Key Takeaways

• Shut off hot and cold water valves, relieve pressure, and place a bucket beneath the sink.
• Disconnect supply lines, remove mounting hardware, and lift out the old faucet.
• Clean and dry the sink’s mounting surface, removing old sealant, putty, and debris.
• Position the new faucet with its gasket, center it, and tighten mounting hardware evenly.
• Reconnect hot and cold supply lines, reopen valves gradually, flush the faucet, and check for leaks.

Check Faucet Fit and Gather Your Tools

Before you remove the old faucet, confirm that the new one fits your sink’s mounting holes and plumbing connections. Check whether your sink has one, two, three, or four holes, then compare that layout with the faucet’s specifications.

Confirm your new faucet matches the sink’s mounting-hole layout and plumbing connections before removing the old one.

If the faucet needs an escutcheon plate or adapter, verify that it’s included or purchase it separately. Measure the space beneath the sink to ensure the supply hoses and mounting hardware will fit comfortably.

Review the manufacturer’s instructions for connection sizes, required parts, and installation limits. Good faucet compatibility prevents delays and helps you avoid returns.

Next, prepare a tool checklist before you begin. Gather an adjustable wrench, basin wrench, screwdriver, plumber’s tape, bucket, flashlight, and cleaning cloth.

You may also need penetrating oil for stubborn hardware, a utility knife for packaging, and a ruler for measurements. Keep every tool within reach, and organize the faucet’s components on a towel so you can identify washers, nuts, and seals quickly.

Shut Off Water and Disconnect the Lines

Turn off the hot- and cold-water shutoff valves beneath the sink by turning them clockwise until they stop. Open the faucet briefly to release remaining Water pressure, then close it. Place a towel and shallow bowl under the connections to catch drips.

1. Identify the hot and cold supply lines before loosening anything.
2. Use an adjustable wrench to turn each compression nut counterclockwise.
3. Keep a second wrench on the shutoff valve so you don’t twist the plumbing.
4. Remove the lines from the faucet’s threaded stems and let them drain into the bowl.

If a valve won’t close fully, shut off the home’s main water supply and open the faucet again. Check each connection for seepage, corrosion, or damaged threads.

Different Faucet models may use flexible hoses, rigid tubes, or quick-connect fittings, so follow the connection style rather than forcing it. Cap or plug open supply lines temporarily if necessary, and keep the workspace dry and organized.

Don’t disturb the faucet mounting hardware yet. You’ll handle that in the next step.

Remove the Old Kitchen Faucet

With the water supply shut off, place a bucket beneath the sink to catch any remaining water. Then, disconnect the supply lines from the faucet. Next, loosen the mounting hardware and lift out the old faucet.

Shut Off Water Supply

Start by shutting off the hot and cold supply valves beneath the sink, turning each handle clockwise until it stops. This stops water pressure before you remove the old faucet and helps prevent an unexpected spray.

1. Open the faucet briefly to release trapped pressure.
2. Place a shallow bucket beneath the valves to catch residual water.
3. Check both handles, ensuring neither turns farther counterclockwise.
4. Keep a towel nearby for damp surfaces and minor drips.

Wait several seconds, then open and close the faucet once more to confirm the supply has stopped. If water continues flowing, locate your home’s main shutoff valve and close it.

Before proceeding, inspect the faucet materials and surrounding connections for corrosion or mineral buildup. Don’t force stuck valves; gentle movement protects the plumbing.

Once the sink area stays dry, you’re ready for the next removal step, without disconnecting anything yet.

Disconnect Supply Lines

How do you disconnect the supply lines without spilling water everywhere? First, confirm both shutoff valves are closed. Open the faucet briefly to release remaining water pressure, then close it again.

Place a bucket and towel beneath the connections to catch trapped water. Using an adjustable wrench, turn each supply-line nut counterclockwise where it connects to the shutoff valve.

Hold the valve steady with another wrench so you don’t twist or damage the plumbing. Let each line drain into the bucket, and wipe the threads clean afterward.

If a nut won’t budge, apply penetrating oil and wait several minutes rather than forcing it. Label the hot and cold lines if needed, especially when checking faucet compatibility for the replacement.

Keep the disconnected lines supported, and inspect them for corrosion or cracks before disposal.

Loosen Mounting Hardware

Once the supply lines are disconnected, loosen the mounting hardware beneath the sink. Clear stored items from the cabinet so you can work comfortably. Use a basin wrench, adjustable wrench, or deep socket, depending on the faucet materials and nut design.

1. Find the retaining nuts, mounting bracket, and washers beneath the faucet.
2. Hold the faucet body above the sink to prevent twisting as you loosen each nut.
3. Turn stubborn nuts counterclockwise, applying penetrating oil if mineral buildup or corrosion resists removal.
4. Remove the nuts, washers, and mounting bracket, then lift the old faucet from the sink.

Scrape away old plumber’s putty or silicone around the openings. Wipe the sink surface clean with a cloth.

Keep removed hardware together until disposal, since sharp edges may damage plumbing components or your hands during cleanup. Wear gloves and eye protection while working underneath the sink to avoid grime and debris.

Clean and Prepare the Sink

Before you install the new faucet, clear everything away from the sink and turn off the water supply. Remove any debris, then clean the mounting surface thoroughly.

