In this article, I’ll discuss the reason for the loosening of the kitchen faucet, step by step, on how to tighten kitchen faucets.

What Causes a Faucet Nut can be Loose?

It is not a surprise when your kitchen faucet nut keeps on loosening no matter how much you tighten it.

Whether the nut is new or old, they tend to damage as time goes by, resulting in frequent leakages.

This is a sign that your faucet nut has become loose. Some of the reasons that cause a faucet nut to loosen includes;

1. The Faucet Base has become Loose

Frequent use of faucet handles could make it lose and, as a result, starts leaking. When the faucet base becomes loose, the kitchen tap starts wobbling and leaks.

Moreover, a loose faucet base can cause water lines to rapture hence wasting some water that could have otherwise been used for other kitchen tasks.

2. The Screws are Loose

Usually, the head and faucet base beneath the kitchen sink are held together by a bolt.

If the nut holding the bolt becomes loose, the entire sink starts wobbling, and water may start leaking in the process.

3. Worn out ‘O’ Rings

The O rings located at the faucet base helps to secure faucet handles in the correct position. Continued use can make the ring wear out, causing the tap to leak.

4. Damaged Nut Threads

Tightening a loose nut over and over again can be very annoying and, at the same time, a waste.

Frequent tightening of the nut that holds the faucet base and head together can damage its threads.

This can be difficult to tighten, leaving you with no choice but to leave it loose making it start leaking.

5. Over-tightening of the Nut

Some plumbers tend to over-tighten the nut holding faucet base and head together to prevent it from wobbling in the future.

However, some nuts are made of plastic, while others are metallic.

Over-tightening a plastic nut can crack in the process; hence it is not going to hold the faucet firmly.

On the other hand, over-tightening a metallic nut may become hard to remove in the future, or it can even damage the threads making them loose.

How to Tighten Kitchen Faucet Nut Under Sink

A kitchen sink comes along with all the necessary fixtures to make it a complete sink. Even though some entities do not provide instructions on how to tighten the kitchen faucet nut under the sink, the process is straightforward as it does not require a lot of skills other than basic skills.

Whether you want to tighten a nut under a new sink fixture or fit an old one, the process can be tiresome sometimes as you have to bend in order to reach out to the loose nut under the sink.

Some nuts are made of plastic, while others are made of metal, depending on the type of sink.

Either way, care should be taken to ensure the nut remains in good condition both now and in the future.

Below is a step by step process on how to tighten kitchen faucet nut under the sink;

Requirements

If you are planning to tighten a loose kitchen faucet at home, you need to gather all the necessary tools to get the job done.

Most tools needed are the day-to-day tools you usually use at home; hence no need to panic about the requirements expenses.

And if you don’t have all the necessary tools, they can be easily acquired at the workshop near you. The requirements include;

A basin wrench

Adjustable pliers

A flashlight

Step 1: Clear the Space under your Sink.

In order to deliver the best work done, you first of all have to clear out the area beneath your sink. This gives you a humble time while fixing the problem.

Keep yourself away from distractions like cleaning items, garbage bags, and any other thing that might hinder you from doing your task well.

If the sink model has a P-trap, remove it by using the adjustable pliers to loosen the nut holding it together.

Be sure to remove everything that may prevent you from getting the job done at ease and adjust the faucet in position.

Also, be careful with chemicals. Keep them away from being reached by the children or pets around the house.

Step 2: Adjust the Faucet in Place

Put the faucet in place and use the nut to fix them into the appropriate hole in the sink. The faucet should be in line with the wall behind it. This does need necessary skills as it is direct and easy to locate the appropriate position of the tap.

If not, the faucet may not last before it starts leaking again, making you very embarrassed.

Ask someone to help hold the faucet for you as you tighten the nut to make it steady. Keeping it yourself as you pull the nut can prevent you from reaching the maximum, and also, the faucet might lie sideways instead of staying at the center.

At this point, use the flashlight to shed some light on the dark areas as you tighten the nut.

Using a flashlight is way better compared to a headlamp as it only projects where you direct it, unlike a flashlight which enables you to see the whole place.

