Getting Ready for the Job
Before you start, gathering the necessary tools and materials is crucial. This will save you time and frustration.
Tools You’ll Need
- Adjustable wrench: For loosening and tightening nuts.
- Basin wrench: A special tool designed for reaching nuts in tight spaces under the sink.
- Phillips head screwdriver: For removing screws.
- Flathead screwdriver: Also for prying off decorative caps.
- Plumbing pliers (or channel-lock pliers): For gripping and turning various parts.
- Bucket or bowl: To catch any residual water.
- Old towels or rags: To absorb spills and protect surfaces.
- Safety glasses: To protect your eyes from debris.
- Work gloves: For a better grip and to protect your hands.
- Flashlight or headlamp: To see clearly in the dark space under the sink.
Materials to Have Handy
- New faucet (if replacing): Ensure you have your replacement ready.
- Teflon tape (pipe thread tape): For sealing new connections.
- Plumber’s putty: For creating a watertight seal around the faucet base.
Step 1: Shut Off the Water Supply
This is the most important first step. You don’t want water spraying everywhere!
- Locate the shut-off valves: Look under the sink. You should see two valves, one for hot water and one for cold water, connected to the water supply lines that go up to the faucet.
- Turn the valves clockwise: Turn them until they are firmly closed.
- Test the water flow: Turn on the faucet handle to release any remaining pressure and confirm that the water is indeed off. Let the water drain completely from the faucet.
Tip: If you can’t find or operate the shut-off valves under the sink, you’ll need to turn off the main water supply to your house. This is usually located in the basement, garage, or near your water meter.
Step 2: Access the Faucet Components Under the Sink
Get down on your hands and knees and peer under the sink. This is where all the action happens.
- Clear the area: Remove any cleaning supplies or items stored under the sink to give yourself plenty of working space.
- Identify the connections: You’ll see the water supply lines connected to the faucet’s tailpieces. You’ll also likely see a mounting bracket or nuts holding the faucet in place.
Step 3: Disconnect the Water Supply Lines
Now it’s time to detach the flexible water supply lines from the shut-off valves.
- Use an adjustable wrench: Place the wrench on the nut connecting the supply line to the shut-off valve.
- Turn counter-clockwise: Loosen and remove the nuts. Be prepared for a small amount of water to drip out. This is why you have your bucket and rags ready.
- Repeat for both lines: Do this for both the hot and cold water supply lines.
Pro Tip: Hold the shut-off valve steady with a second wrench while you loosen the supply line nut. This prevents you from accidentally twisting the valve and potentially damaging the plumbing.
Step 4: Remove the Old Faucet
This is where you’ll likely need your basin wrench.
Removing the Handle and Decorative Cap
Many single-handle faucets have a decorative cap on the handle. This cap often hides the handle screw.
- Pry off the decorative cap: Gently use a flathead screwdriver or a putty knife to pry off the decorative cap. Be careful not to scratch the faucet finish.
- Locate the handle screw: Once the cap is off, you’ll see a screw. This is usually a Phillips head screw.
- Remove the handle screw: Use the appropriate screwdriver to remove the screw.
- Pull off the handle: Once the screw is out, the handle should lift straight off. If it’s stuck, gently wiggle it or use a handle puller (though this is rarely needed for basic faucets).
Detaching the Faucet Body
The faucet body is secured to the sink or countertop from underneath by a mounting nut or a set of nuts and a bracket.
- Locate the mounting nut: Look for a large nut or a series of nuts holding the faucet in place under the sink.
- Use the basin wrench: This is where the basin wrench shines. Its long shaft and pivoting jaw allow you to reach and grip the mounting nut in those awkward spots.
- Turn counter-clockwise: Fit the jaws of the basin wrench onto the mounting nut and turn it counter-clockwise to loosen and remove it. You may need to reposition the wrench several times.
- Remove any washers or brackets: As you loosen the nut, you might also need to remove a metal or plastic washer and a mounting bracket. Keep these aside.
What if the mounting nut is seized? If the mounting nut is corroded or stuck, apply a penetrating lubricant like WD-40 and let it sit for a while. Then, try again with the basin wrench or even plumbing pliers for extra grip.
Lifting Out the Faucet
- Carefully lift the faucet: Once all connections and mounting hardware are removed, you should be able to lift the old faucet straight up and out from the top of the sink.
- Clean the mounting surface: Before installing a new faucet, thoroughly clean the sink or countertop surface where the old faucet was mounted. Remove any old plumber’s putty or sealant.
Step 5: Inspecting the Old Faucet (Optional but Recommended)
If you’re not replacing the faucet but experiencing issues like leaks, you might consider cartridge replacement.
Fathoming the Faucet Cartridge
The cartridge is the heart of a single-handle faucet. It controls the flow and temperature of the water. If your faucet drips or has low water pressure, the cartridge is often the culprit.
- How to access the cartridge: After removing the handle (as described in Step 4), the cartridge is usually visible. It might be held in place by a retaining clip, a nut, or screws.
- Removing the cartridge:
- Retaining Clip: Many cartridges have a metal or plastic clip that needs to be pulled out with pliers.
