Meta Description: Leaky faucet? Learn how to easily tighten that pesky faucet nut under your sink with our simple, step-by-step guide. Save money and avoid costly plumber calls! We cover common tools and troubleshooting tips.

A leaky faucet can be incredibly annoying, and often, the culprit is a loose faucet nut under the sink. Fortunately, tightening this nut is a relatively simple DIY fix that can save you time and money on a plumber's visit. This guide will walk you through the process, providing clear instructions and helpful tips.

Tools You'll Need:

Before you begin, gather the following tools:

Adjustable wrench: This is the most important tool. Choose one that's large enough to comfortably grip the faucet nut.
Basin wrench: This specialized tool is highly recommended, especially for hard-to-reach nuts. It allows for better leverage and maneuverability in tight spaces.
Flashlight: The area under the sink is often dark, so a flashlight is crucial for clear visibility.
Gloves (optional): Protecting your hands from grime and potential cuts is always a good idea.
Towels or rags: Use these to absorb any drips or spills.

Step-by-Step Instructions:

Turn off the water supply: Locate the shut-off valves for the hot and cold water lines supplying your faucet. Turn both valves clockwise to completely shut off the water flow.
Prepare the area: Clear the space under the sink. Remove any obstructions that might hinder your access to the faucet. Lay down towels to protect the sink and floor from potential water damage.
Locate the faucet nut: The faucet nut is usually located where the faucet body connects to the sink. It might be difficult to reach, depending on the sink's configuration.
Use the appropriate wrench: If you can access the nut easily, use an adjustable wrench. If the nut is hard to reach, a basin wrench is essential. Position the wrench firmly on the nut.
Tighten the nut: Turn the wrench clockwise to tighten the nut. Apply firm, steady pressure. Avoid using excessive force, as you could damage the faucet or the sink. Tighten it gradually, checking for leaks periodically.
Test for leaks: Turn the water supply back on and carefully check for any leaks around the faucet connection. If the leak persists, you might need to try tightening the nut further or consider other potential problems.

Troubleshooting Tips:

Nut won't budge: If the nut is extremely stubborn, try using penetrating oil to loosen it. Apply the oil to the nut and let it sit for a few minutes before attempting to tighten it again. A stronger wrench might also be necessary.
Stripped nut: If the nut is stripped, you'll likely need to replace it. This might require disassembling the faucet partially, which is best left to a professional plumber if you're not comfortable doing it yourself.
Persistent leak: If tightening the nut doesn't stop the leak, the problem might be elsewhere in the faucet. Check for worn-out O-rings or other damaged parts. Consider calling a plumber if you are unable to resolve the issue.

Preventing Future Problems:

Regularly check your faucet connections for tightness. This simple preventative measure can help avoid future leaks and save you from having to perform this repair again soon.

By following these steps, you can successfully tighten a loose faucet nut and fix a leaky faucet—a satisfying DIY accomplishment! Remember, if you're uncomfortable performing this repair yourself, it's always best to call a qualified plumber.
