Siphon rainwater hopper is a key component of Siphon rainwater system and also a rainwater collecting device. Rainwater bucket is made of high quality 304 stainless steel, aluminum alloy pressure ring and flow guide cover, and has the characteristics of corrosion resistance and extrusion resistance. The strong anti-vortex function of the siphon rainwater hopper can well prevent air from entering the whole system through the water flow at the inlet of the rainwater hopper, and form a water seal to completely block air from entering when the water level in front of the hopper rises to a certain extent. And make the rain water smoothly submerge and drain into the drain pipe. The siphon type rainwater hopper minimizes the depth of accumulated water in the gutter, minimizes the rainwater load borne by the roof, and increases the rated flow rate of the rainwater hopper.
