Getting Ready: What You’ll Need
Before you start to dismantle your Delta faucet, gather your tools and supplies. Having everything on hand will make the job smoother and prevent frustrating trips to the hardware store mid-project.
Essential Tools
- Adjustable Wrenches (2): You’ll need these for gripping and turning nuts and fittings. Having two allows you to hold one part steady while turning another.
- Basin Wrench: This specialized tool is a lifesaver for reaching those awkward nuts located above the sink basin, often in tight spaces.
- Pliers: A good pair of slip-joint pliers can be helpful for various tasks, including gripping stubborn parts.
- Screwdrivers: You’ll likely need both Phillips head and flathead screwdrivers.
- Bucket or Towels: To catch any residual water that might drip out when you disconnect the water lines.
- Safety Glasses: Protect your eyes from falling debris or splashing water.
- Work Gloves: To protect your hands and improve grip.
- Penetrating Oil (Optional): If fittings are old or corroded, this can help loosen them.
- Flashlight or Headlamp: The area under the sink can be dark.
- Rags or Old Towels: For cleaning up any spills.
Preparing Your Workspace
A little preparation goes a long way. Clear out everything from under your sink to give yourself ample room to work. Place a bucket or a thick layer of old towels beneath the water supply lines and faucet connections to catch any drips.
Step-by-Step Guide to Uninstall a Delta Kitchen Faucet
Now, let’s get started on how to uninstall your Delta kitchen faucet. Follow these steps carefully for a successful removal.
Step 1: Turn Off the Water Supply
This is the most crucial first step. You must turn off the water to prevent flooding.
Locating the Shut-Off Valves
Look under your sink for two small valves, one connected to the hot water supply and one to the cold. These are usually located on the wall or directly attached to the pipes coming from the floor. They often have small handles or knobs.
Closing the Valves
To turn off the water, turn the handles of both the hot and cold water valves clockwise until they are snug. Don’t overtighten them, as this can damage the valve.
Releasing Residual Pressure
After closing the valves, turn on your faucet to drain any water left in the lines. Let it run until no more water comes out. This releases the pressure in the system.
Step 2: Disconnect the Water Lines
With the water off, you can now disconnect the flexible supply lines from the faucet’s shanks.
Identifying the Connections
Under the sink, you’ll see where the hot and cold water supply lines connect to the bottom of the faucet assembly. These connections are typically made with threaded nuts.
Detaching the Lines
- Place your bucket or towels under the connections.
- Use an adjustable wrench to loosen the nuts connecting the supply lines to the faucet. Turn the nuts counter-clockwise.
- If the faucet itself starts to spin, use a second adjustable wrench to hold the faucet shank steady while you loosen the nut on the supply line.
- Once loose, carefully detach the supply lines. Some residual water may drip out, so be prepared.
Step 3: Remove Faucet Handles (If Applicable)
Many Delta faucets have separate handles. You’ll need to remove these before you can unmount the main faucet body.
Finding the Set Screw
- Look for a small set screw on the back or underside of the faucet handle. This screw secures the handle to the valve stem.
- The screw is often hidden behind a decorative cap or plug. You may need to gently pry off a small decorative cover (often marked with blue for cold and red for hot) using a flathead screwdriver or a utility knife.
Loosening the Set Screw
- Use the appropriate screwdriver (usually a Phillips head, but sometimes a hex wrench or Allen key) to loosen the set screw. Turn it counter-clockwise.
- Once the set screw is loose enough, the handle should lift straight up and off the valve stem.
Removing the Handle Cover/Bonnet Nut
- After removing the handle, you might see a decorative cover or a bonnet nut holding the valve cartridge in place.
- This cover can often be unscrewed by hand. If it’s tight, use pliers or an adjustable wrench to carefully unscrew it.
Step 4: Remove the Faucet Base and Main Body
This is where you’ll detach the main part of the faucet from the sink.
Locating the Mounting Nuts
Under the sink, look directly above where the faucet is mounted on the sink. You’ll find large nuts (often called mounting nuts or lock nuts) that hold the faucet in place. There might be one or two of these, depending on your faucet model.
Using the Basin Wrench
- The basin wrench is your best friend here. Its long shaft and pivoting jaw are designed to reach and grip these nuts in tight spaces.
- Position the jaw of the basin wrench onto one of the mounting nuts.
- Turn the handle of the basin wrench counter-clockwise to loosen the nut. This can take some effort, especially if they are old or corroded.
- If the faucet body itself starts to twist, use your other adjustable wrench to hold the faucet shank steady from above the sink if possible, or have a helper stabilize it.
- Once the nut is loose, remove it completely. Repeat this process for any other mounting nuts.
Separating the Faucet Body
After all mounting nuts and supply lines are disconnected, the faucet body should be loose. You may need to gently wiggle it to break any old sealant. Lift the entire faucet assembly up and out from the top of the sink.
