Sure, when you flush your toilet – this isn't exactly a silent process. However, if your toilet seems to be making strange noises nonstop, not only is this not normal, but it's also a good idea to get to the bottom of the problem as there are several things that could be going on leading to a number of problems. Learn what the noises from your toilet might just mean.

Bubbling Noise

If your toilet is making a gurgling or bubbling noise, this could be an indication of a blocked vent. The vent is basically a trap like structure that helps the wastewater properly drain from your toilet. When the vent is blocked, not only will it make this type of noise, you will likely also experience draining issues at some point.

A common reason for vent blockage is debris from animals. The size and configuration of the vent often looks like an ideal space for animals to build their nests, blocking the vent with debris from their nest. Vents may also block during winter if they freeze and get covered with ice. Attending to the vent blockage will typically resolve the problem.  

Random Flushing

Does it sound like your toilet randomly flushes? If the answer is yes, no, there is not a ghost using your toilet. The sound you hear is a signal that the toilet is losing water. This type of sound isn't just annoying, but it can also lead to higher than expected water bills.

Toilets can lose water for several reasons, including a dirty flapper that no longer secures to the base, a worn flush valve, or even a leak under the toilet due to a bolt that is worn. Whatever the case, it is important to get to the bottom of the water loss concern.

Knocking Sounds

Another sound to look out for is a knocking like sound. This sound is often an indication of an issue with your shut off valve. Just behind your toilet, fixed in the wall is a shut off valve. If for some reason, an obstruction forms, such as clogged debris, along the path from the toilet to the valve, you could hear this sound.

This obstruction could be the result of a debris, a failing valve or a host of other issues. It is imperative that you address this issue because the obstruction could lead to a significant water leak behind the wall, leading to costly damage.

If your toilet is making noises, have a licensed plumber inspect your toilet to highlight the problem and repair the necessary issues.
