How to Fix a Leaky Faucet: Step-by-Step Guide to Plumbing Repair

Dealing with a leaky faucet can be frustrating and costly. Not only does it waste water, but it can also lead to higher utility bills.

Quick Tip:
	Make sure you have the correct tools for your faucet. Check the manufacturer’s instructions or consult a professional if you’re not sure.

Step 1: Turn Off the Water Supply

The first step in fixing a leaky faucet is to turn off the water supply. This is important to prevent water from spraying all over the place while you are trying to fix the faucet. Follow the steps below to turn off the water supply:

Locate the shut-off valve under the sink. The valve should be near the pipes that are connected to the faucet.
Turn the valve clockwise until it is tightly closed. This will stop the flow of water to the faucet.
If you cannot find the shut-off valve under the sink, turn off the main water supply to your home. This is usually located outside near the street or in the basement.

Once the water supply is turned off, turn on the faucet to release any remaining water in the pipes. This will also help to relieve any pressure that may have built up in the pipes.

Now that the water supply is turned off, you can move on to the next step in fixing your leaky faucet.

Step 2: Prepare the Sink Area

Before you begin repairing the leaky faucet, it is important to prepare the sink area properly. This will ensure that you have all the necessary tools and materials within arm’s reach and that you do not damage any of the surrounding fixtures or surfaces.

Gather Tools and Materials

Make a list of all the tools and materials you will need for the repair. This may include:

Adjustable wrench
Flathead screwdriver
Phillips screwdriver
Allen wrench
Replacement parts (such as washers, O-rings, and cartridges)
Plumber’s grease
Clean rags or towels

Having all the necessary tools and materials on hand will save you time and prevent frustration during the repair process.

Turn Off Water Supply

Before you start working on the faucet, turn off the water supply to the sink. This can usually be done by turning the shut-off valves under the sink clockwise. If there are no shut-off valves, turn off the main water supply to the house.

Protect the Sink and Surrounding Surfaces

Place a towel or rag in the sink to prevent any small parts from falling down the drain. You may also want to cover the surrounding surfaces with a cloth or cardboard to protect them from scratches or damage.

Remove Handles and Trim

Use a flathead screwdriver to remove the decorative trim from the handles. This will expose the screws that hold the handles in place. Use a Phillips screwdriver or an Allen wrench to remove the screws and take off the handles.

Remove Cartridge or Valve Stem

Depending on the type of faucet, you may need to remove a cartridge or valve stem to access the internal components. Use a wrench or pliers to loosen and remove the cartridge or valve stem.

With the sink area properly prepared, you are now ready to move on to the next step of the repair process.

Step 3: Dismantle the Faucet

Once you have turned off the water supply, it’s time to dismantle the faucet to identify the faulty part and fix it. Here are the steps to follow:

Remove the handle: Depending on the type of faucet, you may need to use a screwdriver or an Allen wrench to remove the handle. Look for a small screw located on the underside of the handle or behind a decorative cap. Unscrew it and gently remove the handle.
Remove the escutcheon plate: The escutcheon plate is the decorative cover that sits against the wall. Use a wrench to remove the mounting nuts that secure it in place.
Remove the cartridge: With the escutcheon plate removed, you can now access the cartridge. Use pliers to gently pull it out of the faucet body. If it’s stuck, wiggle it back and forth while pulling.
Examine the cartridge: Look for any signs of wear or damage, such as cracks or tears in the rubber O-rings. If the cartridge is damaged, it will need to be replaced.
Replace the cartridge: If the cartridge is damaged, take it to a hardware store to find an exact replacement. Install the new cartridge by pushing it into the faucet body and securing it with the retaining clip.
Reassemble the faucet: Put the escutcheon plate back in place and secure it with the mounting nuts. Replace the handle and tighten the screw. Turn the water supply back on and test the faucet to ensure it no longer leaks.

It’s important to note that not all faucets have cartridges. Some may have ceramic disks or ball assemblies that need to be replaced instead. Consult the manufacturer’s instructions or a plumbing professional if you’re unsure.

Now that you’ve successfully dismantled and fixed your leaky faucet, it’s time to put everything back together and enjoy a fully functioning plumbing system once again.

