Preparing for Your Two Handle Kitchen Faucet Installation
Before you begin replacing a two handle faucet, it’s essential to gather all the necessary faucet installation tools and materials. Having everything ready will make the installation process smoother and more efficient.
Essential Tools and Materials
Here’s a list of what you’ll need:
- New Two-Handle Kitchen Faucet: Ensure it’s compatible with your sink’s hole configuration.
- Adjustable Wrenches (2): For loosening and tightening various fittings.
- Basin Wrench: A specialized tool designed to reach nuts in tight spaces under the sink. This is crucial for under sink plumbing.
- Plumber’s Putty: Used for creating a watertight seal around the faucet base.
- Pipe Thread Tape (Teflon Tape): For sealing threaded connections.
- Bucket: To catch any residual water.
- Rags or Towels: For cleaning up spills.
- Safety Glasses: To protect your eyes from debris.
- Flashlight or Work Light: For better visibility under the sink.
- Screwdriver Set (Phillips and Flathead): For removing any existing parts or components.
- Old Toothbrush or Stiff Brush: For cleaning debris from the sink surface.
- Optional: Pliers: Can be helpful for gripping or turning certain parts.
Shutting Off the Water Supply
The first and most critical step in any faucet installation is to shut off the water supply.
- Locate Shut-Off Valves: Look for the two shut-off valves under your sink. These are usually connected to the hot and cold water pipes coming from the wall.
- Turn Off Valves: Turn both valves clockwise until they are fully closed. If your valves are old or don’t seem to be working correctly, you may need to shut off the main water supply to your house.
- Drain Remaining Water: Turn on the old faucet handles to release any water pressure left in the lines. Let the water drain completely into the sink.
Removing Your Old Kitchen Faucet
Once the water is off, you can begin removing the old faucet. This part of replacing a two handle faucet can sometimes be the most challenging due to confined spaces.
Disconnecting Water Supply Lines
- Place Bucket: Position your bucket directly under the under sink plumbing connections to catch any drips.
- Disconnect Lines: Using an adjustable wrench, carefully loosen the nuts connecting the existing water supply lines to the shut-off valves. You might need another wrench to hold the valve steady while you turn the nut.
- Remove Faucet Connections: Under the sink, locate where the old faucet’s supply lines connect to the faucet itself. Use your adjustable wrench or basin wrench to loosen and disconnect these. Be prepared for a small amount of water to come out.
Detaching the Faucet Body
The mounting faucet body is secured to the sink from underneath.
- Locate Mounting Nuts: Peer under the sink and find the nuts or screws that hold the old faucet in place. These are typically large plastic or metal nuts.
- Use Basin Wrench: The basin wrench is your best friend here. Its long handle and swiveling jaw are designed to reach and turn these nuts in tight spaces.
- Loosen and Remove Nuts: Carefully loosen these nuts using the basin wrench. Once loosened, you should be able to unscrew them by hand.
- Lift Out Old Faucet: With the water lines and mounting nuts removed, you should be able to lift the old faucet straight up and out of the sink holes.
Cleaning the Sink Surface
Before installing the new faucet, clean the sink surface where the old one was mounted.
- Remove Old Sealant: Scrape away any old plumber’s putty or sealant residue from the sink. An old toothbrush or a plastic scraper can be helpful here.
- Wipe Clean: Wipe the area with a damp cloth to ensure it’s clean and dry. This provides a good surface for the new faucet’s seal.
Installing Your New Two-Handle Kitchen Faucet
Now for the exciting part – installing your new faucet! This is where we focus on connecting water supply lines and sealing faucet base.
Preparing the New Faucet
- Check Components: Unpack your new faucet and ensure all parts are present according to the manufacturer’s instructions.
- Install Deck Plate (If Applicable): If your sink has more holes than your new faucet needs, you’ll likely use a deck plate. Slide this over the faucet base before proceeding.
