Getting Ready for Faucet Removal
Taking out an old faucet needs some planning. Gather your tools first. This saves trips back and forth. You will work in a tight spot. The space under your sink is often small and dark. Clearing this space helps a lot. Take everything out from under the sink. This gives you room to move. Put down an old towel or bucket. It can catch any water drips. Turning off the water is the first big step.
Tools You Will Need
Having the right tools makes the job easier. Some tools are a must-have for this task. Others are helpful if things are stuck.
- Adjustable wrench or basin wrench. A basin wrench is best for tight spaces.
- Pliers.
- Bucket or old towels.
- Safety glasses.
- Flashlight or headlamp.
- Utility knife or small saw (maybe needed for old pipes).
- Penetrating oil (like WD-40) for corroded faucet parts.
- Gloves.
Use the adjustable wrench or basin wrench. The basin wrench is long and thin. It reaches nuts tucked up high under the sink. Pliers can help hold pipes or nuts still. The bucket catches drips. Safety glasses protect your eyes. A good light lets you see what you are doing in the dark space.
Shutting Off the Water
This step is very important. You must stop water flow before you start. Look under the sink cabinet. You will see the hot and cold water lines. These pipes connect the faucet to the water supply in your house. Each line usually has a shut-off valve. They look like small handles or knobs.
Turn these valves all the way off. Turn the handle clockwise. Turn it until it stops. Do this for both the hot and cold water lines. If these valves do not work, or if your sink does not have them, you must turn off the main water supply to your house. This is usually in your basement, garage, or outside.
After you turn off the valves under the sink, open the faucet handles on the sink. Let any water left in the pipes drain out. This lowers the pressure. It helps avoid a big mess. Close the faucet handles after the water stops.
Checking the Water is Off
To be sure the water is off, turn the faucet handles on the sink again. No water should come out. If water still runs, the shut-off valves are not working. Or maybe you did not turn them off completely. Double-check the valves under the sink. If they are fully off and water still runs, you will need to turn off the main water supply to your house.
Working Underside of Sink
Now the real work begins under the sink. The space is tight. Be patient. You are looking for the parts that hold the faucet in place. These are under the sink deck or countertop. Find where the faucet base sits on the sink. Look directly under that spot.
You will see the ends of the supply lines coming down from the faucet. They connect to the shut-off valves you just turned off. You will also see the faucet shank. This is a threaded pipe part of the faucet that goes through the sink hole. The U-shaped bracket holds this shank tight against the sink.
Identifying the U-Shaped Bracket
Look up under the sink base, right where the faucet goes through. You should see a metal piece. It will likely be U-shaped or sometimes shaped like a horseshoe or half-moon. This is the mounting nut or retaining nut system for your faucet.
The U-shaped bracket fits around the faucet shank. It is held in place by one or two nuts that thread onto the shank. Often, there is also a crescent washer. This washer is usually metal or plastic. It also has a U or C shape. It sits between the U-shaped bracket and the nut. This design allows the bracket and washer to fit around the supply lines that also come through the sink hole.
Disconnect Water Lines
Before you can remove the bracket, you need to free the supply lines. These are the flexible hoses that connect the faucet to the hot and cold water lines coming from the wall or floor. There is one hose for hot and one for cold water.
Use your adjustable wrench or pliers to loosen the nuts connecting the supply lines to the shut-off valves. Hold the valve steady with one hand or another wrench so you do not damage it. Turn the nut counter-clockwise.
Be ready for a little water to drip out. Even after draining the faucet, some water stays in the lines. Have your bucket or towel ready under the connections. Loosen both the hot and cold nuts. Once loose, you should be able to unscrew them by hand. Let the ends of the supply lines hang into the bucket to catch drips.
Sometimes the supply lines are connected directly to the faucet shank with nuts up near the U-shaped bracket. More often, the flexible lines attach to threaded pipes coming from the faucet base. If your lines connect up high, you will disconnect them there. Use your basin wrench if space is tight.
Dealing with Stuck Connections
Water connections can get stuck over time. Minerals in the water cause build-up. This makes nuts hard to turn. If a nut is stuck, try spraying it with penetrating oil. Let it sit for a few minutes. Then try again with your wrench. Be firm but do not force it too hard at first. You do not want to bend or break pipes.
If a nut is very stubborn, you might need to use more force. But be careful not to damage the shut-off valve or the pipes in the wall. In very bad cases, you might need to cut the old supply lines. Use a utility knife or a small pipe cutter. If you cut them, you will need new supply lines when replacing kitchen faucet.
