Gathering Your Tools and Supplies
Before you start, it’s crucial to have all the necessary tools and supplies ready. This will make the process much smoother and prevent last-minute trips to the hardware store.
Essential Tools You’ll Need
- Adjustable Wrench (or two): These are vital for loosening and tightening various nuts and fittings. Having two can be helpful for holding one part while turning another.
- Basin Wrench: This specialized tool is a lifesaver for reaching nuts in tight spaces behind the sink, which are often hard to access with a regular wrench.
- Plumber’s Putty or Silicone Caulk: This is used to create a watertight seal between the faucet base and the sink or countertop.
- Bucket or Towels: To catch any residual water in the pipes and to protect your cabinets from drips.
- Safety Glasses: Protect your eyes from debris or water splashes.
- Gloves: Keep your hands clean and protect them from any sharp edges.
- Flashlight or Work Light: To illuminate the often-dark area under the sink.
- Screwdriver Set (Phillips and Flathead): You might need these for various components.
- Old Toothbrush or Wire Brush: For cleaning mineral deposits and old plumber’s putty from the sink surface.
- Rags or Paper Towels: For cleaning up spills and drying parts.
Your New Faucet and Faucet Parts
Of course, you’ll need your new kitchen faucet! Make sure it’s compatible with your sink’s hole configuration (usually one, two, three, or four holes). Also, check if your new faucet comes with all the necessary faucet parts, such as supply lines. If not, you’ll need to purchase those separately.
- New Kitchen Faucet: Ensure it matches your sink’s hole count.
- Supply Lines: If your new faucet doesn’t include them, you’ll need new flexible supply lines to connect the faucet to your hot and cold water shut-off valves. Make sure they are the correct length and have the right fittings for your valves.
Step-by-Step Guide to Changing Your Kitchen Faucet
Now that you have everything, let’s get started with the actual installation. We’ll cover each stage of the DIY faucet replacement from start to finish.
Step 1: Turning Off the Water Supply
This is the most critical first step for any plumbing work. You don’t want to be dealing with a sudden gush of water!
- Locate Shut-Off Valves: Look under your kitchen sink. You should see two valves (one for hot water, one for cold) connected to the pipes coming from the wall.
- Turn Off the Valves: Turn the handles clockwise until they are snug. If you have older lever-style valves, turn the lever 90 degrees so it’s perpendicular to the pipe.
- Test the Water: Turn on your old faucet to relieve any remaining water pressure and to confirm that the water is indeed off. Let the water run until it stops.
Step 2: Removing the Old Faucet
This is where you’ll be doing most of your work in the cramped space under the sink. Patience is key!
Faucet Removal Process:
- Clear the Area: Remove everything from the cabinet under your sink. Place your bucket and towels to catch any drips.
- Disconnect Supply Lines: Use your adjustable wrench to loosen the nuts connecting the flexible supply lines to the shut-off valves. Have your bucket ready to catch any residual water.
- Disconnect Sprayer Hose (If Applicable): If your old faucet has a side sprayer, find where its hose connects under the sink and disconnect it. There might be a clip or a threaded nut.
- Loosen Faucet Mounting Nuts: This is where the basin wrench really shines. Look up at the underside of the sink where the faucet body meets the sink. You’ll see large nuts or mounting brackets holding the faucet in place.
- The basin wrench is designed to grip these nuts from the side, allowing you to turn them even when they’re in tight spots.
- Place the basin wrench onto the nut and turn it counter-clockwise to loosen. You might have to reposition the wrench multiple times.
- If you don’t have a basin wrench, try using your adjustable wrench, but be prepared for a tougher time.
- Lift Out the Old Faucet: Once all the mounting nuts and connections are free, you should be able to lift the old faucet straight up and out from the top of the sink.
- Clean the Sink Surface: Use a putty knife or scraper to gently remove any old plumber’s putty or caulk from the sink surface around the faucet holes. A stiff brush or an old toothbrush can help get into corners. This is important for a good seal with your new faucet.
Step 3: Preparing the New Faucet for Installation
Before you put the new faucet in, it’s wise to assemble some of its parts according to the manufacturer’s instructions.
New Faucet Assembly:
- Read the Instructions: Every faucet is slightly different. Always refer to the specific installation manual that came with your new faucet.
- Attach Supply Lines: If your new faucet has integrated supply lines, you might not need to do this. If not, screw the new flexible supply lines into the designated ports on the faucet body. Hand-tighten them first, then give them a snug turn with an adjustable wrench. Be careful not to overtighten.
- Apply Sealant: Most new faucets come with a gasket or require plumber’s putty/silicone caulk to create a seal.
- If it has a gasket, ensure it’s seated correctly on the base of the faucet.
- If using plumber’s putty, roll a rope of putty and press it firmly around the underside of the faucet base or escutcheon plate.
- If using silicone caulk, apply a thin, continuous bead around the underside of the faucet base.
Step 4: Installing the New Faucet
This is where your new kitchen tap starts to take shape!
Installing the New Sink Faucet:
- Position the New Faucet: Carefully lower the new faucet through the holes in your sink or countertop. Make sure it’s oriented correctly.
- Secure the Faucet: From underneath the sink, thread the mounting nuts or brackets onto the faucet shanks. Hand-tighten them first.
- Align the Faucet: Go back to the top of the sink and make sure the faucet is straight and centered. Once you’re happy with the alignment, tighten the mounting nuts securely from underneath. Again, use your basin wrench or adjustable wrench. Don’t overtighten, as you could damage the sink or countertop.
