Understanding Your Faucet

Different Types of Faucets

Faucets come in various types, each with its own installation method. The most common types include:

  • Compression Faucets: Use separate hot and cold handles to control water flow.
  • Ball Faucets: Feature a single handle that moves over a rounded ball cap.
  • Cartridge Faucets: Have a movable stem cartridge that controls water flow.
  • Disc Faucets: Use a pair of ceramic discs to regulate water flow and temperature.

Identifying your current faucet type is crucial for selecting a compatible replacement.

Choosing the Right Replacement Faucet

Consider the following factors when choosing a new faucet:

  • Style and Finish: Match your kitchen sink or bathroom decor for a cohesive look.
  • Functionality: Decide between single-handle or double-handle faucets based on your preference.
  • Mounting Options: Ensure your new faucet is compatible with your sink’s mounting holes.


Shutting Off the Water Supply

Before you begin, shut off the water supply to the faucet. Locate the shut-off valves under the sink and turn them clockwise to close. If there are no shut-off valves, turn off the main water supply to your home.

Preparing the Workspace

Clear the area under the sink to create a comfortable workspace. Place a bucket underneath to catch any residual water and lay down towels to protect your cabinets and floor from potential water damage.

Step-by-Step Guide to Replacing the Faucet

Removing the Old Faucet

  1. Disconnect the Water Supply Lines: Use an adjustable wrench to loosen the nuts connecting the supply lines to the faucet. Carefully remove the lines and place them in the bucket.
  2. Remove the Mounting Nuts: Using a basin wrench, loosen and remove the mounting nuts that secure the faucet to the sink.
  3. Detach the Faucet: Lift the old faucet out of the mounting holes and clean the area around the sink to remove any debris or residue.

Installing the New Faucet

  1. Insert the Faucet: Place the new faucet into the mounting holes, ensuring it’s aligned correctly.
  2. Secure the Faucet: From underneath the sink, attach the mounting nuts to secure the faucet in place. Tighten them with a basin wrench.
  3. Connect the Water Supply Lines: Attach the supply lines to the new faucet, applying plumber’s tape to the threads for a secure seal. Tighten the connections with an adjustable wrench.
  4. Test the Faucet: Turn on the water supply and check for leaks. If any leaks are detected, tighten the connections further until they stop.

Testing the New Faucet and Checking for Leaks

Turn on the faucet and let the water run for a few minutes. Check all connections for leaks and ensure the water flows smoothly. If everything is in order, clean up your workspace and enjoy your new faucet.

Common Issues and Solutions
