What causes sewer odors and small flying insects inside the house?
Release time:
2021-01-22
This is a common problem in residential buildings today. When the range hood or exhaust fan is turned on, it creates negative pressure inside the room. Under the action of atmospheric pressure, the indoor and outdoor air pressure is balanced, and the air extracted by the range hood and exhaust fan is forcibly supplemented. Due to the strong sealing performance of doors and windows, it is difficult for air to Enter through the gaps, and can only Enter through the sewer pipes.

Due to the strong sealing performance of doors and windows, it is difficult for air to enter through the gaps, and can only enter through the sewer pipes, causing indoor odors and small flying insects to fly into the room. Although there are existing deodorizing floor drains, the effect is limited, and it only treats the symptoms, not the root cause. Our Qianjia brand ventilation pressure machine solves the problem of negative pressure from the source, solving the trouble of sewer pipe backflow.
