The efficiency of the new drain is realized through a redesigned system geometry, which optimizes the flow at lower head depths.

The new drain delivers watertight, reliable performance, limiting the risk of leakage and water damage from heavy water flow due to rain, melting snow, and other types of weather events.

The new drain eliminates the need to cut separate holes in the roof for overflow drainage.

The dome's patented design increases surface area up to five times or more.

Four new options help create unlimited top-level adjustment.
