Where is the toilet air return?

The air return port of the toilet is on the side of the sewer pipe, with a diameter of about 2cm, and the direction is generally opposite to that of the sewer pipe. Some toilets have a small hole in the middle of the sewer pipe, which is also an air return hole.

Siphon phenomenon is actually a phenomenon formed by the gravity and potential difference of water. In fact, it is to use the pressure difference of the water column to make the water rise and then flow to a lower place. Because the water surface of the pipeline is subjected to different atmospheric pressures, the water will flow from the high-pressure side to the low-pressure side until the atmospheric pressures on both sides are equal and the water surface in the container becomes the same height, and the water will stop moving.

Precautions:

1. When installing, do not pour cement into the toilet to prevent the toilet from cracking due to cement solidification.

2. In order to ensure the good performance of the toilet, it should be cleaned in time after use. Special nylon brushes and cleaning agents should be used, and strong acid and alkali solutions should not be used to avoid scratching the glaze and corroding the pipeline.

3. If the temperature is below zero, it is suggested to suspend the use of the toilet to avoid the watermark inside the toilet from freezing and swelling, which will lead to the rupture of the toilet. Don't hit the toilet with hard objects at ordinary times to avoid water leakage.

4. If there is residual glue in the toilet, it is suggested that it can be removed with a scraper. If there is more glue, banana oil can be used to remove it.
