Hey there! I'm a supplier of kitchen basin sinks, and I've seen a lot of folks scratching their heads over how to install a faucet on their kitchen sink. It might seem like a daunting task, but trust me, with the right steps and a bit of patience, you can get it done in no time. In this blog, I'll walk you through the whole process, step by step.
What You'll Need
Before we start, let's gather all the tools and materials you'll need for this project. You'll need a new faucet, of course. If you're looking for a great sink to pair with your new faucet, check out our Single Bowl Undermount Kitchen Sink, Single Bowl Workstation Sink, or Nano Pvd Black Sink.
Apart from the sink and faucet, you'll also need a set of wrenches (both adjustable and basin wrenches are good to have), a screwdriver, plumber's putty or silicone caulk, Teflon tape, a bucket, and a rag.
Step 1: Turn Off the Water Supply
This is a crucial first step. You don't want water gushing out everywhere when you start working on the faucet. Locate the shut-off valves under the sink. There should be two valves, one for hot water and one for cold water. Turn them clockwise until they're fully closed. You can also turn off the main water supply to your house if you're not sure which valves are for the kitchen sink.
Once you've turned off the water, open the faucet handles to relieve any pressure in the pipes. Let the water drain into a bucket.
Step 2: Remove the Old Faucet
If you're replacing an old faucet, you'll need to remove it first. Start by disconnecting the water supply lines from the faucet. Use an adjustable wrench to loosen the nuts that connect the lines to the faucet. Be careful not to damage the lines.
Next, remove the mounting nuts that hold the faucet in place. These nuts are usually located under the sink. You might need a basin wrench to reach them. Once the nuts are loose, you can lift the old faucet out of the sink.
Step 3: Clean the Sink
Before installing the new faucet, it's a good idea to clean the area where the old faucet was. Use a rag to wipe away any dirt, grime, or old putty. This will ensure a good seal for the new faucet.
Step 4: Prepare the New Faucet
Take a look at your new faucet and familiarize yourself with its components. Some faucets come with pre-attached hoses, while others require you to attach them yourself. If you need to attach the hoses, use Teflon tape to wrap the threads of the connections. This will help prevent leaks.
Step 5: Apply Putty or Caulk
Apply a thin layer of plumber's putty or silicone caulk around the base of the new faucet. This will create a watertight seal between the faucet and the sink. Make sure the putty or caulk is evenly distributed.
Step 6: Install the New Faucet
Carefully place the new faucet into the holes in the sink. Align the holes in the faucet with the holes in the sink. From under the sink, insert the mounting nuts onto the faucet stems and tighten them using a basin wrench. Make sure the faucet is secure and doesn't wobble.
Step 7: Connect the Water Supply Lines
Connect the hot and cold water supply lines to the corresponding inlets on the faucet. Use an adjustable wrench to tighten the nuts, but be careful not to overtighten them. Overtightening can damage the connections and cause leaks.
Step 8: Turn On the Water Supply
Once the water supply lines are connected, it's time to turn on the water. Slowly open the shut-off valves under the sink. Check for any leaks around the connections. If you see any leaks, tighten the nuts a little more.

Step 9: Test the Faucet
Turn on the faucet handles and let the water run for a few minutes. Check for any leaks from the faucet itself or from the connections under the sink. If everything looks good, you're all set!
Troubleshooting Tips
- Leaking connections: If you notice a leak around a connection, try tightening the nut a little more. If that doesn't work, you might need to add more Teflon tape or replace the washer.
- Low water pressure: If the water pressure is low, check the shut-off valves to make sure they're fully open. You might also need to clean the aerator on the faucet spout.
- Faucet not working properly: If the faucet isn't working as it should, make sure all the connections are secure and the water supply is turned on. If the problem persists, you might need to consult the manufacturer's instructions or call a professional plumber.
