Smaller Pipe Diameter, Single Point of Discharge, Reduced Material Cost, Eliminates Slab Penetration Costs
This labor-saving, 15 1/4" (390) siphonic roof drain can be installed from above the roof deck, solving the need for work inside or under the facility and significantly simplifying installation. For use in engineered siphonic drainage systems, this drain will clear heavy wastewater accumulations faster than traditional roof drains. Made of corrosion resistant Duco coated cast iron and topped by a polyethylene dome strainer, it can be installed in flat roofs of any construction.
Pro Tip: The siphonic drain is just one component in a siphonic drainage system. These systems should always have the approval of a plumbing engineer, licensed in the locale where the installation is to occur.
