Our 7-1/4 Roof-Ceptor Indirect Waste Drains are designed to collect condensate and other wastewater coming from rooftop air conditioning units, cooling towers and other mechanical equipment. The Duco coated cast iron bodies are fabricated with a combination flashing clamp and solid water dam. The dam prevents storm water from entering the drain and the flashing clamp grips roofing materials without puncturing for a watertight installation. A secured cast-iron dome protects drain lines from debris.
