This process starts as soon as you flush the toilet. The water stored in the tank gets released into the toilet bowl, where the water waste gets carried down under the drainage system.

The wax ring then provides a waterproof seal close to the waste pipe that meets the toilet, ensuring that it doesn’t allow any leakage under the toilet zone.

It Controls the Odor and SmellIt Controls the Odor and Smell

To prevent any sort of sewage gas from leaking out and creating an unpleasant atmosphere, the wax ring creates an airtight seal to prevent that gas from leaking out.

When in proper condition, the gas rises up to the toilet and stays there until the next flush.

Make sure to understand this concept that whenever there is a faulty and unpleasant smell in the bathroom, it is caused by a broken or leaked toilet seal and you need to reseal the toilet to the floor.

Sitting and getting up from the toilet seat allows a force that applies. So, apart from the gas leakage and water stoppage, the wax ring also provides the toilet with stability and flexibility.
