You can take out a kitchen faucet by first turning off the water supply using the plumbing shut-off valves, then disconnecting the supply lines, removing the fasteners holding the faucet in place from under the sink, and finally lifting the old unit out. This guide will walk you through every simple step needed for removing old faucet parts successfully.
Preparing for Faucet Removal
Taking out an old kitchen faucet might seem like a tough job. But, with the right steps, it’s quite easy. Good planning makes the job much faster. This process is the first big step when you are replacing kitchen faucet fixtures.
Gathering Your Essential Tools
You need the right tools before you start working under the sink. Having everything ready saves time later. It makes working in that tight space much easier.
Here is a list of helpful items:
- Basin wrench (a must-have for hard-to-reach nuts)
- Adjustable wrench or pliers
- Bucket and old towels
- Safety glasses
- Flashlight or headlamp
- Scraper or putty knife
- Penetrating oil (for stuck nuts)
- Safety gloves
If you are working on a specific type of faucet, like a single handle faucet removal, some tools might be more important than others. A basin wrench is key for almost any faucet removal.
Locating and Shutting Off the Water Supply
This is the most important safety step. You must stop the water flow before you disconnect water lines faucet. Look under the sink cabinet. You should see two valves connected to the hot and cold water lines leading up to the faucet.
- Turn the hot water valve clockwise until it stops.
- Turn the cold water valve clockwise until it stops.
If you cannot find these valves, or if they do not work, you must turn off the main water supply to your house. Turn off the main valve completely. Test the old faucet by turning on both the hot and cold handles above the sink. If only a small drip comes out, you have successfully shut off the water. This confirms you are ready to move on.
Clearing the Workspace
The space under the sink is usually full of cleaning supplies. Move everything out. You need clear space to lie down or kneel comfortably. Lay down old towels or a tarp. Water might drip when you disconnect water lines faucet. The bucket should be ready to catch any drips. Good lighting is crucial for seeing the parts you need to work on, so grab your flashlight now.
Disconnecting the Water Supply Lines
Now that the water is off, we focus on the lines connecting the faucet base to the shut-off valves.
Separating Supply Lines from Valves
Use an adjustable wrench for this step. Be gentle but firm.
- Place the wrench on the nut where the flexible supply line meets the shut-off valve.
- Turn the nut counter-clockwise to loosen it.
- Hold the valve steady with your other hand so you do not twist the pipe leading into the wall or floor.
- Once loose, unscrew the nut by hand. Expect a little water to spill out. Let it drip into your bucket.
Detaching Supply Lines from the Faucet Body
The other end of the supply lines connects directly to the base of the faucet. Sometimes these lines are permanently attached to the faucet body. If they are removable, repeat the process from above. If the lines are fixed to the faucet, you will remove the whole assembly later, lines and all. If you have access, disconnecting here makes removing old faucet easier, especially if the lines are old or corroded.
Locating and Loosening the Faucet Mounting Hardware
This is often the trickiest part of the entire job. The fasteners are usually tight and hard to reach. This is where under sink tools for faucet become essential.
Identifying the Mounting Hardware
Look up from under the sink, directly beneath where the faucet body sits. You will see nuts, screws, or mounting brackets holding the faucet tight against the sink deck or countertop. Modern faucets often use a single large nut or bracket system. Older faucets might have two smaller mounting nuts.
If you are working with a single handle faucet removal, you will usually find one large locking nut or a bracket held by two bolts.
Dealing with Corrosion and Tight Nuts
If the nuts look old or rusty, they might be seized tight. Do not force them too hard immediately.
- Spray penetrating oil directly onto the threads of the nuts.
- Wait about 15 to 20 minutes for the oil to soak in and break down any rust or mineral buildup.
Using the Right Tool: The Basin Wrench
A standard wrench often cannot reach the faucet mounting nut because of the basin or cabinet walls in the way. A basin wrench is specifically designed for this job. It has a long handle and a swiveling jaw that grabs nuts in tight spots.
