In the summer, many families have encountered the situation of the floor drain odor return, serious will also encounter sewage overflow, insects crawl out and other problems. What is the reason for this?
It turns out that the floor drain is the adjoining port of the sewer pipe and septic tank and the living space, and the old floor drain relies on the floor drain’s own water storage to form a water seal, which separates the living space from the piping system. Once the “water seal” is damaged, the sewer and even the septic tank are integrated with the indoor space, and the toxic and harmful gases such as fecal odor, carbon monoxide, carbon dioxide, methane and hydrogen sulfide emitted from the sewer will be harmful to human health.
Countermeasures: When using floor drains, you must prevent the water seal from drying out and fill it with water regularly. If you want to travel for a long time, it is best to seal up the floor drain with a cover.