- Apply Plumber’s Putty: Roll a rope of plumber’s putty about ¼ inch thick. Place this around the underside of the faucet base or the deck plate, creating a seal that will prevent water from seeping under the faucet. For some modern faucets, a rubber gasket is provided, and plumber’s putty may not be necessary. Always check your faucet’s specific instructions.
Mounting the Faucet Body
This is the core of faucet installation tools usage for the mounting faucet body.
- Position the Faucet: Carefully feed the faucet’s shanks (the threaded posts that go through the sink) through the corresponding holes in the sink. Ensure the faucet is oriented correctly.
- Secure with Washers and Nuts: From underneath the sink, slide the rubber or plastic washers (if provided) onto the faucet shanks. Then, thread on the mounting nuts.
- Tighten Faucet Nuts: Hand-tighten the nuts first. Then, use your basin wrench or adjustable wrench to further tighten them. Ensure the faucet remains straight and centered as you tighten. You want them snug, but don’t overtighten, as this can damage the sink or faucet. For metal sinks, be particularly careful not to strip the threads. Tightening faucet nuts correctly is vital for stability.
Connecting Water Supply Lines
This is the crucial step for connecting water supply lines.
- Connect to Shut-Off Valves: Take your new flexible water supply lines. Wrap the threads of the shut-off valve outlets with pipe thread tape (Teflon tape) a few times clockwise. Then, connect one end of the hot water supply line to the hot shut-off valve and the cold water supply line to the cold shut-off valve. Hand-tighten the nuts, then use an adjustable wrench to tighten them another quarter to half turn.
- Connect to Faucet: Connect the other ends of the supply lines to the corresponding hot and cold inlets on the new faucet shanks. Again, hand-tighten first, then use an adjustable wrench to snug them up. Ensure the lines are not twisted or kinked.
Table 1: Connecting Supply Lines
| Component | Action | Tool Required |
|---|---|---|
| Shut-off Valve | Wrap threads with pipe thread tape | None (hands) |
| Shut-off Valve | Connect supply line nut | Adjustable Wrench |
| Faucet Shank | Connect supply line nut | Adjustable Wrench |
Installing the Handles
If your faucet has separate handles, this is the next step in replacing a two handle faucet.
- Slide Handles onto Shanks: Slide the hot and cold handles onto their respective shanks. Pay attention to any markings indicating hot (usually red) and cold (usually blue) or the shape of the handle base to ensure proper alignment.
- Secure Handles: Most handles have a small set screw on the underside or back. Use a small Allen wrench or screwdriver to tighten these set screws, securing the handles in place.
Installing the Sprayer (If Applicable)
If your faucet includes a side sprayer, follow these steps:
- Connect Sprayer Hose: Locate the sprayer hose outlet on the faucet body. Connect the sprayer hose to this outlet. Some systems use a quick-connect fitting, while others screw on.
- Mount Sprayer Holder: If your faucet has a separate holder for the sprayer, mount it to the sink or countertop according to the manufacturer’s instructions, often using a screw from underneath.
Final Steps and Leak Testing
You’re almost done! These final checks ensure your installation is successful.
Turning the Water Back On
- Check Connections: Double-check that all nuts and connections are snug.
- Open Shut-Off Valves: Slowly turn both shut-off valves counter-clockwise to restore water flow.
- Inspect for Leaks: Immediately check all connections under the sink and around the faucet for any signs of water.
Leak Testing Faucet
This is a critical part of leak testing faucet performance.
- Run Water: Turn on the new faucet. Let the water run for a minute or two, checking both hot and cold.
- Operate Handles and Sprayer: Turn the handles on and off, test the sprayer (if applicable), and check for proper water flow and any unusual noises.
- Re-check Under Sink: Get under the sink again and thoroughly inspect all connections for any drips or leaks. Pay close attention to where the supply lines connect to both the shut-off valves and the faucet. Also, check around the base of the faucet on the sink deck.
