Step-by-Step Guide

Materials Needed

Before starting the installation process, gather all necessary materials first. These materials may vary according to the type of faucet and the complexity of the installation. Here are some of the essential materials needed in installing a kitchen sink faucet:

  • Faucet and all its components
  • Faucet wrench or basin wrench
  • Adjustable wrench
  • Screwdrivers
  • Plumber’s putty
  • Teflon tape
  • Bucket or container for waste disposal

Tools List

In addition to the materials listed above, having the right tools is crucial to ensure a smooth installation process. Here is a list of recommended tools that may be needed in installing a kitchen sink faucet:

  • Drill
  • Hacksaw
  • Pipe cutter
  • Plumbers’ tape measure
  • Plunger
  • Soldering gun and solder
  • Tubing cutter


Before installing the new faucet, it is essential to prepare the work area and turn off the water supply. Here are the steps to prepare your kitchen sink for the installation process:

  1. Place the bucket or container beneath the sink to catch any water that may drip.
  2. Turn off the water supply under the sink – hot and cold – by turning the valves clockwise.
  3. Turn on the faucet to release any remaining water from the pipes. Then, allow the faucet to drain out and wait for any excess waste to drip into the container or bucket.

Removing the Old Faucet

The next step is to remove the old faucet. Here’s how:

  1. Disconnect the supply lines by turning the nuts counterclockwise. Be careful not to damage or bend the lines.
  2. Using the basin wrench or faucet wrench, loosen and remove the nuts, bolts, and screws that hold the faucet in place. Be mindful of any plastic pieces or seals that may also need to be removed.
  3. Detach the old faucet from the sink by lifting it up and off gently.

Mounting the New Faucet Base

Once the old faucet is removed, the next step is to mount the new faucet base. Here’s how:

  1. Put the gasket and mounting plate in place on the sink. Check the fit and placement of the gasket and plate to ensure they fit snugly together.
  2. Thread the mounting bolts through the plate’s holes, then the sink. Make sure that the bolts are tightened until they are snugly in place.
  3. Inspect the base deck of the faucet to ensure there is a rubber or plastic gasket that is placed over it.
  4. Position the base deck on the mounting plate and ensure that the mounting bolts extend through the matching holes on the base deck. Use the faucet wrench to tighten the mounting nuts under the sink until they are snug. Do not overtighten or damage the nuts.

Attaching the Supply Lines

The next step is to attach the supply lines to the new faucet. Here’s how:

  1. Apply plumber’s putty around the base of the faucet then insert the supply lines through the mounting hole on the sink. The putty helps create a watertight seal.
  2. Ensure the faucet is leveled before attaching the supply lines. Connect the mounting hardware and tighten the nuts around the mounting plate and the faucet.

Installing the Smooth-Surface Washer

To prevent leaks, it is essential to install a smooth-surface washer. Here’s how:

  1. Locate the smooth-surface washer from the kit that comes with the new faucet.
  2. Insert the washer into the top of the tailpiece that leads to the sink drain. Ensure that the green side of the washer is facing away from the nut you are securing it with to create a watertight seal.
  3. Further tighten the nut using slip-lock pliers. Be careful not to overtighten and damage the washer.

Securing the Faucet

The next step is to secure the faucet to the sink. Here is how:

  1. Ensure that the faucet is leveled and secure in place.
  2. Put a bead of plumber’s putty on the underside of the deck plate to help keep the faucet secure.
  3. Press the deck plate onto the sink, then tighten the mounting nuts from below until snugly in place.
  4. Use a clean, damp cloth to wipe away any excess putty that may be visible once the faucet is secured.

Attaching the Hot and Cold Water Supply

The next step is to reconnect the hot and cold water supply. Here’s how:

  1. Reconnect the supply lines to the hot and cold water valves. Tighten the nuts using the adjustable wrench until snug.
  2. Open the hot and cold valves, then turn on the water supply under the sink by turning on the shut-off valves.
  3. Turn on the faucet to test the water temperature and allow the water to run for a few minutes to flush any debris.

Testing the Faucet

The last step is to test the faucet to ensure that everything is working correctly. Here’s how:

  1. Run both hot and cold water to ensure they are functioning correctly.
  2. Check for any leaks or drips around the new faucet and clean the area after testing.
  3. Test the sprayer function, if applicable.
