What causes sewer odors and small flying insects inside the house?
This is a common problem in current residential buildings. When the range hood or exhaust fan is turned on, it creates negative pressure in the room. Under the action of atmospheric pressure, the indoor and outdoor air pressure is balanced, and the air drawn out 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 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, their effect is limited and only addresses the symptoms, not the root cause. Our Qianjia brand ventilation constant pressure machine solves the negative pressure problem at its source and solves the problem of sewer pipe backflow.
