Learning how to replace a kitchen faucet can be a helpful skill for homeowners who want to update the look of their kitchen, improve water flow, or fix an old fixture that has seen better days. A new faucet can make your sink area more attractive and more functional, especially if your current faucet leaks, sticks, sprays unpredictably, or looks like it has been through a few too many spaghetti nights. While faucet replacement is often a manageable project for handy homeowners, it still involves water lines, tight spaces, and a few plumbing details that deserve careful attention. We always recommend taking your time, using the right tools, and knowing when it is best to call a professional plumber. At Lance Maxwell Plumbing, we have helped many Jacksonville and Orange Park homeowners with kitchen faucet installation, repair, and upgrades, and we know that a smooth installation starts with a good plan.
Why Replace Your Kitchen Faucet?
A kitchen faucet gets used constantly, which means it naturally wears down over time. Even a high-quality faucet can eventually develop leaks, mineral buildup, loose handles, weak water pressure, or corrosion around the base. In some cases, replacing the faucet is more cost-effective than repeatedly repairing an older model, especially if the fixture is outdated or parts are difficult to find. A new faucet can also improve convenience with features like pull-down sprayers, touchless operation, better spray settings, and more efficient water flow. Of course, there is also the style factor, because a modern faucet can give your kitchen a quick refresh without requiring a full remodel.
Replacing your faucet may also help prevent larger plumbing issues. A slow leak under the sink can damage cabinets, flooring, and nearby materials if it goes unnoticed for too long. If the faucet connections are old, corroded, or poorly sealed, water can sneak into places where it definitely does not belong. That is why we encourage homeowners to inspect under the sink before beginning any faucet project. If you see mold, soft wood, rusted shutoff valves, or signs of previous leaks, it may be time to bring in a professional before things get messy.
Tools and Supplies You May Need
Before you start removing the old faucet, gather your tools and supplies. Nothing ruins a plumbing project faster than getting halfway through and realizing the tool you need is somewhere in the garage, under a box, behind the holiday decorations. Having everything ready helps the project go more smoothly and reduces the chance of accidental damage.
Common tools and supplies include:
- Adjustable wrench
- Basin wrench
- Bucket or small container
- Towels or rags
- Plumber’s tape
- Flashlight or work light
- Putty knife
- New kitchen faucet
- Supply lines, if not included with the faucet
- Plumber’s putty or silicone sealant, if recommended by the faucet manufacturer
- Safety glasses
It is also a good idea to read the manufacturer’s instructions before starting. Different faucet brands and models may have slightly different installation requirements. At Lance Maxwell Plumbing, we work with high-quality plumbing products from trusted brands like Delta, Kohler, and Moen, and each brand may include specific steps for securing the fixture, attaching supply lines, or sealing the faucet base. Reading the instructions first can save you from having to uninstall and reinstall parts later.
Step 1: Clear the Area Under the Sink
The first step is to clear everything out from under the kitchen sink. Remove cleaning supplies, trash bags, stored containers, and anything else that may be in the way. This gives you enough room to work and helps protect your belongings from water drips. Place towels on the cabinet floor and keep a bucket nearby to catch any remaining water from the supply lines. You will also want a flashlight, because the space under a sink is rarely known for its excellent lighting.
Once the area is clear, take a moment to inspect the plumbing. Look at the hot and cold water supply lines, shutoff valves, drain lines, and the underside of the faucet. If you notice heavy corrosion, damaged pipes, or valves that look too worn to turn safely, pause before moving forward. Forcing an old valve can cause it to break, which can quickly turn a simple faucet replacement into an emergency plumbing situation. When in doubt, it is better to call a trusted Jacksonville plumber than to gamble with a stubborn shutoff valve.
Step 2: Turn Off the Water Supply
Next, turn off the water supply to the faucet. Most kitchen sinks have shutoff valves located under the sink, with one valve for hot water and one for cold water. Turn each valve clockwise until it stops. Once the valves are closed, turn on the faucet to release any remaining pressure and drain water from the lines. Let the faucet run until no more water comes out.
