Everything About How To Remove A Delta Kitchen Faucet

Removing an old kitchen faucet is a common task when upgrading your kitchen or fixing a leaky fixture. If you have a Delta kitchen faucet, the process involves shutting off the water, disconnecting the lines, and loosening the mounting hardware under the sink. It might seem tricky, especially working in a tight space, but with the right tools and a clear plan, it is a job many homeowners can handle. This guide walks you through each step, helping you tackle the project with confidence.

Getting Ready for Faucet Removal

Taking time to prepare makes the job much easier and prevents problems. Gathering your supplies and getting the work area ready are the first important steps.

Gathering Your Gear

You will need specific tools to remove old kitchen faucet. Having them all before you start saves you trips looking for things while you are under the sink.

• Adjustable Wrench: Useful for many connections.
• Basin Wrench: This is a special tool with a long handle and a swiveling jaw. It is made for reaching nuts in tight spots, like faucet nuts far up under the sink. A basin wrench kitchen faucet is almost essential for this job.
• Pliers: Channel lock pliers or slip-joint pliers can help with gripping and turning.
• Bucket and Towels: To catch any water that drains out when you disconnect the lines.
• Safety Glasses: Protect your eyes from drips or falling debris.
• Work Light or Headlamp: It is dark under the sink. Good light helps you see what you are doing.
• Old Clothes: You might get wet or dirty.
• Padding or Cardboard: To lie on under the sink.
• Penetrating Oil (Optional but Recommended): For removing stuck faucet nut that are old and corroded.
• Utility Knife or Scraper: To cut away old caulk around the faucet base.
• Wire Brush (Optional): To clean threads if reusing supply lines.

Preparing Your Work Space

The area under the kitchen sink is often full of things. You need clear access to the plumbing and the underside of the faucet.

• Empty the Cabinet: Take everything out of the cabinet under the sink. This gives you room to move and lie down.
• Clear the Area: Remove any trash cans, cleaning supplies, or other items around the sink area that might be in your way.
• Protect the Floor: Put down a drop cloth or old towels on the floor outside the cabinet, just in case of spills.
• Get Comfortable: Put your padding or cardboard down under the sink where you will be working.

Safety First: Finding the Water Shut-Off

This is a critical step. You must turn off the water supply to the faucet before you start disconnecting anything. kitchen faucet shut off valves are usually located on the pipes coming out of the wall or floor right under the sink.

• Locate the Valves: Look for two valves under the sink, one for hot water and one for cold water. They often have round or oval handles.
• Turn Them Off: Turn the handles clockwise until they stop. Do not force them too hard, especially if they are old.
• Check the Water: Turn on the kitchen faucet handles above the sink. A little water might come out at first, but it should quickly stop or slow to a drip if the valves are off correctly. If water keeps flowing strongly, the valves might be old or not working right. You might need to find the main water shut-off for your house (usually in the basement, garage, or outside) or call a plumber.
• Drain the Lines: Once the water is off at the valves, open the faucet handles fully (both hot and cold) over the sink. This lets any water left in the faucet and supply lines drain out. Close the handles after the water stops.

Accessing Undersink Plumbing

Working under the sink requires good access and patience. This is where you will undersink plumbing disconnect the water lines and loosen the faucet from the countertop or sink.

Seeing What You Need To See

Good light is important. Use your work light or headlamp to clearly see the pipes, hoses, and nuts right under the faucet base.

• Identify the Parts: Look up at the underside of the sink where the faucet is mounted. You will see the ends of the hot and cold water supply lines connected to the faucet shanks. You will also see the hardware holding the faucet body to the sink or countertop. This might be one large nut, several smaller nuts on threaded rods, or a plate held by screws. You are looking for the remove faucet mounting nut under sink or kitchen faucet base nut removal components.
• Note the Connections: See how the supply lines connect to the faucet. They are usually threaded connections. For pull-down or pull-out faucets, you will also see a hose connection and possibly a weight on the hose.

Detaching the Water Lines

With the water off and the lines drained, you can now disconnect faucet water supply lines. This is where your adjustable wrench or basin wrench comes in handy.

Working with Flexible Supply Lines

Most modern faucets use flexible braided supply lines. These are easier to work with than rigid pipes.

