How to Install a 3-Way Kitchen Tap: A Step-by-Step Guide

Mar 8, 2024 Liliumfaucet

Installing a three-way kitchen faucet may improve your space's usability and convenience, whether you're remodeling your kitchen or just changing out your outdated faucet. These faucets are a popular option for contemporary kitchens since they can pull hot, cold, and filtered water from a single fixture. We'll take you through the process of installing a three-way kitchen faucet in this tutorial, making sure the installation goes smoothly and successfully.

Preparation before installation

Assemble the installation-related equipment and supplies before you start. Three tools are required: a monkey wrench, pipe tape, and an Allen wrench (2.5mm). It's also crucial to shut off the kitchen's water supply before beginning the installation. To close the shutdown valve, locate it under the sink and crank it clockwise.

 Install the faucet on the sink

Install the faucet on the sink

After purchasing a three-way faucet, place it over the countertop or sink. Before proceeding, make sure everything is centered and well-aligned. Attach the supply lines to the faucet's corresponding cold, hot, and filtered water inlets. To guarantee a watertight seal, apply the plumber's tape to the supply pipe's threaded end.

Fit the faucet onto the sink or countertop using the spacers, mounting hardware, and other accessories that come with it. Tighten the mounting nuts under the sink or countertop using an adjustable wrench. Take care not to overtighten it, as this might harm the mounting surface or the fixture.

Connect 3-Way function

One of the crucial phases in installing a 3-way kitchen faucet is connecting the function. Leak prevention and smooth water flow are ensured when hot, cold, and filtered water pipes are connected to faucets properly. The steps to link the 3-way function are as follows:

  1. Prepare the sink or countertop by making sure the faucet is mounted correctly.
  2. Make sure the pipes for your hot, cold, and filtered water are long enough to reach the faucet input.
  3. To guarantee a tight seal on the connection, prepare the plumber's tape.
  4. Attach the hot water pipe: Attach the hot water pipe to the faucet's "HOT" input. Verify that there are no leaks and that the connections are tight. Lightly tighten the connection with an adjustment wrench, being careful not to harm the faucet or the connection.
  5. Link the cold water supply: Attach the cold water supply to the faucet's "COLD" input. Once again, confirm that there are no leaks and that the connections are snug. The connection may be slightly tightened with an adjustment wrench.
  6. Attach the filtered water hose: Attach the filtered water line to the "FILTERED" faucet input. Once again, confirm that there are no leaks and that the connections are snug. The connection may be slightly tightened with an adjustment wrench.
  7. Examine the connections: Make sure all connections are secure and leak-free by checking each one.
    If leaks are discovered, either reapply the plumber's tape or tighten the connection even more using an adjustment wrench.

Testing and finishing

After making sure all connections are tight, turn on the faucet and check that the heat, cold, and filtration functions are operating as intended. Look for any leaks or drips and fix them right away. After the installation is satisfactory, remove any leftover plumber's tape or debris and enjoy your brand-new three-way kitchen faucet.

Maintenance tips for kitchen three-way faucets

One essential piece of equipment in the contemporary kitchen is the three-way faucet. Regular maintenance is necessary to guarantee steady operation over the long term and preserve excellent functioning conditions. Here are a few standard upkeep guidelines for kitchen faucets with three settings:

  • Clean often: Keeping your faucets clean will help prevent scale and debris from building up and preserve their finish and aesthetic. Make sure to rinse well after cleaning the faucet's surface with a soft cloth and mild detergent.
  • Clean nozzles and aerators: Clogged nozzles or aerators may be the reason for a weak or uneven water flow. This issue may be resolved by routinely inspecting and cleaning nozzles and aerators. Remove the nozzle and aerator, soak them in detergent-infused water, brush them clean with a soft brush, rinse them with fresh water, and replace them.
  • Seals and connections: Inspect your faucet's seals and connections on a regular basis for leaks. If leaks are discovered, fix them right away by tightening connections or replacing seals to protect the faucet and nearby properties from water damage.
  • Maintain your filter: Changing the filter on your faucet, if it has one, is essential to maintaining clean water. Replacing the filter every three to six months is typically advised, depending on water quality and use frequency.
  • Avoid applying too much force: To prevent internal faucet components from being damaged, do not spin the faucet's handle or nozzle too much while using it. The handle may be turned only a little bit to adjust the temperature and flow strength.
  • Prevent freezing: You may take certain steps, such as putting insulating materials around the faucets or utilizing heaters, to keep the water pipes in the faucets from freezing during the chilly winter months.



Adding flair and usefulness to your kitchen with a three-way kitchen faucet installation is a satisfying do-it-yourself job. You may install your new faucet with confidence, knowing you've done it properly, if you follow our detailed instructions. To maintain the best possible condition for your faucet, always remember to do routine maintenance on it. If you run into any problems during installation, get expert assistance.