- Connect Supply Lines to Shut-Off Valves: Connect the other end of the flexible supply lines to the corresponding hot and cold water shut-off valves.
- Hand-tighten the nuts onto the valves.
- Use your adjustable wrench to tighten them a quarter to half turn past hand-tight. Avoid overtightening.
Step 5: Connecting the Sprayer (If Applicable)
If your new faucet has a pull-out or side sprayer, now is the time to connect its hose.
- Route the Hose: Feed the sprayer hose through its designated opening in the faucet body.
- Connect Hose to Faucet Body: Under the sink, you’ll find the connection point for the sprayer hose. It usually just snaps into place or screws on. Refer to your faucet’s manual for specifics.
- Attach Counterweight: Most pull-out sprayers have a hose counterweight that needs to be attached to the hose. This helps retract the spray head. Position the weight according to the manufacturer’s instructions.
Step 6: Turning the Water Back On and Testing
This is the moment of truth! Let’s see if your new installation is leak-free.
- Slowly Turn On Water Valves: Gently turn the hot and cold water shut-off valves counter-clockwise to open them.
- Check for Leaks: Carefully inspect all the connections you made – at the faucet shanks and at the shut-off valves – for any signs of dripping. Use your flashlight.
- Turn on the Faucet: Turn on the new faucet to a medium setting. Let the water run for a minute or two to flush out any air or debris from the lines.
- Test Hot and Cold: Check that both hot and cold water are flowing correctly.
- Operate Sprayer: If you have a sprayer, test its function and check for leaks at its connection point.
- Final Leak Check: After running the water, turn off the faucet and do one last, thorough check for leaks under the sink. Tighten any connections slightly if you find even a small drip.
Step 7: Finishing Touches
Once you’re confident there are no leaks, you can tidy up.
- Wipe Down: Wipe away any excess plumber’s putty or caulk from the sink surface.
- Replace Items: Put all your cleaning supplies and items back under the sink.
Common Issues and Troubleshooting
Even with careful work, you might encounter a few snags. Here are some common issues and how to fix them.
Table: Troubleshooting Common Faucet Problems
| Problem | Possible Cause | Solution |
|---|---|---|
| Leaky Faucet Base | Insufficient or damaged seal at the base | Tighten mounting nuts slightly. If still leaking, remove faucet, reapply plumber’s putty or caulk, and reinstall. |
| Dripping from Spout | Internal cartridge or washer issue (in older faucets) | If your new faucet drips, check that all connections are snug. If it persists, it could be a faulty cartridge and you may need to contact the manufacturer for replacement parts. |
| Low Water Pressure | Clogged aerator or debris in supply lines | Unscrew the aerator at the tip of the spout and clean it. If the issue persists, shut off the water, disconnect supply lines, and flush them briefly into a bucket. |
| Water Leaking from Connections | Loose fittings or damaged washers/O-rings | Tighten the connection slightly. If it continues, shut off the water, disconnect, and check for damaged washers or O-rings. Replace if necessary. |
| Sprayer Not Working Correctly | Kinked hose, loose connection, or debris | Check for kinks in the hose. Ensure the hose is securely connected. Clean any debris from the sprayer head or its internal parts. |
Leaky Faucet Repair: A Temporary Fix vs. Replacement
While this guide focuses on replacing your entire kitchen tap, sometimes a minor leak can be temporarily fixed. If you have a small drip from the spout that isn’t causing major damage, you might be able to identify the faulty faucet parts, like washers or O-rings, and replace them. However, if the faucet is old, corroded, or the leak is significant, a full replacement is often the best long-term solution for your kitchen plumbing.
Frequently Asked Questions (FAQ)
Q: How long does it typically take to change a kitchen faucet?
A: For an experienced DIYer, it can take as little as an hour. For a first-timer, it might take 2-4 hours, depending on how easily the old faucet comes off and how familiar you are with plumbing connections.
Q: Do I need to shut off the main water supply to my house?
A: No, usually you only need to shut off the hot and cold water supply valves located directly under your sink.
Q: What is plumber’s putty, and when do I use it?
A: Plumber’s putty is a moldable sealing compound used to create a watertight seal between plumbing fixtures and a surface, like a faucet base and a sink. You use it around the base of the faucet before installing it to prevent water from seeping underneath.
Q: Can I use silicone caulk instead of plumber’s putty?
A: Yes, in many cases, silicone caulk can be used as an alternative to plumber’s putty. Some manufacturers even recommend it. Always check your faucet’s installation guide.
Q: My new faucet came with a plastic mounting nut. Is that okay?
A: Yes, many modern faucets use durable plastic mounting hardware. As long as it’s designed for the faucet, it should be strong enough. Just be careful not to overtighten it, as plastic can strip or crack.
Q: What if the holes in my sink don’t match my new faucet?
A: You’ll need to ensure your new faucet is compatible with your sink’s hole configuration. If the holes don’t match, you might need to buy an adapter plate to cover extra holes or consider a different faucet.
Q: I can’t get the old faucet nuts off. What should I do?
A: This is a common problem, especially with older fixtures. A penetrating lubricant (like WD-40) applied to the nuts can help. Let it sit for a while. A basin wrench is also essential for leverage. If they are severely corroded, you might need to use a hacksaw to cut them off, but be very careful not to damage the sink.