- Tighten if Necessary: If you find a small drip, try tightening faucet nuts or fittings slightly, usually no more than a quarter turn.
Cleaning Up
- Remove Excess Putty: If any plumber’s putty squeezed out around the base of the faucet, wipe it away with a damp cloth.
- Dry Everything: Dry off any water drips from the faucet and the sink area.
- Organize Tools: Put away your faucet installation tools.
Troubleshooting Common Issues
Even with careful work, you might encounter minor problems.
Drips from Handle
- Cause: Loose packing nut behind the handle or worn O-ring.
- Solution: Try tightening the packing nut slightly (usually accessible after removing the handle cap). If that doesn’t work, you may need to replace the O-ring inside the handle assembly.
Leaks at Supply Line Connections
- Cause: Loose connection or faulty washer/seal.
- Solution: Ensure the nuts are properly tightened. If a leak persists, you may need to disconnect the line, check the washer, and re-tape the threads on the valve before reconnecting.
Low Water Pressure
- Cause: Debris in the aerator or blocked supply lines.
- Solution: Unscrew the aerator at the tip of the faucet spout. Clean any debris from it, then screw it back on. If the problem persists, check the supply lines for kinks or potential blockages.
Faucet Wobbles
- Cause: Mounting nuts are not tight enough.
- Solution: Go back under the sink and tighten the mounting faucet body nuts until the faucet is secure.
When to Call a Professional
While replacing a two handle faucet is a manageable DIY task, there are times when professional help is advisable:
- Corroded or Stuck Parts: If your old faucet or shut-off valves are severely corroded and won’t budge, forcing them could cause pipe damage.
- Leaky Shut-Off Valves: If your shut-off valves themselves are leaking or won’t close properly, it’s best to have a plumber replace them before proceeding.
- Uncertainty: If at any point you feel unsure or uncomfortable with a step, don’t hesitate to call a qualified plumber. A small mistake can lead to significant water damage.
Frequently Asked Questions (FAQ)
Q1: How long does it typically take to install a two-handle kitchen faucet?
A1: For a DIYer, the process usually takes between 1 to 3 hours. This includes preparation, removal of the old faucet, installation of the new one, and cleanup.
Q2: What is the difference between plumber’s putty and silicone caulk for faucet installation?
A2: Plumber’s putty is a soft, pliable compound used to create a watertight seal between plumbing fixtures (like faucets) and surfaces (like sinks). It remains somewhat soft and is ideal for seals where there isn’t much movement. Silicone caulk, on the other hand, cures to a flexible, waterproof seal and is often used for sealing around the edge of a deck plate or for sealing the backsplash to the countertop. For most faucet bases, plumber’s putty or a provided rubber gasket is the standard.
Q3: Do I need to turn off the main water supply?
A3: You only need to turn off the main water supply if your under-sink shut-off valves are faulty, corroded, or if you don’t have individual shut-off valves for your kitchen faucet.
Q4: What are “flexible water supply lines”?
A4: These are the hoses that connect your faucet’s inlets to the hot and cold water shut-off valves. They are typically made of braided stainless steel or reinforced rubber for durability and flexibility, making them easier to route in tight under sink plumbing spaces.
Q5: How tight should I make the faucet nuts?
A5: You should tighten the faucet nuts enough to secure the faucet firmly without wobbling. Hand-tighten them first, then use a wrench to snug them up. Overtightening can damage the faucet, the sink, or the threads. A good rule of thumb is a quarter to half turn past hand-tight, but it’s better to check the manufacturer’s instructions for your specific faucet.
Q6: Can I reuse my old supply lines?
A6: It’s generally not recommended. Old supply lines can become brittle, kinked, or develop internal wear, leading to leaks. It’s best to replace them with new ones when installing a new faucet.
By following these steps, you can confidently tackle your kitchen faucet replacement and enjoy your updated kitchen sink with a brand-new, functional two-handle faucet.