Removing the Mounting Nut and Bracket
This is the core step for this type of faucet. The U-shaped bracket is held by a large nut or sometimes two smaller nuts threaded onto the faucet shank. The shank is the main threaded pipe coming down from the faucet base.
Locate the large nut (the retaining nut) that holds the U-shaped bracket and crescent washer against the underside of sink. This nut is often plastic or brass. It can be tricky to reach. This is where a basin wrench shines. The head of a basin wrench pivots. It can grab nuts in awkward spots where a standard wrench cannot fit.
Put the basin wrench onto the nut. Turn the nut counter-clockwise. This might take some effort. Especially if the faucet has been there for a long time. Corrosion is common in wet areas. If the nut is stuck due to a corroded faucet, spray it with penetrating oil. Let the oil soak in. Try loosening it again.
Tips for Stuck Nuts
- Penetrating oil: This is your friend for rust or corrosion. Spray it on the nut and threads. Give it time to work (5-10 minutes or more).
- Heat (use with extreme caution): A little heat can help expand the nut slightly. Only do this on metal nuts/parts. Use a heat gun or even a hairdryer (less risky). Never use a torch near pipes, wood, or anything flammable! This is often not needed for a kitchen faucet nut and can be risky. Use as a last resort and be very careful.
- Tap the wrench: Sometimes a few sharp taps on the wrench handle with a hammer can help break the nut free.
- Two wrenches: If possible, use one wrench to hold the shank steady while you turn the nut with another. This prevents the whole faucet from turning above the sink.
Once the nut starts to turn, keep loosening it. It will thread down the shank. As you loosen the nut, the pressure on the U-shaped bracket will release.
Taking Off the Bracket and Washer
After the mounting nut is loose and moved down the shank threads, the U-shaped bracket is free. It will be sitting loosely around the faucet shank and supply lines. Take the nut off the shank completely. Then, you can usually slide the U-shaped bracket down and off the shank.
Right above the U-shaped bracket, you will likely find the crescent washer. This washer might stick to the underside of sink a little. Or it might come off with the bracket. Remove the crescent washer as well. Keep these parts together if you think you might need to see how they fit later. But for replacing kitchen faucet, you will use the new faucet’s hardware.
Now, the only things going through the sink hole should be the faucet shank and the ends of the supply lines (if they disconnect up high) or the flexible supply hoses themselves. The faucet is no longer held tightly to the sink deck.
Removing the Old Faucet
With the bracket and washer removed, the faucet above the sink is now loose. Go back above the sink. You should be able to lift the old faucet straight up and out of the sink hole.
Lift it carefully. The supply lines are still attached to the faucet body. You will pull these up through the hole with the faucet. If the lines are long, they might get tangled or catch under the sink. Take your time pulling them through.
If the faucet seems stuck from the top, it might be sealed to the sink with old caulk or plumber’s putty. Use a utility knife or scraper to carefully cut around the base of the faucet where it meets the sink. Do not scratch the sink surface. Once the seal is broken, the faucet should lift free.
Place the old faucet aside. You have successfully removed the main part of the corroded faucet.
Clearing the Sink Area
With the old faucet out, the hole in the sink is empty. This is a good time to clean the area. Scrape off any old caulk or putty from the sink surface around the hole. Use a plastic scraper to avoid scratches. Clean away any dirt or grime. A clean surface helps when you install the new faucet.
Inspect the sink hole and the underside of sink. Look for any damage. This area is now ready for the new faucet.
Preparing for Replacing Kitchen Faucet
You have removed the old faucet. The next step is putting in the new one. The process for installing a new faucet is generally the reverse of taking the old one out. However, every faucet is different. Always read the instructions that come with your new faucet.
Your new faucet will come with its own mounting hardware. This might include a U-shaped bracket system, or it could use a different design, like nuts that tighten from above or below without a bracket.
Make sure your new faucet fits the number of holes in your sink. Some sinks have one hole, some have three, and some have four (for a sprayer or soap dispenser). If your new faucet needs fewer holes than your sink has, you can buy a deck plate or base plate. This piece covers the extra holes.
You might need new supply lines. The old ones might be worn, or they might not fit the connections on your new faucet. It is often a good idea to replace supply lines anyway. They are not expensive and new ones give you peace of mind against leaks. Buy supply lines that are the correct length and have the right connectors for your new faucet and your shut-off valves.
Dealing with Challenges: The Corroded Faucet
Older faucets, especially those that have been in place for many years, can be hard to remove. Metal parts can rust or corrode. Nuts can fuse to threads. Plastic parts can become brittle and break.
If you face a severely corroded faucet, be patient.
* Penetrating Oil: Reapply penetrating oil multiple times if needed. Let it soak in for longer periods.