• Place Your Bucket: Put a small bucket or container under the connections you are about to loosen. Even though you drained the lines, there will likely be some water left that will drip out.
• Identify Connections: The flexible lines connect from your shut-off valves to the threaded shanks hanging down from the faucet body.
• Loosen the Nut: Use your adjustable wrench to grip the nut connecting the flexible line to the faucet shank. Turn the nut counter-clockwise to loosen it. You might need pliers or another wrench to hold the faucet shank steady so it does not turn with the nut.
• Repeat for Both Lines: Disconnect both the hot and cold water supply lines from the faucet shanks. Let the water drain into your bucket.
• Disconnect from Valves (Optional but Recommended): It is often easier to remove the old supply lines with the faucet. You can disconnect the other end of the flexible lines from the shut-off valves using your adjustable wrench. This is part of the undersink plumbing disconnect process.

Working with Rigid Supply Lines

Some older faucets might have rigid copper or plastic supply lines connected directly or with compression fittings.

• Compression Fittings: These have a nut that squeezes a ring (ferrule) onto the pipe to create a seal. To disconnect, loosen the nut with an adjustable wrench. The pipe should then pull out.
• Soldered Copper (Less Common for Faucets): If you see soldered copper pipes going directly to the faucet, this is more complex and might require cutting the pipe. This is less typical for standard faucet connections, which usually have a threaded end or a compression fitting.

Releasing the Faucet from the Sink or Countertop

This is often the most challenging part, especially for older faucets. You need to remove faucet mounting nut under sink that hold the faucet body in place. The type of mounting hardware varies between Delta models, but the general idea is the same: loosen the nut(s) from the threaded part(s) coming down from the faucet body.

Types of Mounting Hardware

Delta faucets can use a few different systems to attach to the sink or counter:

1. Threaded Rods with Nuts: The faucet base has one, two, or three threaded rods extending downwards. Nuts are screwed onto these rods from underneath to hold the faucet tight.
2. Large Mounting Nut: A large plastic or metal nut screws onto a single large threaded shank coming down from the center of the faucet. This is common for Delta single handle faucet removal.
3. Mounting Plate with Screws: A metal or plastic plate fits over threaded shanks, and screws go up into the faucet body to hold the plate and faucet in place. Nuts might still be involved, or the screws themselves secure the assembly.

Using Your Tools for Access

Working directly under the faucet, close to the sink bowl, can be tight. This is where the basin wrench kitchen faucet shines.

• Reaching the Nuts: Standard wrenches are often too bulky or short to reach the mounting nuts, which are usually high up under the sink deck. The long arm and swiveling head of a basin wrench are designed to get into these narrow spaces and grip the nuts from awkward angles.
• How to Use a Basin Wrench:
  • Position the wrench jaw around the nut.
  • Tighten the jaw onto the nut if adjustable.
  • Turn the long handle counter-clockwise to loosen the nut.
  • Be patient; it might be slow going due to the tight space.

Loosening the Mounting Hardware

Focus on freeing the main faucet body from the sink surface. This involves the kitchen faucet base nut removal.

• Identify the Main Nut(s): Look for the large nut or multiple nuts/screws directly under the faucet base. These are distinct from the nuts connecting the supply lines (which you already disconnected).
• Use the Basin Wrench: Position the basin wrench kitchen faucet onto the main mounting nut or nuts. If there are multiple nuts on rods, you will need to loosen each one.
• Turn Counter-Clockwise: Rotate the wrench handle counter-clockwise to loosen the nuts. Keep turning until the nuts are loose enough to remove by hand.
• Remove Washers/Plates: Once the nuts are off, there might be washers, metal plates, or rubber gaskets. Remove these. Pay attention to the order they were in, though it is less critical when removing versus installing.

Dealing with Stuck Nuts

Old faucets often have corroded or rusted nuts that are difficult to loosen. This is the challenge of removing stuck faucet nut.