Step 5: Clean the Mounting Surface
Once the old faucet is removed, you’ll likely find residue from old plumber’s putty or sealant on the sink surface.
Removing Old Putty
- Use a putty knife or a plastic scraper to carefully scrape away the old plumber’s putty or sealant. Be gentle to avoid scratching the sink surface, especially if it’s a delicate material like porcelain.
- Clean the area thoroughly with a mild cleaner and a cloth. A clean surface is essential for a good seal with your new faucet.
Common Challenges and How to Solve Them
Even with the best preparation, you might encounter a few hiccups. Here’s how to handle some common issues when you need to remove a Delta faucet.
Stubborn or Corroded Nuts
If the mounting nuts or supply line fittings are corroded and won’t budge:
- Penetrating Oil: Apply a penetrating oil (like WD-40) to the threads. Let it sit for 15-30 minutes, or even longer for very stubborn cases. Reapply if necessary. Then, try loosening the nuts again with your wrench.
- Heat (Use with Extreme Caution): In rare cases, a heat gun applied briefly to the nut (not the surrounding pipes) can help expand the metal slightly, making it easier to loosen. This is a risky method and should only be attempted if you are comfortable with it and can ensure no flammable materials are nearby. Water in the pipes will absorb some heat, but be very careful not to overheat plastic components.
- Nut Splitter: If all else fails, a nut splitter tool can be used to carefully break the nut without damaging the faucet shank.
Leaking Shut-Off Valves
If your shut-off valves themselves are leaking when you try to turn them off:
- Tighten Slightly: Try tightening the valve handle just a little bit more.
- Replace the Valve: If they continue to leak, you may need to replace the shut-off valves themselves. This is a more involved plumbing task and might require shutting off the main water supply to your house. If you’re not comfortable with this, it’s time to call a plumber.
Faucet Spinning While Loosening Nuts
This happens when the friction of turning the nut is greater than the friction holding the faucet in place.
- Second Wrench: As mentioned, use a second wrench to grip the faucet shank or base to keep it from turning.
- Helper: Ask someone to hold the faucet steady from above the sink while you work below.
Troubleshooting Frequently Asked Questions
Here are some common questions people have when they need to uninstall a Delta kitchen faucet.
What if I Can’t find the Shut-Off Valves?
If you cannot locate the shut-off valves under your sink, you will need to turn off the main water supply to your house. This valve is usually located in the basement, crawl space, garage, or near your water meter. Once the main water is off, open your faucet to drain the system.
What is Plumber’s Putty?
Plumber’s putty is a pliable, clay-like compound used to create a watertight seal around fixtures like faucets, drains, and strainers where they meet the sink or countertop. It’s often found around the base of the faucet.
How do I Detach the Sprayer Hose?
Many Delta faucets have a separate sprayer. The hose for the sprayer is usually attached to the underside of the faucet body with a quick-connect fitting or a threaded nut.
- Quick-Connect: Look for a plastic clip that you need to squeeze or a button to press to release the hose.
- Threaded Nut: Use an adjustable wrench to loosen the nut connecting the sprayer hose.
Do I Need to Remove the Entire Faucet Body?
Yes, to properly uninstall a Delta kitchen faucet, you will need to remove the entire faucet body from the sink. This includes detaching the handles, the spout, and any accompanying parts like sprayers.
What if My Faucet Has a Different Mounting System?
While the general steps are similar, some newer Delta faucets might use different mounting hardware. Always refer to the manufacturer’s installation and uninstall guide if you have it. However, the principles of turning off water, disconnecting lines, and unthreading mounting nuts remain consistent.
How to Remove Faucet Handles on Single-Handle Delta Faucets?
For single-handle Delta faucets, the handle is typically attached with a set screw, often located on the back or underside of the handle. You’ll need to remove a decorative cap to access this screw. Once the set screw is loosened, the handle should slide off the valve stem.
How do I Uninstall a Delta Faucet with a Deck Plate?
If your Delta faucet has a deck plate (a decorative trim piece that covers extra holes in the sink or countertop), you’ll need to unscrew the faucet body from the deck plate or the sink itself. The deck plate usually sits flush and is held in place by the same mounting nuts as the faucet. Once the faucet body is removed, the deck plate can be lifted off.
Reinstalling or Replacing Your Faucet
Once you have successfully managed to remove your Delta kitchen faucet, you’re ready for the next step.
Preparing for the New Faucet
- Ensure the sink surface is clean and dry.
- Check the faucet holes on your sink to ensure they match the new faucet you plan to install.
- Gather the installation parts and tools for your new faucet.
What if I’m Not Replacing the Faucet?
If you’re uninstalling for repairs, ensure you have the correct replacement parts. It’s often easier to replace worn-out parts like valve cartridges or O-rings while the faucet is disassembled.