Clear the Sink Area

Start with a clear, dry workspace by removing dishes, sponges, soap, and anything stored beneath the sink. This gives you room to work and helps you spot leaks, grime, or loose items around the faucet base.

1. Place removed items on a towel or countertop, grouping them for easy return.
2. Wipe the sink basin, rim, and surrounding counter with suitable cleaning supplies.
3. Scrub away mineral deposits and dried residue near the faucet holes.
4. Dry every surface thoroughly with a clean cloth.

Use this opportunity to improve sink organization. Discard empty containers, relocate rarely used products, and keep the cabinet floor open for tools or a small towel.

Remove the drain stopper or rack if either blocks access, then set each piece aside safely. Good preparation keeps parts visible and prevents clutter from slowing your faucet replacement.

Shut Off Water Supply

Turn off the hot- and cold-water shutoff valves beneath the sink by turning each handle clockwise until it stops. Open the faucet to release trapped Water pressure, and let remaining water drain into the basin.

If water continues flowing, close the home’s main shutoff valve before proceeding. Place a bucket beneath the supply connections to catch drips, then loosen each connection carefully with an adjustable wrench.

Keep a towel nearby for spills, and don’t force corroded fittings, which could damage the valve or supply line. Check the Faucet material and manufacturer’s care guidance before applying any cleaner or tool.

Once the lines stop dripping, plug the drain opening or cover it with a cloth to prevent small parts from falling inside. Keep the cabinet dry and well lit while you work.

Clean Mounting Surface

With the water supply off, remove debris, old plumber’s putty, and sealant from the sink’s mounting surface using a plastic scraper or nonabrasive pad. This surface preparation helps your new faucet sit flat and prevents leaks.

1. Wipe the area with warm, soapy water to loosen grease and grime.
2. Scrub stubborn residue gently with a nylon brush. Don’t scratch stainless steel or damage porcelain.
3. Use a cloth dampened with rubbing alcohol to remove remaining oil, then let the surface dry completely.
4. Inspect the opening and surrounding sink for chips, cracks, or corrosion before installing the faucet.

Remove all debris around the faucet hole, including underneath the rim if accessible. A clean, dry surface allows the gasket or plumber’s putty to seal properly.

Avoid harsh abrasives, wire brushes, and excessive force during cleaning.

Mount and Align the New Faucet

Once the old faucet is removed, lower the new faucet’s supply lines through the mounting hole and seat its base or gasket flat against the sink. During faucet installation, check that the gasket covers the opening completely and that the faucet sits securely without rocking.

From above, center the spout between the sink basins, or aim it toward the middle of a single basin. Position the handle or handles where you can operate them comfortably without contacting the backsplash.

Look beneath the sink to confirm the retaining plate or bracket rests evenly against the underside. Don’t force the faucet into position. Lift it slightly, adjust the gasket, and reseat it if necessary.

Before securing the fixture, use a level or measure the spacing from each sink edge to verify mounting alignment. Keep the faucet straight while you prepare the hardware for the next step.

Wipe away any debris trapped beneath the base, then recheck its orientation from every angle.

Attach Supply Lines and Tighten the Faucet

Connect each braided supply line to the matching shutoff valve, keeping the hot and cold lines on their correct sides. Check Supply line compatibility before attaching anything, since connection sizes and thread types must match.

Hand-tighten each connector first to prevent cross-threading, then use an adjustable wrench for a snug fit. Don’t overtighten; excessive force can damage the valve or fitting.

1. Feed the hot line to the hot shutoff valve and the cold line to the cold valve.
2. Confirm each gasket sits inside its connector before tightening.
3. Hold the faucet steady while you secure the connections underneath.
4. Tighten the mounting nuts evenly, following the faucet manufacturer’s instructions.

Next, inspect the Faucet mounting hardware. Ensure the mounting plate, washers, and nuts sit in their intended positions, then tighten the nuts until the faucet feels firmly anchored.

Keep the faucet centered and aligned as you work. Wipe away fingerprints or debris around the connections, and organize the lines so they don’t kink, twist, or press against sharp cabinet edges.

Turn On Water and Check for Leaks

Slowly open the hot and cold shutoff valves, turning each handle counterclockwise while watching the connections for drips. Restore water pressure gradually to protect the new faucet and supply lines.

Once both valves are fully open, lift the faucet handle and let water run for about a minute. This flushes out debris that may have entered during installation.

Move the handle through hot and cold settings, checking that water flows smoothly and the temperature changes properly.

For leak detection, inspect every connection beneath the sink, including the shutoff valves, supply-line nuts, and faucet mounting area. Dry each fitting with a clean paper towel, then watch for fresh moisture.

If you find a drip, turn off the affected valve, tighten the connection slightly, and test again. Don’t overtighten, since excessive force can damage threads or seals.

Also check the spout, sprayer hose, and drain area while the faucet runs. Afterward, wipe everything dry and recheck the connections after several minutes.

Frequently Asked Questions

How Often Should a Kitchen Faucet Be Replaced?

You should typically replace a kitchen faucet every 10–15 years, depending on its quality, usage, and condition. Your faucet lifespan may shorten if you notice persistent leaks, corrosion, declining water pressure, loose handles, or frequent repairs.