• Apply Penetrating Oil: Spray a generous amount of penetrating oil (like WD-40 or a dedicated rust breaker) onto the stuck nuts and threaded parts. Let it sit for 15-30 minutes, or even longer if possible. The oil helps to break down rust and corrosion.
• Apply More Leverage: Use the longest wrench or basin wrench you have for better leverage. Sometimes a cheater bar (a pipe slipped over the wrench handle) can provide extra turning power, but be careful not to bend or break something.
• Tap the Nut: Gently tap the nut with a hammer. The vibration can help the penetrating oil work its way in and can sometimes break the corrosion loose.
• Heat (Use Extreme Caution): In rare, very stubborn cases, a small amount of heat from a propane torch might help expand the nut. HOWEVER, this is risky. You are working near plastic pipes, wood cabinets, and potentially flammable materials. This should only be done by someone experienced and with extreme caution, a fire extinguisher ready, and full awareness of surrounding materials. For most DIYers, trying oil, leverage, and patience is safer.
• Cutting the Nut: If all else fails, you might need to cut the nut off. A reciprocating saw with a metal-cutting blade, a hacksaw, or a specialized nut splitter tool can be used. This is a last resort and requires careful work to avoid damaging the sink or countertop.

Specifics for Delta Pull-Down Faucet Removal

If your Delta faucet is a pull-down or pull-out model (part of Delta pull down faucet removal), there is an extra step involved with the spray hose and its weight.

• Locate the Hose Connection: Under the sink, the spray hose that pulls out of the faucet spout is connected to the main water line (usually the hot water line) or a separate connection point under the faucet body. This connection often looks like a quick-connect fitting or a threaded nut.
• Disconnect the Hose:
  • For quick-connect fittings (often plastic): There is usually a collar or clip you need to squeeze or remove to release the hose. Consult your faucet’s manual if you have it, as designs vary.
  • For threaded connections: Use an adjustable wrench or pliers to hold the fitting steady and loosen the nut connecting the spray hose.
• Remove the Weight: Pull-down and pull-out hoses usually have a metal weight attached to the hose line under the sink. This weight helps the hose retract. Find the weight and remove the screws holding it together so you can take it off the hose. You might need a screwdriver.
• Free the Hose: With the hose disconnected and the weight removed, the hose should be free to move. When you lift the faucet body later, you will feed this hose up through the faucet hole.

Lifting Out the Old Faucet

Once all the nuts, bolts, screws, and supply lines are disconnected from underneath, the faucet body should be free from the sink surface.

• From Above: Go back up top to the sink.
• Check for Sealant: The old faucet base is likely sealed to the sink or countertop with plumber’s putty or silicone caulk.
• Cut the Sealant: Use a utility knife or scraper to carefully cut through the old sealant around the edge of the faucet base. Be careful not to scratch the sink surface.
• Lift the Faucet: Gently try to lift the faucet straight up from the sink. If it does not budge, double-check underneath to make sure you did not miss any nuts, screws, or connections (like a sprayer hose or soap dispenser line if they go through the same hole).
• Remove the Faucet: Once it is free, lift the entire faucet body, including any attached supply lines (if you did not disconnect them from the valves), up and out of the sink holes.

Cleaning Up

With the old faucet removed, the area will likely have old caulk, putty, and grime.

• Scrape Away Old Sealant: Use your utility knife or scraper to remove all traces of the old plumber’s putty or silicone caulk from the sink surface and the faucet holes.
• Clean the Area: Use an all-purpose cleaner and scrub away any dirt, soap scum, or mineral deposits around the faucet holes. A clean surface is essential for properly sealing the new faucet.

Troubleshooting Common Removal Issues

Removing an old faucet can present a few challenges. Knowing how to handle them helps.

The Shut-Off Valve Won’t Turn Off

• Problem: The handles are stuck, or water still flows strongly when they are closed.
• Solution: Try gently turning the handles back and forth a few times to free them up. If they still do not work, the internal valve might be broken. You will need to find your home’s main water shut-off valve and turn off the water to the entire house. If you are not comfortable doing this or cannot find it, you may need to call a plumber.

The Mounting Nut is Impossible to Reach

• Problem: The space is too tight for your wrench.
• Solution: Make sure you are using a basin wrench kitchen faucet. This tool is made for this exact situation. If you still cannot get a grip, try different angles. Sometimes coming at it from a slightly different position helps. If the space is truly blocked (e.g., by the sink basin shape or a garbage disposal), you might need to consider if another approach is possible or if professional help is needed.

The Mounting Nut is Stuck Solid

• Problem: The nut is rusted or corroded and will not turn (the removing stuck faucet nut issue).
• Solution: As detailed earlier, use penetrating oil and give it time to work. Apply steady pressure with your wrench. Tapping the nut can help. As a last resort, consider cutting the nut carefully, but be very mindful of your surroundings.

