In summer, many families have encountered the smell of floor drains, and even serious problems such as sewage overflow and bugs crawling out. What is the reason for this?
It turns out that the floor drain is the connection between the sewer pipe and the septic tank and the living space. The old-fashioned floor drain relies on the water stored in the floor drain to form a water seal, and the living space is isolated from the piping system by the water seal. Once the “water seal” is damaged, the sewer or even the septic tank will be integrated with the indoor space, and the emission of toxic and harmful gases such as skatole, carbon monoxide, carbon dioxide, methane, and hydrogen sulfide in the sewer will cause harm to human health.
Countermeasures: When using the floor drain, the water seal must be prevented from drying out, and water should be injected regularly. If you want to travel for a long time, it is best to seal the floor drain with a cover.
