Have you started to hear some strange sound coming from inside your toilet? Toilet gurgling is one of the common plumbing problems that we deal with. But can this mean any underlying problems that require immediate attention? In this article, we will tell you the top 3 reasons why your toilet makes gurgling noises. And also why you must never ignore this problem.

What causes my toilet to make gurgling noises?

When there is a blockage in the drainage system, the air instead of flowing out is built up creating negative pressure inside the pipe. This negative pressure is released from the drainpipe into the toilet bowl in the form of gurgling sounds or bubbling.

So, rumbling or gurgling sound from your toilet could be something serious that needs professional intervention or something that could be tackled easily using DIY methods. This can be only analysed if the proper cause leading to this problem is established.

So let’s first understand the common possible causes of gurgling toilet:

1. Clogged drains

As we already discussed, blockage in your drainage system is the main cause of this problem. Clogs can happen due to flushing down toilet papers, sanitary pads or if you have a curious kid at home then it could be almost anything !
Minor blockages can be easily removed using a plunger. A good few plunges should do the job of clearing the clog. If not then try calling us, your local plumbing and drainage experts.

2. Blocked Vent Pipe or Improper ventilation

Plumbing vents play an important role in releasing the gasses outside through the drain and not inside our homes. If there is a block in the vent pipe or it isn’t ventilated properly, then a reverse suction is generated. This can cause the air trapped inside to backflow leading the toilet to bubble or gurgle.

3. Blockage in the main sewer system

At times, the blockage caused in the main sewer system can also lead to gurgling toilets and sinks. Now to solve this problem, you will need to know if the blocked drain is a shared drain or not. If the blockage has happened in the shared drain, then your local water authority will have to address the problem. The best way to find out whether you have a shared drain is by contacting a professional plumbing and drainage company like us to conduct a drain survey.