If the shutoff valves do not close fully, or if water continues running, you may need to turn off the main water supply to the home. This is also a sign that the shutoff valves may need replacement. Older valves can wear out, seize, or leak after being disturbed. Since these valves are important for future repairs and emergencies, it is worth making sure they work properly. At Lance Maxwell Plumbing, we often help homeowners replace outdated shutoff valves during fixture upgrades so the entire setup is safer and easier to maintain.
Step 3: Disconnect the Water Supply Lines
After the water is off, place your bucket under the supply line connections. Use an adjustable wrench to loosen the nuts connecting the supply lines to the shutoff valves. Some water may drip out, which is normal, so keep towels close by. Once the supply lines are disconnected from the valves, you can disconnect them from the faucet if needed. Many homeowners choose to replace old supply lines at the same time as the faucet, especially if the lines are stiff, corroded, kinked, or outdated.
This step may be simple, but it can also be frustrating if the connections are tight or rusted. A basin wrench can be especially helpful because it is designed to reach nuts in tight spaces behind the sink basin. Avoid using excessive force, because damaged fittings can create leaks or require extra repairs. If the connections refuse to budge, it may be time to bring in a professional plumber. Sometimes the smartest DIY move is knowing when to stop before the sink cabinet becomes a splash zone.
Step 4: Remove the Old Faucet
Now it is time to remove the old faucet. Look underneath the sink to find the mounting nuts or brackets holding the faucet in place. Use a basin wrench or adjustable wrench to loosen and remove them. Depending on the age of the faucet, the hardware may be rusty or covered with mineral buildup. Take your time and use steady pressure to avoid damaging the sink or countertop.
Once the mounting hardware is removed, lift the old faucet out from the top of the sink. If it does not come loose easily, there may be old sealant around the base. Use a putty knife carefully to break the seal without scratching the sink surface. After the faucet is removed, clean the area thoroughly. Remove old plumber’s putty, silicone, mineral deposits, grime, and anything else that could prevent the new faucet from sitting flat. A clean surface helps create a better seal and a more professional-looking installation.
Step 5: Prepare the New Faucet
Before installing the new faucet, check that all parts are included. Compare the parts in the box to the manufacturer’s instructions. Make sure you have the mounting hardware, gasket, supply lines, sprayer hose, weight, and any other components required for your model. If your new faucet has a pull-down or pull-out sprayer, review how the hose and weight should be installed. These parts need enough room to move freely under the sink.
You should also confirm that the faucet matches your sink configuration. Some sinks have one hole, while others have three or four. Many modern faucets include a deck plate to cover extra holes, but not all models do. If your sink has extra openings, you may need accessories such as a soap dispenser, side sprayer, or hole cover. Planning this before installation helps avoid an awkward moment where the new faucet looks great, but the sink has an uncovered hole waving hello.
Step 6: Install the New Faucet
Place the new faucet into the mounting hole or holes according to the manufacturer’s instructions. If the faucet includes a gasket, position it properly between the faucet base and sink. Some installations may call for plumber’s putty or silicone sealant, but many modern faucets use a built-in gasket instead. Always follow the instructions for your specific faucet model. Using the wrong sealant or too much sealant can create cleanup issues or affect the fit.
From underneath the sink, secure the faucet with the included mounting nuts or brackets. Tighten the hardware until the faucet is stable, but avoid overtightening. Too much pressure can damage the sink, countertop, or faucet components. Before fully tightening everything, check from above to make sure the faucet is straight and centered. This is one of those small details that matter every time you walk into the kitchen. A crooked faucet may work, but it will quietly bother you forever.
Step 7: Connect the Water Supply Lines
Once the faucet is secured, connect the hot and cold water supply lines. Many faucets include integrated supply lines, while others require separate lines. Be sure to connect the hot line to the hot shutoff valve and the cold line to the cold shutoff valve. The hot water line is usually on the left, and the cold water line is usually on the right, but it is still wise to verify before connecting.
Tighten the connections with an adjustable wrench, but again, do not overtighten. If the manufacturer recommends plumber’s tape for certain threaded connections, apply it as directed. Some supply line fittings are designed to seal without tape, so check the instructions before adding anything. Once everything is connected, make sure the lines are not twisted, kinked, or pressed against sharp edges. Properly positioned supply lines help prevent leaks and premature wear.
