How to Install a Delta Kitchen Faucet?

The kitchen, often referred to as the heart of the home, is a hub of daily activity. A critical component of this space is the kitchen faucet – an item that combines functionality and aesthetics. When it comes to selecting a kitchen faucet, Delta faucets stand out for their quality, durability, and style.

If you’ve chosen a Delta kitchen faucet and are ready to install it yourself, this guide will walk you through the process step-by-step. By the end, you’ll not only save on installation costs but also gain a sense of accomplishment and a deeper understanding of your home’s plumbing system.

Understanding Delta Kitchen Faucets

Before diving into the installation process, let’s understand what makes Delta kitchen faucets a preferred choice. Delta faucets are known for their innovative designs, such as the Touch2O technology that allows you to turn the faucet on and off with just a touch.

They also offer a range of styles and finishes to match any kitchen decor. The durability of Delta faucets is backed by a comprehensive warranty, making them a long-term investment for your home.

Tools and Materials Needed

To install a Delta kitchen faucet, you need the right tools and materials. Gather these items before starting the installation:

  • Adjustable wrench
  • Basin wrench
  • Plumber’s tape
  • Screwdriver
  • Delta kitchen faucet kit (includes the faucet and necessary mounting hardware)
  • Towels or rags
  • Bucket
  • Safety glasses (recommended)

Preparation: Safety and Convenience

Before starting, ensure your working area is safe and convenient. Clear out the space under the sink to provide ample room for maneuvering.

Place a towel or a bucket underneath to catch any water drips. It’s also a good idea to wear safety glasses to protect your eyes from any debris or drips.

Steps to Install a Delta Kitchen Faucet

Step 1: Turn Off Water Supply

The first and most crucial step is to turn off the water supply to prevent any accidental water spillage. Locate the water supply valves under the sink and turn them clockwise to shut them off.

Once done, open the existing faucet to drain out any residual water and release pressure from the lines.

Step 2: Removing the Old Faucet

Begin by disconnecting the water supply lines using an adjustable wrench. Keep a towel handy to absorb any escaping water.

Next, use a basin wrench to remove the nuts that secure the faucet. Once loosened, carefully lift the old faucet out from the top of the sink.

This step might require some patience and gentle maneuvering.

Step 3: Cleaning the Area

Cleaning the sink surface where the old faucet was seated is crucial for ensuring a proper seal and fit for the new faucet.

Any residue, old plumber’s putty, or grime should be thoroughly cleaned off.

Step 4: Installing the New Delta Faucet

Now comes the exciting part – installing your new Delta kitchen faucet. Follow these steps:

  • Position the New Faucet: Carefully feed the lines of the new faucet through the designated holes in the sink. Position the faucet so it sits evenly on the sink.
  • Secure the Faucet Underneath: Under the sink, place the washers and nuts that came with the faucet kit on the faucet tails. Tighten them to secure the faucet in place. You might need to adjust the faucet from above to ensure it’s straight.
  • Connect the Water Lines: Wrap the plumber’s tape around the threads of the water lines for a watertight seal. Connect the water lines to the faucet and use an adjustable wrench to tighten them. Be cautious not to over tighten.

Step 5: Connecting to the Water Supply

Connect the faucet’s water lines to the shut-off valves under the sink.

Again, use the wrench for tightening but avoid overdoing it, as it can damage the lines.

Step 6: Checking for Leaks

This step is crucial for ensuring the installation is successful. Slowly turn on the water supply valves and check for any leaks around the faucet and connections.

If you spot a leak, tighten the connections a bit more. Sometimes, adjusting the washer or reapplying the plumber’s tape might be necessary.

Step 7: Testing the Faucet

Finally, turn on the faucet to check its operation. Ensure that both hot and cold water flow correctly and that the faucet handles work smoothly.

Check the spray head functionality if your model includes one.

Tips and Troubleshooting

Here are some additional tips and troubleshooting advice:

  • Taking Photos: Before removing the old faucet, take photos for reference. This can be particularly helpful when connecting the water lines to the new faucet.
  • Dealing with Hard-to-Reach Areas: A basin wrench is invaluable for tightening and loosening nuts in tight spaces behind the sink.
  • If a Leak Persists: If you’re unable to stop a leak after several adjustments, it might be wise to seek professional help. Persistent leaks can lead to water damage.


Installing a Delta kitchen faucet is a fulfilling DIY project that enhances your kitchen’s functionality and style. By following this detailed guide, you can ensure a smooth installation process.
