Hercules®-Plus Roof Drain
With integrated vortex breaker technology, the Hercules-Plus RetroDrain can provide up to 2.5 times greater water flow to reduce excessive water and weight from the roof faster. Hercules-Plus drains are available in 75 mm, 100 mm and 150 mm sizes.
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.
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.
