Toilet Making Noise When Not In Use

Toilet Making Noise When Not In Use [Fix Your Cause Now]

When your toilet makes unusually loud noises, it might be unsettling, especially if you have never experienced this before. 

However, determining whether a toilet noise necessitates a visit to a plumber may be both confusing and worrisome.

There are several issues that can arise with your toilet, ranging from a basic running toilet (which is usually resolved by a simple valve change) to a toilet overrun or more severe issues such as water leaks. 

When the toilet continues to make noise, it is the first sign that anything is incorrect. There are several probable explanations for your toilet to make noise when it is flushed or when it is not in use.

When do toilets make noise?

The latest and greatest technology now exists on the planet that lets us monitor all conditions of a toilet bowl so that when it starts making noise you know it and can stop it. 

This is an important and necessary step towards eliminating the human caused global warming that we all know is causing the rise of seas as the temperature gets higher.

When the ocean is warming it absorbs all the greenhouse gasses that are in the air. This heat is trapped in the waters and is causing a rise in the ocean levels, which are the cause of more flooding in the United States.

So you can see by this, that we no longer have so much time to solve the problem. Climate change is a serious issue and can’t wait. 

So to help solve the problem, I’d like to propose that we make sure our toilets are making noise as they should, so that we can stop the warming of the oceans. 

Yes, our toilets are now made with technology that makes the noise they should when the temperature gets high. 

Why is my toilet making noise when not in use?

We all have some degree of toilet noise in our homes. Water flushing pipes, running faucets, the odd flush or two, or the occasional thump that sounds like the toilet is unzipping. 

Or even worse, it might be a “gurgle” sound like the water is backing up when you’ve reached the last level in the chain. So why is this noise happening?

In a standard toilet, the water enters the toilet bowl and then flows into the pipe that returns water to the tank above.

Since there is a gap between the toilet bowl and the pipe, sometimes small amounts of water in the toilet can “back up” through this small gap. 

This gurgling noise is also the reason we use a water softener with ion exchange resin. The softeners remove calcium and magnesium minerals in the water and replace them with other ions.

The noise is caused by the trapped air that is in the pipe because the pipe is too small to let the water flow freely. 

When there is an opening at the top of the toilet there is more chance for water to back up. This also explains the reason why you need to pull the chain to stop the flush. The chain closes the opening.

Water can only exit by flowing down the outside of the pipe and out into the tank.

If your toilet is noisy in this way there are solutions for you. You can change the pipe to a larger diameter pipe which would make it easier for the water to move freely. 

You can also add an aerator to the toilet tank, which has holes that allow air to enter the tank, but not water. 

The water will be less dense and thus flow more freely into the tank. You can even try to locate the toilet in a slightly more open space, such as in a laundry room, a walk-in closet, or a bathroom without a door.

What are the causes of toilets making noise when not in use?

When a toilet is not in use, a number of sounds can be heard. This is due to the sounds produced by the pressure tank during the lifting of the water from the tank, the closure of the toilet seat, the back flow, the flush and the sounds inherent in the operation of a pump. 

Normally, the sounds produced from the various components will vary according to the type or make of the product.

When the toilet is used, the sounds in the tank are audible to users in the bathroom through the floor. But when the toilet is not in use, there is a small sound that travels through the floor in all directions. 

This noise is normally produced by the small noise and the noise from the components of the toilet that produce a sound. It is not normally heard if the toilet is flushed, but when the toilet is used, and the tank is emptied, the noise can be heard at the user’s location. 

The noise of the toilet can actually be heard in neighboring floors, particularly when the toilet is flushed more than once in succession. 

Some floors do experience a different noise than others and some floors can even be quiet while the toilet is being used in other floors.

 Toilet noises can be heard on another floor if a toilet is flushed, because the sound will travel through the floor and into other floors. This could even result in toilet sounds being heard from a floor which is not even using the toilet. 

This will only be the case when the other floors are using the toilet and you will experience the toilet noises as soon as you leave the bathroom. 

So you can imagine that even floors which are not using a toilet can experience the sounds produced by the toilet just by the proximity that the toilet is located in. 

There is a difference between noise from the toilet in the next floor which is in use, and the noises traveling as a direct result if the toilet is on your floor which is not in use.

There is more chance that the toilet will make some noise when your floor is being used compared to a floor which is not being used, because these toilet noises will start as soon as the toilet is flushed and the water is turned on, whether the floor that is using the toilet is on or off. 

The sounds from the toilet will start no later than the first time the toilet is flushed. As soon as it is flushed, the sound will travel through the floor and into the other floors. 

But while the other floors are not using the toilet, this will not be the case and the noises do not start until you leave the bathroom and your door is open.