- Adjust the jaw of the basin wrench to fit the nut snugly.
- Position the wrench onto the nut. For most removal jobs, you turn the nut counter-clockwise to loosen it.
- Apply steady, upward pressure. This motion pulls the wrench handle toward you while turning the nut away from you.
If the basin wrench fails because the nut is too corroded, you may need to switch tactics.
Alternative Removal Methods for Stubborn Nuts
If the nut simply won’t budge, you have a few options before calling a professional plumber for your kitchen faucet replacement guide.
- The Coping Saw Method: If you can access the threads above the nut, you can try cutting the nut off. Use a small coping saw or a hacksaw blade wrapped in tape for a handle. Carefully saw through the side of the nut until it splits. Once split, it should come off easily. Be very careful not to saw into the sink material or the faucet shank.
- The Oscillating Multi-Tool: If you have one, this tool can be very effective at cutting through metal mounting hardware without damaging surrounding surfaces too much.
Dealing with Drain Pipe Interference
Sometimes, the drain pipe interference blocks easy access to the mounting nuts. This is common if the disposal unit or P-trap is situated directly underneath the faucet mounting area.
- If possible, temporarily loosen the slip nuts on the P-trap and move the drain pipe aside slightly.
- If you have a garbage disposal, it usually needs to be unclipped from its mounting ring under the sink to gain necessary clearance. Place a small bucket underneath before loosening disposal clamps, as water often remains trapped inside.
Once all the fasteners are removed, the faucet should be loose on top of the sink.
Lifting the Old Faucet Out
With all connections severed and mounting hardware gone, you can now remove the old fixture.
Separating the Faucet from the Sink Deck
Gently wiggle the faucet body. Sometimes, old caulking or plumber’s putty seals the base of the faucet to the sink surface.
- If it feels stuck, go above the sink. Use a putty knife or scraper to gently work around the edge of the faucet base.
- Slide the knife between the faucet base and the sink deck. Work slowly around the entire perimeter. This breaks the seal.
- Return under the sink. Try lifting the faucet again. It should now come free easily. If you have a separate sprayer or soap dispenser, these will lift out too.
Cleaning the Surface
Once the old unit is out, you will see an outline of dirt, grime, and old sealant where the faucet sat. This area must be spotless before installing new sink faucet.
- Use a plastic scraper to remove the bulk of the old putty or caulk.
- Wipe the area down with a cloth dampened with mineral spirits or a mild cleaner to remove any residue.
- Ensure the surface is completely dry before proceeding with the new faucet installation.
Considerations for Different Faucet Types
The general procedure remains the same, but some faucets require specific attention during removal.
Single Handle Faucet Removal Specifics
Single handle faucet removal often involves a single shank or cartridge housing secured by one large nut or a retaining plate. The challenge here is that the cartridge or handle mechanism itself might be bulky and prevent you from easily reaching the securing nut with a standard wrench. A good basin wrench is your best friend here. Sometimes, the locking mechanism is hidden under a decorative cap or behind the handle lever itself. Check the manufacturer’s instructions if you have them, as some require removing the handle screw first to access the internal components before getting to the main mounting hardware.
Three-Hole Faucet Removal
If your old faucet uses three separate holes (hot handle, cold handle, and spout), you will have separate supply lines and potentially separate mounting hardware for each piece. Ensure you disconnect water lines faucet for both handles as well as the main spout. Removal might be slightly more time-consuming as you deal with three separate bases instead of one.
What If You Can’t Find the Shut-Off Valves?
If you cannot locate the plumbing shut-off valves under the sink, do not proceed with disconnecting the lines. Trying to remove the faucet without turning off the water will result in a flood.
Your next steps should be:
- Check Nearby Fixtures: Look under the nearest accessible sink or toilet. Sometimes, the shut-off for the entire kitchen is shared or located near another wet area.