The Faucet Base is Stuck to the Sink

• Problem: You have removed all the nuts underneath, but the faucet will not lift off.
• Solution: The old sealant is holding it. Ensure you have cut through the caulk or putty all the way around the base from the top. Sometimes, you need to give the faucet a gentle twist or tap from the side (with a rubber mallet or block of wood to protect the finish) to break the sealant’s grip.

Dealing with PEX Supply Lines

• Problem: Your supply lines under the sink are made of PEX tubing, possibly connected with crimp rings or expansion fittings instead of standard threaded connections at the valve end.
• Solution: The connection to the faucet will still be a standard threaded nut. However, disconnecting PEX from the shut-off valve might require cutting the PEX pipe below the fitting using a PEX cutting tool. If you need to reuse the valve, you would need to remove the old crimp ring and fitting from the valve using a decrimping tool or similar method, or simply replace the shut-off valve itself. This adds complexity and requires specific PEX tools. Often, it is easier to disconnect the flexible supply line at the faucet end only and leave it attached to the PEX adapter/valve, or plan to replace the shut-off valve entirely.

Frequently Asked Questions

Q: Can I remove a Delta single handle faucet the same way as a two-handle faucet?

A: Yes, the basic steps for Delta single handle faucet removal are the same as for a two-handle faucet. You still need to shut off the water, disconnect the supply lines, and loosen the mounting nuts or hardware under the sink. The main difference is that a single-handle faucet might have a single large mounting nut or multiple smaller nuts on a central body, rather than nuts for separate hot and cold stems like some two-handle faucets. The core process of remove faucet mounting nut under sink remains the same.

Q: Do I really need a basin wrench?

A: While it might be possible with other wrenches in some rare cases, a basin wrench kitchen faucet is highly recommended and often necessary. The space under the sink, especially close to the sink bowl and backsplash, makes it very difficult to use standard wrenches on the mounting nuts which are usually high up on threaded shanks. The basin wrench’s design lets you reach and turn these nuts much more easily and with better leverage. It is a tool worth buying if you plan to do faucet work.

Q: My faucet’s mounting nut is completely rusted. What’s the best way for removing stuck faucet nut?

A: Start by soaking the nut generously with penetrating oil and letting it sit for at least 30 minutes, preferably longer. Tap the nut gently with a hammer to help the oil penetrate. Apply steady pressure with your basin wrench kitchen faucet. If it still won’t budge, reapply oil and wait longer. As a last resort, you may need to cut the nut off carefully using a hacksaw, reciprocating saw, or a nut splitter tool, being very careful not to damage the sink or surrounding plumbing.

Q: What should I do if I disconnect the supply lines and water keeps coming out?

A: This means the kitchen faucet shut off valves are not fully closing or are faulty. Double-check that you turned the handles all the way off (clockwise). If water still flows, you must find and turn off the main water supply valve for your entire house. This valve is often in the basement, garage, near your water meter, or in a utility closet. If you cannot find it or turn it off, you will need to stop the project and call a plumber to address the shut-off valves.

Q: Are there any special steps for Delta pull down faucet removal?

A: Yes, for Delta pull down faucet removal, you have an extra step under the sink. You need to disconnect the pull-down spray hose from the main water connection point (usually where it connects to the hot water line or a mixing chamber). Also, locate and remove the weight that is clamped onto the spray hose line under the sink. You will need to feed the disconnected hose up through the faucet hole when you lift the faucet body out.

Q: I see a lot of pipes and hoses under my sink. How do I know which ones to disconnect?

A: You are focused on the pipes and hoses directly connected to the faucet body itself. These are usually the hot and cold water supply lines coming from the shut-off valves and connecting to the faucet shanks. For pull-down models, there will also be the spray hose. Other pipes like the drain pipe (connecting the sink tailpiece to the trap) or garbage disposal connections are part of the undersink plumbing disconnect but do not need to be disconnected to remove the faucet, unless they physically block access to the faucet mounting hardware. Focus only on the connections going up to the faucet base.

Removing a Delta kitchen faucet is a common plumbing task that requires basic tools, patience, and the steps outlined here. By safely shutting off the water, carefully disconnecting the supply lines, tackling the mounting hardware with the right tools like a basin wrench kitchen faucet, and handling any specific features like a pull-down hose, you can successfully remove your old faucet and get ready for a new one.
