Dual Roof Drain
Product: Big Daddy RD-800 Series
The new, exclusive Watts Big Daddy™ RD-800 Series dual roof drains provide outstanding leakage protection, durable construction and ease of installation. This drain eliminates the need to cut separate holes in the roof for overflow drainage. In independent lab tests, the 10 in. outlet model achieved a 1,368 gpm flow rate, demonstrating flow rates much higher than multiple single roof drain and overflow units can deliver.