* Gentle Force: Apply firm, steady pressure with your wrench. Avoid sudden, strong jerks that could break things.
* Cutting: In extreme cases, you might need to cut the faucet shank or the mounting nut. This is a last resort. Use a hacksaw or a small reciprocating saw with a metal blade. This requires careful work in the tight space under the sink. Be very careful not to cut yourself, the sink, or the pipes in the wall. If you are not comfortable doing this, it might be time to call a plumber.
When to Call a Pro
Most faucet removal jobs are DIY friendly. But there are times when calling a plumber is wise:
* You cannot turn off the water. If shut-off valves or the main valve are broken or missing.
* The corroded faucet parts will not budge even with oil and tools. You risk breaking pipes.
* You encounter unexpected plumbing issues under the sink.
* You are not comfortable working in tight spaces or using tools like saws near water pipes.
* You damage a pipe or valve during the removal.
A plumber has tools and experience to handle tough situations quickly and safely.
Detailed Steps for Removing the Bracket System
Let’s break down the specific steps for the U-shaped bracket system clearly.
Step 1: Turn Off Water
* Find the hot and cold water lines under the sink.
* Turn the shut-off valves for both lines clockwise until they stop.
* Open the faucet handles above the sink to drain water and release pressure.
* Close the faucet handles.
Step 2: Clear the Area
* Remove everything from under the sink cabinet.
* Place a bucket or towels under the faucet area to catch drips.
Step 3: Disconnect Supply Lines
* Locate where the flexible supply lines connect to the shut-off valves.
* Use an adjustable wrench or pliers to loosen the nuts. Turn counter-clockwise.
* Hold the valve steady while turning the nut.
* Finish unscrewing the nuts by hand.
* Let the line ends drip into the bucket.
* If supply lines connect higher up near the faucet base, disconnect them there using a basin wrench if needed.
Step 4: Find the Bracket and Nut
* Look directly up under the sink where the faucet comes through.
* Identify the U-shaped bracket. It will surround the faucet shank and likely the supply lines.
* Find the large mounting nut or retaining nut below the bracket, threaded onto the shank. You may also see a crescent washer between the nut and the bracket.
Step 5: Loosen the Nut
* Use a basin wrench or large adjustable wrench to grip the nut.
* Turn the nut counter-clockwise to loosen it.
* If the nut is stuck (corroded faucet), apply penetrating oil and wait.
* Be patient and apply steady pressure.
Step 6: Remove Nut, Washer, and Bracket
* Continue unscrewing the nut down the shank.
* Remove the nut completely from the threads.
* Slide the U-shaped bracket down the shank and off.
* Remove the crescent washer (it might come off with the bracket or be separate).
Step 7: Lift the Faucet
* Go back above the sink.
* The faucet should now be loose.
* Lift the faucet straight up out of the sink hole.
* Guide the attached supply lines up through the hole.
* If sealed with caulk, cut the seal first.
Step 8: Clean the Area
* Scrape old caulk or putty from the sink surface around the hole.
* Clean the sink deck and the underside of sink area.
You have now finished removing the old faucet. You are ready for replacing kitchen faucet.

Focusing on Readability
Taking apart things like faucets can sound complex. But breaking it down makes it simple. We use easy words. Short sentences help too. This makes the steps clear.
Instead of saying “Initiate the cessation of the aqueous flow,” we say “Turn off the water.”
Instead of saying “Ascertain the location of the fastening components,” we say “Find the nuts and bracket.”
Using words like “find,” “use,” “turn,” and “lift” makes the action clear. This guide is meant for anyone to follow, not just experts.
The underside of sink area is often the hardest part. It is dark. It is cramped. Feeling around helps. Use your light. A good flashlight makes a big difference. Knowing what parts you are looking for makes finding them easier. The U-shaped bracket looks like a ‘U’. The nut is round and threads onto the pipe. The crescent washer looks like a ‘C’ or half-moon.
Remember the supply lines. They are flexible hoses. They connect to the shut-off valves. They run up to the faucet body. You must disconnect them first. This frees up space. It also stops water from flowing when you take the faucet out.
If you have an old, corroded faucet, expect a challenge. Rust and mineral build-up make metal parts hard to move. Penetrating oil is your best friend here. Spray it. Wait. Try again. It might take a few tries. Do not get frustrated. Steady effort works better than sudden force.
Replacing kitchen faucet is a good home project. It saves money compared to hiring a plumber just for removal and install. Once the old one is off, putting the new one on is usually easier. New parts fit better. New nuts turn smoothly.
Keep the old faucet parts until the new faucet is fully installed and working. This way, you can check how things fit together if you forget. Though, the new faucet’s instructions are the best guide for its specific parts.
