How to Replace a Kitchen Faucet

Plan Before You Remove the Old Faucet

Replacing a kitchen faucet is a manageable DIY project, but the existing plumbing can create surprises. Check the water lines and connections for corrosion before starting, and shut off the water supply at the shutoff valves under the sink.

Match the New Faucet to the Sink

Count the mounting holes in the sink or countertop before buying a replacement. If the new faucet uses fewer holes than the sink, you can install a deck plate to cover the extra openings. If you are changing from a one-hole faucet to a multi-hole faucet, the sink may need additional drilling or professional help.

Check Spout Height and Reach

The new faucet should clear your tallest pot and reach the center of the sink without being so tall that water splashes outside the bowl. Measure the space under any cabinets or shelves above the sink as well.

Basic Replacement Steps

1. Turn off the hot and cold water supply valves.
2. Open the old faucet to release remaining pressure.
3. Disconnect the supply lines with a basin wrench.
4. Remove the mounting nuts holding the old faucet to the sink.
5. Clean the sink surface around the mounting holes.
6. Install the new faucet according to the manufacturer’s instructions.
7. Reconnect the water supply and tighten the connections carefully.
8. Turn on the water and check for leaks at all joints.

When to Call a Plumber

• The shutoff valves are old or leaking.
• The existing holes do not match the new faucet.
• The water lines are corroded or difficult to reach.
• You are changing the sink configuration at the same time.
