Reasons behind the 4 Most Common Noises That Toilets Make

Toilet problems are a homeowner’s worst nightmare, as there are very few things that instill fear in a homeowner other than a broken toilet. Not only are they a pain to fix but they can also be incredibly pricey to repair. This is why it’s in your best interest to make sure that your toilet is always working properly. 

One of the best ways to do this is to be attentive to signs of complications. Rarely do toilet issues come out of nowhere, as they usually stem from minor problems that progressively get worse. This is why we thought it would be useful to put together an article discussing the reasons toilets make noises even when they’re not being used. Hopefully, this article proves to be useful in helping you better understand toilet problems so you can address them as soon as possible.

Constant Running

If you hear the sound of your toilet constantly running, it can be attributed to a couple of common complications. The first being a strained or tight flapper chain. Flapper chain issues can cause the valve to stick open and cause the sound. The valve itself may also be faulty, as it is unable to stop water from leaking to the toilet bowl. Lastly, the constant running sound could be caused by float issues. If the float isn’t set properly, it can cause your toilet to constantly run and waste water.

Hissing Noise

Hissing noises, while intimidating, aren’t usually caused by serious toilet complications. For the most part, hissing noises are caused by your flapper. The flapper wears out over time and can stop functioning properly. Another potential reason could be that your toilet’s ballcock isn’t adjusted to the right levels. Luckily, these issues can be fixed by calling a professional plumber!

Bubbling Noise

If you’ve noticed that your toilet has been making a bubbling noise, then it may be time to have it checked because this noise is usually indicative of a blockage. Before calling a professional, you might also want to consider using a plunger to see if you can clear the blockage yourself. If this doesn’t work, then we recommend that you avoid trying to fix it yourself and call a plumber right away.

Banging Sound

Lastly, a banging sound is one of the noises that indicate a serious problem with your toilet. This sound is often referred to as the water hammer due to how loud it can get. The reason for this sound is usually the pressure from the pipes. What you’re hearing is actually the water hitting the valve, as it makes a loud banging sound when it collides with it. However, this only happens when the pressure gets too high. We recommend that you take this problem seriously as it can cause real damage to your pipes and will lead to them deteriorating rapidly. Since this isn’t something you can fix yourself, we recommend calling in a plumber to fix this issue!


While the sounds may be intimidating, it’s best to keep a level head and try to address the problems that you are able to fix yourself. With that being said, it is crucial that you don’t overextend yourself. If you don’t have the necessary expertise, it would be best to leave it to the professionals to avoid even more serious complications!
