A loose kitchen faucet can be annoying and frustrating. It can cause water leaks, damage your sink, and make your faucet wobble and squeak.

Don’t worry, we have got you covered. In this blog post, we will show you how to tighten kitchen faucet nut under sink in six easy steps. You will need some basic tools and a little bit of patience, but you will be able to do it yourself without calling a plumber.

What You Will Need to Tighten Kitchen Faucet Nut Under Sink

Before you start, make sure you have the following tools and materials ready:

  • A basin wrench: This is a long and slender tool with adjustable jaws at one end. It is designed to reach and tighten nuts in tight spaces under the sink.
  • A flashlight or a headlamp: You will need some light to see what you are doing under the sink.
  • A towel or a bucket: You will need something to catch any water that may drip from the faucet or the pipes.
  • Safety glasses: You will need to protect your eyes from any dust or debris that may fall from under the sink.

Step 1: Turn Off the Water Supply

The first thing you need to do is turn off the water supply to the faucet. You can do this by locating the shut-off valves under the sink and turning them clockwise until they stop. If you can’t find them, you may need to turn off the main water supply for your house.

Step 2: Clear Out the Space Under the Sink

Next, you need to clear out any items or obstacles that may be under the sink. You will need enough room to lie down and reach up to the faucet nut. You may also want to put a towel or a bucket under the faucet to catch any water that may drip from the pipes.

Step 3: Adjust the Position of the Faucet

Now, you need to adjust the position of the faucet on top of the sink. You want it to be aligned with the holes and centered on the sink. You may need someone to help you hold it in place while you work under the sink.

Step 4: Locate and Loosen the Nut

Next, you need to locate the nut that holds the faucet in place under the sink. It is usually a large metal or plastic ring that is attached to a long bolt that goes through the faucet base. You may also see some washers or rubber gaskets around it.

To loosen the nut, you need to use your basin wrench. Adjust the jaws of the wrench so that they fit around the nut. Then, position yourself under the sink so that you can see and reach the nut. Use your flashlight or headlamp if needed.

To use the basin wrench, you need to hook its jaws around the nut and turn its handle counterclockwise. You may need to apply some force and wiggle it a bit until it loosens. Be careful not to damage or scratch the nut or the faucet.

Step 5: Tighten Kitchen Faucet Nut Under Sink

Once you have loosened the nut, you can tighten kitchen faucet nut under sink by turning it clockwise with your basin wrench. You want it to be snug but not too tight. You don’t want to over-tighten it and damage or crack it.

To check if it is tight enough, go back to the top of the sink and see if the faucet is stable and secure. If it still wobbles or moves, go back under the sink and tighten it some more until it stops.

Step 6: Turn On the Water Supply and Test

The last step is to turn on the water supply and test your faucet. Turn on both hot and cold water valves under the sink by turning them counterclockwise until they are fully open. Then, turn on your faucet and check for any leaks or drips.

If everything looks good, congratulations! You have successfully tightened kitchen faucet nut under sink. If you notice any leaks or problems, you may need to repeat some of the steps or call a professional plumber for help.


Tightening kitchen faucet nut under sink is not a difficult task if you have the right tools and follow these simple steps. It can save you money and hassle from calling a plumber or replacing your faucet.
