Product Use

Product Use

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.

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.
