If you often face a strong odor coming from the septic tank even though you have spent a lot of time cleaning the toilet, it may be because the toilet rabbit has a problem leading to poor anti-odor effectiveness. .
What is an anti-fouling rabbit?
In the animal kingdom, a rabbit is a small rodent with long, adorable ears. In construction, the rabbit is a small but extremely important device in preventing odors from refluxing.
At first glance, you might think that the anti-fouling rabbit is some kind of device shaped like a real rabbit. However, in reality, it is a piece of water pipe with a curved shape, the two ends of the pipe are protruding like a “rabbit ear” that is inserted into the toilet’s waste pipe, so if you don’t like it, you can call it a rabbit. this device is an anti-fouling siphon tube…not wrong. Thanks to the special design, the rabbit acts as a stopper to help prevent odors coming from under the septic tank, helping the toilet not be haunted by the smell of the septic tank. The rabbit in addition to anti-fouling toilets, this device is also used for sewers, sinks, etc. with many different sizes and materials.

Why should the toilet be fitted with a rabbit?
The toilet waste pipe system is always designed in a straight line and extends from the manhole to the cesspool. Therefore, the smell of waste can go along the pipe and back up into the toilet. Besides, some insects will also easily “attack” into your home from the sewer. Therefore, the simple way to handle a toilet with a bad smell from the beginning is to install a rabbit anti-fouling toilet.
Structure and Operation
Although it is only a small device, because of its anti-odor effect, it is made up of many different parts, including:
- Rubber gasket;
- Navel discharge;
- Screws;
- Siphon;
- Waste pipes;
Normally when pressing the toilet flush button, the water from the top of the tank will pour down at a fast speed and bring all the waste down. However, due to the special design, when the water flows through the rabbit, there will always be a certain amount of water retained to prevent odors from backing up.
Does the toilet rabbit really help the toilet completely anti-foul?
The rabbit is designed to prevent odors from the toilet, preventing the smell of the septic tank from refluxing. However, a number of problems can occur that make the anti-fouling effect of this device not really as expected, such as:
a) The water level in the toilet rabbit is too low:
This was determined to be a technical error when installing toilets. Normally, for the rabbit to have the highest anti-fouling effect, the water level in the toilet and the rabbit must be equal and about 10cm tall. However, when installed incorrectly, the lower water level in the rabbit will lead to gas reflux from the toilet to the toilet, 1OO% you will encounter an unpleasant smell when using.
Therefore, it is recommended that you contact professional units when you need to install or repair a toilet rabbit. Do not arbitrarily follow the instructions on the internet without experience.
b) Waste accumulated in the rabbit:
We often talk about the problem of waste building up in pipes causing odors, and that exact location is in the rabbit. In fact, the curved design helps prevent odors but also creates an obstacle for dirt and toilet paper (temporarily called garbage) to stick. Over time, this amount of garbage will increase, causing blockages and unpleasant odors.
To fix it, you can use EcoClean Septic probiotics to pour into the toilet and flush to clean the garbage that is accumulating in the rabbit and the septic tank. Ideally, you should let the probiotics soak in the toilet overnight before flushing to let the bacteria “eat” the waste.
Toilet odors aren’t just annoying, they affect your mood, and breathing them in frequently can make you and your family sick. Although the anti-fouling rabbit is not absolute, this is absolutely a device you should have when installing a toilet. In addition, you should also pocket some simple and easy ways to deodorize the toilet at home.