Step 8: Test for Leaks
Now you can slowly turn the water supply valves back on. Open them gradually while watching the connections under the sink. Check for drips around the shutoff valves, supply line connections, and faucet base. Turn on the faucet and let both hot and cold water run for a few minutes. If your faucet has a sprayer, test that as well.
While the water is running, keep looking under the sink with a flashlight. Some leaks are obvious, but others may start as tiny droplets that are easy to miss. Wipe each connection with a dry paper towel to check for moisture. If you find a leak, turn the water off and gently tighten the connection. If the leak continues, the fitting may need to be reseated, the supply line may need replacement, or there may be a problem with the valve or faucet component.
Step 9: Flush the Faucet
After installation, remove the aerator from the faucet spout if the manufacturer recommends it. Turn on the water and let it run for a short time to flush out debris, sediment, or particles that may have entered the lines during installation. This is especially important if you disturbed older plumbing connections. Once the water runs clear, turn it off and reinstall the aerator. This simple step helps protect the faucet and maintain proper water flow.
If you notice low water pressure after installation, debris may be trapped in the aerator or supply line. Cleaning the aerator may solve the issue. If pressure remains low, there may be a valve issue, supply line blockage, or another plumbing concern. A professional plumber can help diagnose the problem quickly. At Lance Maxwell Plumbing, we handle faucet installations and plumbing repairs throughout the Jacksonville and Orange Park areas, so we know how to spot issues that may not be obvious at first glance.
When Should You Call a Professional Plumber?
Replacing a kitchen faucet can be a reasonable DIY project, but it is not always the best option for every situation. If your plumbing is older, corroded, leaking, or difficult to access, professional service can save time and help prevent damage. A plumber can also make sure the faucet is properly installed, sealed, and connected to dependable supply lines. This is especially important if you are upgrading to a more advanced faucet, such as a touchless model or one with additional features. Even a small mistake can lead to leaks, cabinet damage, or water waste.
You should consider calling a plumber if:
- The shutoff valves are stuck, leaking, or missing
- You see corrosion on pipes or fittings
- The old faucet cannot be removed safely
- Your new faucet requires changes to the plumbing setup
- You find water damage or mold under the sink
- The faucet leaks after installation
- You are not comfortable working with water supply lines
A professional installation gives you peace of mind. It also gives you the confidence that your new faucet is ready for daily use. Since the kitchen is one of the busiest rooms in the home, dependable plumbing matters. Nobody wants to start dinner prep and discover the sink has decided to create its own indoor water feature.
FAQ
How long does it take to replace a kitchen faucet?
For a straightforward installation, replacing a kitchen faucet may take one to two hours. However, the timeline can be longer if the old faucet is corroded, the shutoff valves are damaged, or the sink area is difficult to access. Professional plumbers can often complete the job efficiently because they have the right tools and experience.
Do I need to replace the supply lines with the faucet?
It is often a good idea to replace old supply lines when installing a new faucet. New supply lines can reduce the risk of leaks and help ensure a secure connection. If your existing lines are worn, kinked, stiff, or corroded, they should be replaced.
Can I install any faucet on my kitchen sink?
Not always. You need to match the faucet to your sink’s hole configuration and available space. Some faucets require one hole, while others need multiple holes or a deck plate. Always check the faucet specifications before buying.
Why is my new faucet leaking at the base?
A leak at the base may be caused by an improper seal, loose mounting hardware, incorrect installation, or a defective component. It may also be water splashing around the base rather than an actual leak. If the problem continues, a plumber can identify the cause and correct it.
What should I do if my shutoff valve will not turn?
Do not force it. A stuck valve can break and cause a larger plumbing issue. If the valve will not turn, call a professional plumber to inspect and replace it if needed.
Is a pull-down faucet better than a standard faucet?
A pull-down faucet can be more convenient for rinsing dishes, cleaning the sink, and filling large pots. However, the best choice depends on your sink, kitchen layout, and personal preferences. High-quality options from brands like Delta, Kohler, and Moen offer reliable performance in many styles.
