How to Replace Your Kitchen Faucet Without a Plumber

Replacing a faulty or outdated kitchen faucet can seem like a daunting task for DIY homeowners. However, with the right preparation and tools, it is possible to swap out your kitchen faucet yourself without having to call in a professional plumber.

With some basic plumbing know-how and a little bit of elbow grease, you can upgrade your kitchen faucet on your own time and budget. By following the instructions outlined here, you'll gain the confidence to take on this project and enjoy your updated, fully-functional kitchen again in no time.

When Is It Time for a New Kitchen Faucet?

Your kitchen faucet sees heavy daily use, so it's no surprise that it may need replacing every decade or so. Here are some signs that indicate it's time to upgrade your kitchen faucet:

• Frequent leaks or drips. This usually signals worn washers or O-rings.
• Low water flow. Clogged aerator screens or supply lines reduce water pressure.
• Loose faucet. Mounting nuts underneath have likely come loose.
• Hard-to-turn handles. Mineral deposits limit handle rotation.
• Cosmetic issues. Scratches, stains, and missing parts detract from look.

Replacing the faucet is often cheaper than continually repairing these common issues. Investing in a higher-quality faucet also buys you improved features and longevity.

Gathering Necessary Tools and Materials

Installing a new kitchen faucet requires just a few tools and materials:

• Basin wrench - For loosening nuts securing the old faucet
• Adjustable wrench - For tightening supply line connections
• Plumber's putty - For sealing between new faucet and sink
• Flashlight - For seeing up into the sink cabinet area
• Cloths - For cleaning up workspace afterwards

You'll also need the new faucet and compatible supply lines. Having all tools and materials ready beforehand streamlines the replacement process.

Prepping for Faucet Removal

With your new faucet and tools on hand, it's time to start prepping for removing the old unit. This critical first step will make the rest of the installation much smoother.

Turn Off Water Supply

Locate the shutoff valves controlling water flow to the kitchen sink and turn them clockwise to the "Off" position. This prevents water from spraying out during faucet removal. Try loosening the valves first if they are stiff.

Disconnect Supply Lines

Under the sink, use an adjustable wrench to loosen the nuts securing the supply lines to the faucet tailpieces. Unscrewing these connections allows the faucet to be freely lifted out.

Remove Mounting Hardware

Use a basin wrench to remove the mounting nuts holding the faucet to the underside of the sink. Removing this hardware is necessary for detaching the unit.

With the water supply cut off and all connecting hardware detached, the old faucet is ready for removal.

Removing the Old Kitchen Faucet

Carefully work the faucet loose and remove it from the sink. Then give the sink area a thorough cleaning to eliminate old putty and grime before installing the new faucet.

Detach Faucet from Sink

Lift the faucet up and out of the sink holes. Wiggle it gently side to side while lifting to help break the seal. Place a towel in the sink so you don't drop any small parts down the drain.

Clean Sink Surface

Use a plastic putty knife to scrape off the old plumber's putty from around the faucet holes. Remove any debris, grime or excess putty until only the bare sink surface remains. Proper cleaning prevents leaks.

Now the sink is prepped and ready for the new faucet installation.

Installing the New Kitchen Faucet

With the old unit removed and workspace cleaned, it's time to install the fresh faucet. Carefully follow the steps below to ensure it's securely mounted and properly connected.

Prepare Faucet and Connections

Read the manufacturer's instructions to prepare the new faucet for mounting. Install any parts required and apply plumber's putty if needed.

Secure Faucet to Sink

Lower the new faucet through the sink holes, then hand tighten the mounting nuts previously removed to hold it in place.

Connect Water Supply Lines

Attach the supply lines to the faucet tailpieces and finger tighten. Then use an adjustable wrench to finish tightening the connections.

Leak Check

Turn the water supply back on and inspect closely for any drips or leaks at supply line connections. Tighten as needed.

If no leaks are observed, the new faucet installation is complete and ready for everyday use.

Finishing Touches

With functional faucet installation complete, put the finishing aesthetic touches on the project.

Replace Accessories

If needed, switch out the sink strainer and install the new manufacturer-provided aerator. This optimizes faucet performance.

Clean Up

Remove any tools and leftover materials, then tidy up the sink area. Wipe down the new faucet to remove any fingerprints.

Test New Faucet

Turn faucet handles on and off and use the sprayer to ensure proper operation. Also check that all connections remain leak-free.

Enjoy your upgraded, professional-looking kitchen faucet!

Troubleshooting Common Problems

Despite best efforts, you may encounter minor issues with the new faucet. Refer to these tips for quickly resolving them.

Leaks

If leaks occur, tighten nuts or supply line connections with an adjustable wrench. Replace worn washers or O-rings if needed.

Low Water Pressure

Low pressure usually means a clogged aerator screen. Unscrew the aerator and clean out any debris.

Loose Faucet

Tighten the mounting nuts underneath the sink if the faucet moves around after installation.
