Noise reduction: Due to the unique structure of the ultra-quiet spiral single riser drainage system, the sewage adheres to the inner wall of the pipe to form a spiral drop, avoiding the collision between water and air, and water and the pipe wall, reducing the vibration of the pipe and making the drainage system more effective. The noise is greatly reduced. The building drainage system with a noise index of less than 45 decibels has been tested by the national authority, which is much lower than the current noise of other building drainage systems, ensuring people's physical and mental health, and effectively improving the comfort of living and office environments.

Strong drainage capacity: The existing drainage system has chaotic flow patterns and large air pressure fluctuations in the riser. The water flow in the horizontal branch pipes forms a large water flow at the riser confluence and the water plug problem at the bottom of the riser cannot be solved, resulting in unbalanced pressure in the pipeline, causing upstream Negative pressure suction is formed in the pipeline, and positive pressure spray occurs downstream, which seriously affects the drainage capacity. The ultra-quiet spiral single riser drainage system forms a smooth air column in the center of the riser, which effectively ensures the pressure balance in the pipeline and greatly improves the drainage capacity of the system.
