How to remove an old Kohler kitchen faucet?

Replacing an old kitchen faucet can revitalize the look of your kitchen and can be a satisfying DIY project. If you’ve got an old Kohler kitchen faucet that’s seen better days, removing it might seem daunting, but with the right guidance, it’s a task you can tackle on your own. In this article, we’ll walk you through the steps to remove your Kohler kitchen faucet and offer some plumbing tips to make the process smoother.

Before you begin, make sure you have the necessary tools on hand. You’ll likely need an adjustable wrench, a basin wrench, some plumber’s tape, and possibly a flashlight to help you see under the sink. Now, let’s dive into the removal process.

Step-by-Step Guide to Kohler Kitchen Faucet Removal

Step 1: Turn Off the Water Supply

The first and most important step is to shut off the water supply to your faucet to prevent any accidental flooding. Under your kitchen sink, you should find two valves—one for hot water and one for cold. Turn these valves clockwise until they’re tightly closed. To ensure the water is off, open the faucet and check that no water comes out.

Step 2: Disconnect the Water Supply Lines

Next, you’ll need to disconnect the water supply lines from the faucet. Place a bucket underneath to catch any water that may spill out. Using an adjustable wrench, loosen the nuts connecting the supply lines to the faucet. Once they’re loose, you can unscrew them by hand and gently pull the lines away from the faucet.

Step 3: Remove the Mounting Nuts

Kohler faucets are typically secured to the sink with mounting nuts located under the sink. These can be difficult to reach and may require a basin wrench. Use the basin wrench to loosen and remove the mounting nuts. If you encounter any resistance, spray some penetrating oil on them and allow it to sit for a few minutes before trying again.

Step 4: Lift Out the Old Faucet

With the mounting nuts removed, you should be able to lift the old faucet out from the top of the sink. If it doesn’t budge, check to make sure all connections have been fully disconnected. You may need to gently wiggle the faucet to free it from any caulk or sealant.

Troubleshooting Common Challenges

Dealing with Corrosion or Hard-to-Reach Nuts

One of the most common issues you might encounter when removing an old faucet is corrosion on the nuts or bolts that hold it in place. If these components are too tight or corroded, they can be tough to remove. Here are a few plumbing tips to help:

  • Apply a penetrating oil to the corroded parts and wait for it to break down the rust.
  • If the nuts are in a hard-to-reach place, a basin wrench with an extendable handle can provide the extra leverage you need.
  • In some cases, you may need to cut the nuts off with a hacksaw. Be very careful not to damage the sink or surrounding countertop.

Cleaning the Sink Area

Once the old faucet is out, take the opportunity to clean the area where it was mounted. Remove any rust, old plumber’s putty, or caulk with a putty knife or a similar tool. This will ensure a clean surface for installing a new faucet.

Plumbing Tips for a Successful Removal

  • Safety First: Wear gloves and safety goggles to protect your hands and eyes from sharp edges and debris.
  • Keep Organized: Place all removed parts in a container so you don’t lose any small components, especially if you plan to reuse them.
  • Take Photos: Before you begin, take a few pictures of the plumbing setup. This can be incredibly helpful if you need to remember how everything fits back together.
  • Go Slow: Take your time and don’t force any parts. If something isn’t moving, it’s better to figure out why than to risk breaking something.

Choosing a Replacement Kohler Faucet

Kohler offers a wide range of kitchen faucets with various styles and features. When choosing a replacement, consider the following:

  • Faucet Size and Fit: Make sure the new faucet will fit in the existing holes of your sink or countertop.
  • Features: Decide if you want added features such as a pull-out sprayer, touchless operation, or water filtration.
  • Finish: Choose a finish that matches your kitchen’s decor and other appliances.

Installing Your New Kohler Faucet

Once you’ve chosen a new Kohler faucet, it’s time to install it. The installation process is generally the reverse of the removal process:

  1. Place the New Faucet: Insert the new faucet into the mounting holes in your sink.
  2. Secure with Mounting Nuts: From under the sink, secure the faucet with the provided mounting nuts.
  3. Reconnect Water Supply Lines: Wrap the threads of the faucet’s tailpieces with plumber’s tape and reconnect the water supply lines.
  4. Turn on Water Supply: Once everything is connected, turn the water supply back on and check for leaks.