Step 3: Screw and Tighten the Nut.

Use your hand to screw the nut until it feels tight carefully. Even though one can feel the nut is tight using one’s hand, using a basin wrench ensures the nut is fully closed.

Clamp the basin wrench into the jaws and rotate it clockwise. Repeat the process until it becomes still and robust enough. If the nut is made of plastic, be careful not to over-tighten it as it can crack.

Whereas metallic nuts may become challenging to unscrew in the future, it is advisable not to tighten the nut.

On the contrary, if your faucet has screws or hex bolts instead of a nut, use a screwdriver with a long handle to tighten the bolt or the screws.

At some point, you may lack one of the tools to remove and tighten under sink kitchen faucet nuts. This does not mean no work can be achieved as there are many ways to kill a rat! And so the same applies to fixing loose kitchen faucet bases, as discussed in the next sub-topic.

Are you Tightening Kitchen Faucet Nut without using a Wrench?

A wrench cannot be a barrier to remove and tighten under sink kitchen faucet nuts. There are always alternatives to every problem at stake.

Step 1. Position the zip-tie on the nut’s threads, ensuring it is held firmly.

Step 2. Hold the tail of the zip and rotate it in a clockwise direction to tighten the nut until it becomes firm.

Two Coins

Money doesn’t just buy things out! Sometimes you ought to try out things in a different way and get to see their benefits.

For instance, two large coins can be used instead of a wrench to tighten a loose nut.

Step 1. Position the two coins on each side of the faucet nut.

Step 2. Use your index and middle finger to position the coins between their knuckles.

Step 3. Twist the two coins in a clockwise direction to tighten the nut.

Step 4. Rotate them until the nut is tight enough and your faucet becomes firm again.

Requirements

You will require a flashlight or headlamp to project light beneath the sink as you tighten the nut and an adjustable basin or sink Wrench.

Also, clear off any dust particles beneath the sink to prevent them from entering your eyes. You can wear a face mask for the better.

Step 2: Find the Nut Holding the Faucet Base and the Head Together

Use a flashlight or a headlamp to locate the nut beneath the kitchen sink.

Whether you are using an adjustable basin, a twist, or a sink wrench, put it in a sizable position on the nut and rotate it in a clockwise direction.

Step 4: Tighten It

This stage determines whether your kitchen faucet will become loose in the future or not.

Under-tightening or over-tightening the nut will result in the frequent loosening of the nut.

To stop this problem once and for all, ensure you tighten enough, being careful not to over-tighten or under-tighten the nut.

Step 5: Test the Faucet.

To confirm whether the problem is over, test the faucet to see if it is firm. Calmly move the tap to and fro to see if it moves. If it does not move, your problem is solved for good.

How to Tighten a Tight Space Faucet?

For better performance, the use of a basin wrench works best. A basin wrench is a unique plumbing tool designed to remove or tighten a kitchen faucet nut. It is an easy-to-use tool that everyone doing a DIY on their loose sink should possess. It does an incredible job on the faucet as compared to other devices.

Besides that, it does not require special skills to use it. It is simple and easy to use.

Below is a guideline on how to tighten a tight space faucet using a basin wrench;

Step 1: Apply a Lubricant on the Threads of the Nut

The oil helps for the smooth rotation of the nut into the faucet. However, it is optional to use oil.

Step 2: Adjust the Head of the Wrench.

Position the head of the basin wrench perpendicularly to the shaft in the clockwise direction to tighten it.

In order to identify the correct positioning of the Wrench head, the claw should grip the nut as you project the Wrench in the desired direction.

If you position the head backward, the grip of the claw will slip off the nut.

Step 3: Tighten the Nut.

Ensure that you fit the head of the basin wrench around the place, mounting the nut so that the ridge jaws of the claw grip the edges of the nut.

Use the T-bar at one end of the basin wrench to hold in place and tighten the nut.

You can use one hand to push the bar sideways and lever it, or use two hands on the T-bar to tighten the nut to make it more stable.

Step 4: Turn the Faucet.
