This 110 mm square hopper is designed for use with most underground drainage systems. Typically a waste pipe operates at 30% capacity, but the hopper increases efficiency to closer to 100%. Attach it to a rainwater downpipe or sink waste outlet. The hopper will fill with water before discharging it to the drains, creating a syphon effect and ensuring the water clears quickly.