Step 4: Identify the Problem and Replace the Parts

Now that you have turned off the water supply and disassembled the faucet, it’s time to identify the problem and replace the necessary parts. Here’s how:

Identify the Problem

There are several common issues that cause a faucet to leak, including:

Worn out O-rings
Corroded valve seats
Broken or worn out washers
Loose parts
Cracked or damaged pipes

To determine the root cause of the leak, examine the faucet parts carefully. Look for signs of wear and tear, corrosion, or damage. Check the valve seats for pitting or grooves, and examine the washers for cracks or tears. If you can’t identify the problem, consider taking a picture of the parts and consulting a plumbing expert.

Replace the Parts

Once you have identified the problem, it’s time to replace the damaged parts. Here’s how:

Remove the damaged parts carefully using a wrench or pliers.
Take the old parts to a hardware store to find exact replacements.
Install the new parts carefully, making sure they fit snugly and are properly aligned.
Reassemble the faucet and turn on the water supply.
Test the faucet to ensure the leak has been fixed.

If you are unsure about how to replace the parts, consider consulting a plumbing expert. They can provide guidance on the best replacement parts and how to install them properly.

Common Parts to Replace	Approximate Cost
O-rings	$0.50 – $1.00
Valve seats	$2.00 – $4.00
Washers	$0.50 – $1.00
New faucet cartridge	$10.00 – $30.00

Replacing the damaged parts is often a simple and affordable fix for a leaky faucet. By identifying the problem and replacing the necessary parts, you can save money on your water bill and prevent further damage to your plumbing system.

Step 5: Reassemble the Faucet

Once you have replaced all the necessary parts, it’s time to reassemble the faucet. Follow these steps:

Replace the faucet handle: Place the handle back onto the faucet and secure it in place using the screw you removed earlier. Make sure it’s tight enough so that it doesn’t wobble but not too tight that it’s difficult to turn.
Attach the aerator: Screw the aerator back onto the end of the faucet. Make sure it’s tight enough so that water doesn’t leak out around the edges.
Turn on the water supply: Slowly turn on the water supply valves under the sink. Check for any leaks around the base of the faucet and around the handles. If there are no leaks, you’re good to go!

Testing the Faucet

After reassembling the faucet, it’s important to test it to make sure it’s working properly. Here’s how:

Turn on the faucet: Turn on the faucet and check for any leaks around the base or handles.
Check the water pressure: Make sure the water pressure is normal and that water is flowing evenly from both the hot and cold water valves.
Check the temperature: Turn on the hot water and make sure it’s hot. Then turn on the cold water and make sure it’s cold.
Test the aerator: Check the aerator to make sure water is flowing evenly through it. If it’s clogged, you may need to clean or replace it.

Final Thoughts

Reassembling a faucet may seem daunting, but with the right tools and instructions, it’s a DIY project that anyone can tackle. Remember to turn off the water supply before starting and take your time to ensure that you have replaced all the necessary parts correctly. If you encounter any issues or the leak persists, it may be time to call a professional plumber.

Step 6: Test the Faucet

After completing the previous steps of fixing a leaky faucet, it’s time to test the faucet to ensure that the issue has been resolved. Here’s how to do it:

First, turn on the water supply to the faucet by turning the shut-off valves under the sink counterclockwise.
Next, slowly turn on the faucet handle to let the water flow through the spout. Check for any leaks or drips around the base of the faucet and the handles.
If you notice any leaks or drips, turn off the water supply and double-check the connections and parts you replaced or tightened. Make sure everything is properly installed and tightened before turning the water supply back on and testing the faucet again.
If there are no leaks or drips, let the water run for a few minutes to ensure that the water pressure and temperature are correct and that the faucet is functioning properly.
Finally, turn off the faucet and check for any leaks or drips again. If everything looks good, you’re done!

Testing the faucet is an important step in the process of fixing a leaky faucet. It helps ensure that the problem has been completely resolved and that the faucet is working as it should. If you still notice any leaks or drips after testing the faucet, it may be time to call in a professional plumber for further assistance.
