Your New Faucet Kit
Most new faucet kits come with everything you need, but it’s good to check:
- The new faucet assembly
- Mounting hardware (washers, nuts)
- Supply lines (sometimes included, sometimes sold separately)
- Sprayer hose and weight
- Deck plate (if you’re covering extra holes)
Step-by-Step Guide to Your DIY Faucet Install
Let’s break down the process into manageable steps for your DIY faucet install.
Step 1: Turn Off the Water Supply
This is the most crucial first step.
- Locate the Shut-Off Valves: Look under your sink for two valves. One is for hot water, and the other is for cold water. They usually have small handles.
- Turn Off the Valves: Turn the handles clockwise until they are snug. Don’t overtighten.
- Test the Water: Turn on the old faucet to release any remaining water pressure and to confirm that the water is indeed off. Let it run until no more water comes out.
Step 2: Remove the Old Faucet
Now it’s time to say goodbye to your old kitchen faucet.
Removing the Faucet Body
- Disconnect Supply Lines: Use your adjustable wrench to loosen the nuts connecting the hot and cold water supply lines to the shut-off valves. Have your bucket ready for any drips.
- Disconnect Sprayer Hose (if applicable): If your old faucet has a sprayer, locate where the sprayer hose connects to the faucet body under the sink and disconnect it.
- Loosen Mounting Nuts: This is where your basin wrench or adjustable wrench will come in handy. Reach under the sink and find the nuts that secure the faucet to the sink or countertop. These can be tricky to reach, but a basin wrench is designed for this. Unscrew them completely.
- Lift Out the Old Faucet: Once the nuts and supply lines are disconnected, you should be able to lift the old faucet straight up and out from the top of the sink.
Clearing the Area
- Clean the Sink Surface: Use a putty knife or utility knife to scrape away any old plumber’s putty, caulk, or mineral deposits from the sink or countertop where the old faucet was mounted. Clean the area thoroughly with a rag. This ensures a good seal for your new faucet.
Step 3: Prepare the New Faucet for Installation
Before mounting faucet, let’s get your new one ready.
- Read the Manufacturer’s Instructions: Every faucet is a little different. Always refer to the specific instructions that came with your new faucet.
- Apply Plumber’s Putty: If your faucet doesn’t come with a rubber gasket for the base, you’ll need to use plumber’s putty. Roll a rope of putty about ½ inch thick and place it around the underside of the faucet base or deck plate. This creates a watertight seal. If your faucet came with a gasket, it will serve the same purpose, and you likely won’t need putty.
- Position the Deck Plate (if needed): If your new faucet has a wider base or you’re covering extra holes in your sink, place the deck plate over the holes. Apply plumber’s putty or the included gasket to the underside of the deck plate.
Step 4: Install the New Faucet
This is where your new faucet starts to take shape.
Mounting the Faucet
- Place the Faucet: Carefully insert the faucet through the hole(s) in the sink or countertop. Make sure it’s centered and facing the correct direction. If you’re using a deck plate, place the faucet through the deck plate first.
- Secure from Below: Reach under the sink. Slide any included washers onto the faucet shanks. Then, thread on the mounting nuts provided with your faucet. Hand-tighten them initially.
- Align and Tighten: From the top of the sink, adjust the faucet to its desired position. Then, from underneath, use your basin wrench or adjustable wrench to tighten the mounting nuts. Tighten them securely, but be careful not to overtighten, which could damage the sink or countertop. Ensure the faucet is stable and doesn’t wobble.
Attaching the Faucet Base (if applicable)
Some faucets have separate pieces for the base or handles that attach after the main body is mounted. Follow your manufacturer’s instructions to secure these components. Ensure they are snug and properly aligned.
Step 5: Connect the Sprayer and Water Lines
This is where we bring the water to your new faucet.
Faucet Sprayer Hookup
- Connect the Sprayer Hose: Locate the connection point for the sprayer hose under the sink. This is usually a threaded fitting on the faucet body. Screw the sprayer hose onto this fitting until it’s hand-tight. Then, give it a small tighten with a wrench if needed, but don’t overtighten.
- Attach the Sprayer Weight: Most pull-out or pull-down sprayers have a small weight that clips onto the hose. This weight helps the sprayer head retract smoothly. Slide it onto the hose at the point indicated by the manufacturer’s instructions and secure it.
Connecting Water Lines
- Connect Hot and Cold Supply Lines: Your new faucet will have hot and cold water inlets, usually marked with red and blue indicators. Connect the corresponding hot and cold water supply lines to these inlets. If your new faucet came with integrated supply lines, you’ll be connecting these directly to your shut-off valves.
- Seal Threads (if needed): If you are using separate supply lines and your shut-off valves or faucet inlets have threaded connections that aren’t pre-sealed, wrap Teflon tape clockwise around the threads a few times. This helps prevent leaks.
- Tighten Supply Line Nuts: Use your adjustable wrench to tighten the nuts connecting the supply lines to the faucet inlets and the shut-off valves. Tighten them until snug, then give them an additional quarter to half turn. Again, avoid overtightening.
Step 6: Turn On the Water and Check for Leaks
The moment of truth!
- Slowly Turn On Water: Go back to the shut-off valves under the sink. Turn the handles counter-clockwise slowly to allow water to flow back into the faucet.
- Inspect All Connections: While the water is flowing, carefully inspect all the connections you made: where the supply lines meet the faucet, where they meet the shut-off valves, and where the sprayer hose connects. Look and feel for any drips or leaks.
- Check the Sprayer: Press the trigger on the sprayer to ensure it’s working and check its hose connection for leaks.
- Address Leaks: If you find any leaks, turn off the water supply again and tighten the connection slightly. If a leak persists, you may need to disconnect the line, reapply Teflon tape, and reconnect.
Step 7: Test the Faucet Operation
Now that the water is on and leak-free, let’s test everything.
- Run Both Hot and Cold Water: Turn on the faucet to a medium flow. Check that you have both hot and cold water.
- Test the Sprayer: Engage the sprayer and check its function. Make sure the diverter (the mechanism that switches between the main faucet and the sprayer) is working correctly.
- Check for Smooth Operation: Ensure the single handle moves smoothly from off to hot, cold, and mixed positions.
Step 8: Final Touches and Cleanup
You’re almost done!
- Remove Excess Plumber’s Putty: Wipe away any excess plumber’s putty that squeezed out from under the faucet base or deck plate.
- Clean Up: Wipe down the faucet and the surrounding sink area. Remove the newspaper or drop cloth and clean up any tools or debris.
- Enjoy Your New Faucet! You’ve successfully completed your kitchen faucet replacement.
Troubleshooting Common Issues
Even with careful work, you might run into minor hiccups.
Table: Common Faucet Installation Problems and Solutions
| Problem | Possible Cause | Solution |
|---|---|---|
| Dripping from faucet | Valve not fully closed; Debris in the valve seat; Loose connection. | Ensure shut-off valves are fully closed. Clean debris from valve seat (may require disassembling the old faucet if it’s not leaking from the connections). Tighten connections. |
| Leaking connections | Loose nuts; Worn-out seals; Insufficient or excessive Teflon tape. | Tighten nuts incrementally. Replace supply line washers if damaged. Reapply Teflon tape properly to threaded connections. |
| Low water pressure | Aerator is clogged; Shut-off valves not fully open; Kinked supply line. | Unscrew and clean the aerator. Ensure shut-off valves are fully open. Check supply lines for kinks and straighten them. |
