faucet parts are clogged with mineral deposits. Clean the faucet components to remove any buildup, and lubricate the moving parts.

Fixing a leaking faucet yourself is a simple task that can save you money and prevent water wastage. By following the steps outlined in this guide, you can address leaks in various types of faucets, including compression, ball, cartridge, and disc faucets. With a few basic tools and replacement parts, you can restore your faucet to working order and stop the annoying drip once and for all. Remember, if you encounter any difficulties or the leak persists after replacing the parts, it’s always a good idea to seek professional help. However, with a little patience and the right tools, most leaks can be fixed quickly and easily without the need for a plumber.