- Locate the Main Shut-Off: Every home has a main water shut-off valve, usually located where the water line enters the house (basement, utility closet, or outside near the water meter). Turning this off stops all water flow to the entire house.
Once the main water is off, open the faucet handles above the sink to drain any remaining water pressure in the lines.
Planning Your Kitchen Faucet Replacement Guide
Once the old faucet is successfully out, take a moment to compare the old fixture with the new one you plan to install. This is part of a solid kitchen faucet replacement guide.
| Component Check | Old Faucet Status | New Faucet Status | Action Required |
|---|---|---|---|
| Number of Holes | 1, 2, 3, or 4 | Must match | If mismatch, consider deck plate or drilling new holes. |
| Supply Line Length | Measure the distance | Check new lines | May need to purchase longer or shorter lines. |
| Mounting Style | Nut or Plate | Check mounting hardware | Ensure you have the correct under sink tools for faucet ready for the new hardware. |
| Soap Dispenser/Sprayer | Present or Missing | Check deck holes | Decide if you will use or cap off extra holes. |
Knowing what you are dealing with prevents surprises when you move to installing new sink faucet.
Post-Removal Inspection and Cleanup
Before installing the new faucet, inspect the area thoroughly. This proactive step prevents future leaks and problems.
Inspecting the Faucet Shank Openings
Look at the holes in the sink deck or countertop. Ensure no debris is stuck inside the hole where the faucet shank passes through. Any remaining grit can prevent the new faucet from sitting perfectly flush, leading to leaks under the base.
Checking Supply Line Connections in the Wall
Briefly inspect the threads where the shut-off valves connect to the house plumbing. If they look rusty, brittle, or show signs of long-term leakage, consider replacing the shut-off valves while the area is empty. This proactive maintenance is far easier now than later. If you replace a valve, remember to turn the water off at the main first!
Fathoming Sealant Needs
Determine what the new faucet requires for sealing. Most modern faucets come with a gasket designed to sit between the faucet base and the sink. If the manufacturer recommends or you prefer extra protection, a thin bead of silicone caulk can be applied around the base plate before setting the faucet down. Plumber’s putty is an alternative, especially good for sealing drains, but silicone often lasts longer on faucet bases.
By following these detailed steps, you have successfully navigated the complex process of taking out an old fixture, ensuring your path is clear for installing new sink faucet smoothly.
Frequently Asked Questions (FAQ)
How long does it usually take to take out an old kitchen faucet?
For an experienced DIYer, removing an old faucet can take 30 minutes to an hour, especially if the mounting nuts are accessible. For a beginner, or if the faucet is very old and corroded, expect it to take 1 to 2 hours, mostly due to fighting stuck nuts or dealing with tight spaces and drain pipe interference.
What is the main tool needed for removing a faucet from under the sink?
The most crucial tool is a basin wrench. It lets you reach and turn the faucet mounting nut located high up behind the sink basin where your hand or standard wrenches cannot fit.
Do I need to turn off the main water supply if I can find the local shut-off valves?
No, if you successfully locate and operate the plumbing shut-off valves for the hot and cold water lines leading directly to the faucet, turning off the main supply is unnecessary. Always test the faucet handles afterward to confirm the water is truly off before attempting to disconnect water lines faucet.
My faucet has only one handle. Does single handle faucet removal require different tools?
The process is very similar. A single handle faucet usually attaches with one large locking nut or mounting bracket assembly. You will still rely heavily on the basin wrench to access this main securing hardware from below.
Is plumber’s putty always necessary when installing new sink faucet?
Many modern faucets come with rubber or foam gaskets designed to seal the faucet base to the sink deck. If your new faucet includes a gasket, putty may not be necessary. However, some people still use a very thin bead of silicone caulk or plumber’s putty as extra insurance against water seeping under the base plate. Always check the new faucet’s instructions first.
