Features & Benefits

Water flow is up to 2.5 times faster versus the original Hercules Drains.
Bright yellow strainer domes are cast aluminum for strength and durability, and remain visible on the roof for improved safety.
U-Flow Seal exceeds the ANSI/SPRI RD1 standard for a secure, watertight connection.
Saves time and money by allowing easy installation from the rooftop without disturbing occupants.

Product Use

Hercules-Plus RetroDrains are designed to replace existing new construction drains in re-roofing applications. Installed from the roof surface, Hercules-Plus RetroDrains are engineered to be installed without removing the existing drain fixture. Hercules-Plus drains have a mechanical seal for direct connection to existing PVC or cast iron plumbing.

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.