- Retaining Nut: Some cartridges have a large nut that needs to be unscrewed with a wrench or plumbing pliers.
- Screws: Less common, but some might be held with screws.
- Pulling the cartridge: Once any fasteners are removed, the cartridge should pull straight out. You might need to wiggle it or use pliers gently to get it out. Note its orientation for proper reinstallation.
- Replacing the O-ring: The cartridge will have O-rings on it. These rubber seals can degrade over time and cause leaks. If you’re not replacing the whole cartridge, replacing the O-ring is a good idea. Make sure to get the correct size and type of O-ring. Lubricate new O-rings with plumber’s grease before installation.
What is a faucet cartridge? A faucet cartridge is a self-contained valve that mixes hot and cold water and controls the water flow when you move the handle. They are designed to be a sealed unit, making faucet repair easier.
Step 6: Preparing for the New Faucet (If Replacing)
If you’re installing a new faucet, this is the time to prepare the sink and the new faucet.
- Read the new faucet’s instructions: Every faucet is slightly different. Always refer to the manufacturer’s specific installation guide.
- Apply plumber’s putty or silicone sealant: Most new faucets come with a gasket. However, for added security and a watertight seal, you might want to apply a bead of plumber’s putty or silicone sealant around the base of the faucet where it will meet the sink.
- Feed the supply lines: Thread the new water supply lines (if they are integrated into the faucet) through the holes in the sink or countertop.
Step 7: Installing the New Faucet
This is the reverse of removal.
- Position the new faucet: Carefully place the new faucet onto the sink or countertop, ensuring the supply lines go through the correct holes.
- Secure the faucet from underneath: From under the sink, attach any washers, brackets, and the mounting nut that came with your new faucet. Hand-tighten them first, then use your basin wrench or appropriate tool to snug them up. Don’t overtighten, as this can damage the sink or faucet.
- Connect the water supply lines: Connect the new water supply lines to the shut-off valves. Use Teflon tape on the threads of the shut-off valves for a good seal. Hand-tighten the nuts, then use an adjustable wrench to tighten them another quarter to half a turn.
Step 8: Testing for Leaks
This is a critical step after installation.
- Turn on the shut-off valves slowly: Open the hot and cold water shut-off valves gradually.
- Check all connections: Inspect all the points where the water supply lines connect to the shut-off valves and the faucet. Look and feel for any drips or moisture.
- Turn on the faucet: Slowly turn on the faucet handle. Check the water flow and temperature.
- Run water for a few minutes: Let the water run for a few minutes, continuing to check for leaks under the sink.
- Tighten if necessary: If you find a small drip, try tightening the connection slightly (about an eighth of a turn).
Troubleshooting Common Issues
Sometimes things don’t go perfectly smoothly. Here are a few common problems and how to address them.
Faucet Leaking After Installation
- Check connections: Ensure all mounting nut and water supply lines are tightened properly.
- Inspect O-rings: If the leak is from the spout, the O-ring inside the faucet body might be damaged or improperly seated. This might require disassembling the handle again to check or replace the O-ring or cartridge replacement.
- Plumber’s putty/sealant: Make sure there’s a good seal around the base of the faucet on the sink.
Low Water Pressure
- Aerator: The most common cause of low water pressure is a clogged aerator. The aerator is the small screen at the tip of the faucet spout. Unscrew it (usually by hand) and clean out any debris. You can soak it in vinegar to remove mineral buildup.
- Supply lines: Check that the shut-off valves are fully open. The supply lines themselves could also be kinked.
- Cartridge issue: A faulty or partially blocked cartridge can also restrict water flow.
Faucet Handle is Stiff or Loose
- Handle screw: If loose, tighten the handle screw. If stiff, the cartridge replacement might be needed.
- Cartridge lubrication: Sometimes, the cartridge itself can become dry. If you’ve removed the cartridge for cleaning or cartridge replacement, ensure any O-rings are properly lubricated with plumber’s grease.
Frequently Asked Questions (FAQ)
How long does it take to remove a single-handle kitchen faucet?
It typically takes between 30 minutes to 1 hour to remove a single-handle kitchen faucet, depending on your experience level and whether any parts are corroded or stuck.
Can I replace just the cartridge in a faucet?
Yes, in most cases, you can perform a cartridge replacement to fix leaks or handle issues without replacing the entire faucet. This is a more economical and often simpler solution.
What is an aerator?
An aerator is a small device screwed onto the end of a faucet spout. It mixes air with water, creating a smoother, splash-free stream and also conserving water.
Do I need a basin wrench to remove a faucet?
While it’s possible to use other tools in a pinch, a basin wrench is highly recommended. It’s specifically designed to reach the nuts and bolts in the tight, awkward space behind the sink, making the job significantly easier and safer.
When should I consider a cartridge replacement versus a new faucet?
If your faucet has good exterior condition but suffers from leaks, drips, or stiff handle operation, a cartridge replacement is often the most cost-effective solution. If the faucet is old, damaged, heavily corroded, or you simply want an upgrade in style or functionality, then replacing the entire faucet is the better option.