Types of toilet noises

The following sounds typically accompany the use of toilets and urinals. Some sounds may be produced by toilets located on the exterior of buildings.

• The sound of water hitting the bowl of a commode is a characteristic feature of the sound of toilets in public buildings, and the same action occurs at urinals in most public buildings where they have toilets. 

The toilet sounds may be masked by soundproofed windows or by the sounds of other commodes or urinals. In offices or schools, soundproofing is not practicable and some toilet sounds must be heard. They can be annoying but some people welcome a familiar sound.

The sound of commodes is also heard in unisex public and semi public restrooms – restrooms in schools, hospitals, airports, hotels etc.

Most cities and towns – particularly those in colder climates, have public restrooms in which there are two urinals and one or more commodes located in an opening to the room and on the wall. In unisex facilities, the commode is not considered a private facility. 

Most public restrooms have sounds that accompany a flush. In unisex restrooms, the sound of the flush is a fairly distinctive sound.

• The sound made by a commode when flushed is very characteristic of a toilet and it is also a commonly used sound for identifying individual toilets.

The sound generally consists of the falling of a stream of water for the first five to twenty seconds followed by a gurgling sound. 

Some commodes have a distinct whistle. This sound is so distinctive that it can be identified in most locations.

• The sound made by a commode is distinctive and it is often referred to as the “sound of a toilet.” The sound typically consists of a short “ping” followed by a gurgling sound, particularly when there is a small quantity of standing water. It resembles the sound of a running shower or rain outside – a distinctive sound.

• The sound of a commode being flushed is also distinctive.

It most frequently consists of a very brief “ping” followed by a gurgling sound. Frequently the gurgling sound consists of a series of sounds, a “bubble” sound and “quack” when the water level rises high enough to produce a splash. 

Some toilets, in cold weather, may produce the sound of a toilet flushing in midwinter.

• The sound of a toilet flush is also distinctive. It may have the same characteristics as the sounds of a commode being flushed, particularly if it was flushing a very small quantity of water.

The toilet flush sounds similar to a shower or shower curtain.

 They are usually only a few seconds long; some toilet flushes may be more prolonged. The sound can be heard in both cold and temperate climates.

• The flush of a toilet may include more than one “gurgle” in rapid succession, and frequently it has a “watermelon” – a gurgling sound with a sound as loud as the sound of a gong. 

This is a characteristic sound, although no one is sure of the origin of the phrase. It is not clear if “watermelon” is an actual sound, as some people state it, or if the perception is a mental association with the sound of a watermelon at a musical concert.

A single “gurgle” is also very distinctive. The noise that can be heard is usually the noise of a shower or shower curtain when used.

• The sound of a toilet flush is a characteristic feature of many toilets, and is always heard when the flush is being used.

It is a short noise, much shorter than any other sound in the bathroom. It is generally similar to the noise made by a shower or a shower curtain in bathrooms and it is occasionally louder. It is not usually as loud as a shower can be.

• The sound of a toilet being used is generally heard for a while longer than the sound of a toilet flush.

In many cases, there is no distinct sound.

 The person can hear the sound but may be unable to determine in which toilet the sound is being made (e.g. if there are several toilets in a room). 

When there are a number of toilets on a floor, no distinctiveness can be distinguished, and if there is no water present, it may be impossible to even know that it is being flushed.

• The sound of a toilet being used is similar to the sound of a running shower or shower curtain. This is another characteristic sound of toilets.

The flushing sound is followed by a period of silence while the water drains from the commode.

• A flush of a commode will usually leave the water in the commode slightly above the floor.

How to resolve toilet noise when not in use?

Toilet sound is a constant sound coming from your toilet without any reason, because when you’re about using is a time for you to relax and relax. But with every flush a noise occurs, and it can be heard from various distances. There are two major reasons that toilet sound, whether in public or in private:

The first is that the toilet is not filled with a certain amount of water. Not more than 3 or 4 gallons. Some say that the sound occurs when the volume of water that can make toilet noise.

The second reason is that the toilet has a malfunction or the volume is not enough to fill.

If you want to resolve toilet noise when not in use, you just need to understand the two main reasons. We will explain:

The first reason is related to the amount of water in the toilet. It is not necessary to fill up each time that you flush it. You only need to fill up enough. You can go to the home page of and get details on various solutions to resolve the sound.

The second reason is related to the functionality of the toilet. With modern toilets, you can easily resolve the sound by using their volume.


When you’re done using the toilet, it shouldn’t make any noise. Although some components may experience wear and tear, leading the entire toilet system to produce noise.

Remember that before you can conduct the suitable treatment, you must first grasp the problem with the toilet.

If you’ve done everything else and you still hear a gurgling or loud noise while your toilet isn’t in use, you’ll most likely need to call a professional for help.
