Hercules RetroDrains have a one-piece spun aluminum body, heavy-duty cast aluminum strainer dome, and clamping ring for strength and durability. The Hercules RetroDrain incorporates U-Flow® Seal technology for a mechanical watertight connection to PVC or cast iron pipes to prevent water from backup damage. Available in 3-, 4-, 5- and 6-inch sizes.
Hercules RetroDrains, the industry’s most popular retrofit drain, are available with a variety of options to support any project, including TPO or PVC coated flange for direct membrane attachment, copper stem and flange for more corrosive environments, and with OMG’s exclusive Vortex Breaker Strainer Dome, which can increase flow by up to 2.5 times.

Hercules RetroDrains are designed to replace existing new construction drains in re-roofing applications. Installed from the roof surface, Hercules RetroDrains are engineered to be installed without removing the existing drain fixture. Hercules RetroDrains have a mechanical seal for direct connection to existing PVC or cast iron plumbing that meets the ANSI/SPRI RD-1 standard.
As with all building materials, it is the responsibility of the installer to review product use with a design professional to confirm safety, compatibility and acceptance with the roof cover manufacturer and local building codes.
