Description
In recent years, heavy rainfall from intense storms or typhoons has caused flooding damage to semi-basement homes and basements due to sewage backflow. In response, we have developed a backflow prevention device for catch basins that can block sewage from entering residential properties. The device can be easily installed and maintained without the need for special tools or adhesives.