The U-shaped bracket is just one way faucets are held on. Some use large plastic nuts with wings you can turn by hand. Some use a different type of metal plate and bolts. But the basic steps are often similar: turn off water, disconnect lines, loosen hardware under the sink, lift faucet.
Knowing about the U-shaped bracket specifically helps because you know what to look for under your sink. It tells you that you will need a wrench, likely a basin wrench, to get to the nut holding it on. And it tells you there is probably a matching crescent washer there too.
The goal is to get the old faucet out without damaging your sink or your water pipes. Taking your time is key. Do not rush. Read each step. Look carefully under the sink. If something doesn’t look right, stop and check online or a plumbing book.
Think about the hot and cold water lines. They are color-coded sometimes. Red for hot, blue for cold. This helps keep them straight. When disconnecting, remember which is which. The new faucet will have marked connections too.
If you are replacing kitchen faucet because the old one leaks or is ugly, this removal process is the first step to a better kitchen. A new faucet can update the look of your sink. It can also save water if it is a newer, more efficient model.
So, to remove your kitchen faucet with a U-shaped bracket: turn off water at the hot and cold water lines, clear space under the sink, disconnect water lines, find the U-shaped bracket and mounting nut/retaining nut with a crescent washer on the underside of sink, loosen the nut with a basin wrench (use oil for corroded faucet), remove the nut, washer, and bracket, then lift the faucet out from the top, ready for replacing kitchen faucet.
This process is manageable. You can do it. Just follow the steps and be prepared for parts that might be stuck. Good luck!
Frequently Asked Questions (FAQ)
Q: What if I don’t have a basin wrench? Can I use a different tool?
A: A basin wrench is best for the tight spot under the sink. It reaches high up and around pipes. You might be able to use a deep socket wrench or a specific faucet wrench if the nut is easy to reach. But a basin wrench is made for this job. It makes it much easier. If you plan to do plumbing work again, buying one is a good idea.
Q: How do I know if my faucet has a U-shaped bracket?
A: You need to look under the sink. Feel and look directly under where the faucet sits on the counter or sink. If you see a metal piece shaped like a ‘U’, ‘C’, or horseshoe that wraps around the faucet shank and is held by a nut, then you have this type of mounting system.
Q: My mounting nut is plastic. Are those easier to remove?
A: Plastic nuts can be easier if they are not overtightened or old and brittle. They don’t rust like metal. However, old plastic can become fragile and break when you try to turn it. If it breaks, you might need to carefully cut the rest of it off.
Q: How do I deal with a drain pipe that is in the way?
A: Sink drains can block your view and access. You might need to temporarily loosen or remove a part of the drain pipe (like a trap) to get better access to the faucet nuts. Place a bucket under the drain first, as water will be in the trap. Be ready to put it back together properly to prevent leaks.
Q: Do I need to replace the supply lines?
A: It is highly recommended. Old supply lines can fail and cause big leaks. New faucets often come with new lines or require specific types. Even if they seem okay, replacing them provides peace of mind. Make sure the new lines are the correct length and have the right size fittings for your new faucet and your existing shut-off valves.
Q: What is the crescent washer for?
A: The crescent washer is part of the mounting system. It often sits between the U-shaped bracket and the nut. Its shape allows it to fit around the supply lines passing through the sink hole. It helps distribute the pressure from the tightening nut evenly across the U-shaped bracket, helping to secure the faucet firmly to the sink.
Q: My old faucet is heavily corroded faucet. Is it safe to try removing it myself?
A: You can try, but be very careful. If parts are badly rusted or fused, forcing them can break pipes or valves. If penetrating oil and steady pressure do not work, or if you worry about causing damage, it is better to call a plumber. They have ways to deal with severely stuck plumbing parts.
Q: After removing the faucet, how do I prepare for replacing kitchen faucet?
A: Clean the sink surface where the new faucet will sit. Remove all old caulk, putty, and grime. Read the instructions for your new faucet carefully. It will show you how its specific parts fit together and how to install it in the clean sink hole. Make sure you have all the needed parts and maybe new supply lines.
Q: I accidentally bent a pipe under the sink. What should I do?
A: Turn off the water immediately! If you only slightly bent a metal pipe, it might still be okay, but any damage could cause a leak later. If the bend is significant, or it’s a plastic pipe that cracked, the damaged section needs to be replaced. If you are unsure how to do this, call a plumber right away to avoid water damage.
Removing a kitchen faucet with a U-shaped bracket is a common home repair task. By following these steps and using the right tools, you can get the job done and be ready to install your new faucet.
