Retro fit roof drain designed to fit into existing drain leaders in re-roofing applications
One-piece spun aluminum body, heavy duty cast aluminum strainer dome, and clamping ring provide 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.
Features & Benefits
- One-piece seamless body provides strength and durability without separation of the flange from the stem.
- Extra large flange allows positive attachment of roof flashing membrane while the sump area facilitates drainage.
- Cast aluminum strainer dome and clamping ring.
- 12-in. long drain stem accommodates most existing field conditions with longer lengths available.
- Incorporates U-Flow Seal technology for a secure, watertight connection.
- Also available with the cast-aluminum SuperDome.
- Saves time and money by allowing easy installation from the rooftop without disturbing occupants.
Application
OlyFlow RetroDrains are designed to replace existing drains in re-roofing applications. Installed from the roof surface, OlyFlow RetroDrains are engineered to be installed without removing the existing plumbing or fixture while providing a watertight connection to the roof system and the existing plumbing.
As with all building materials it is the responsibility of the installer to review its usage with a design professional to confirm safety, compatibility and acceptance with the roof cover manufacturer as well as local building codes.
