Specialty Drains

Product Use

All are constructed of aluminum and available in 3- and 4-inch sizes. All offer a patented U-Flow mechanical seal for a tight connection to the drain leader, and all can be installed from the rooftop without disturbing building occupants.

OlyFlow RetroDrains are designed to replace existing drains in re-roofing applications. Installed form the roof surface, OlyFlow RetroDrains are engineered to be installed without removing the existing plumbing or fixture and feature a mechanical seal for a watertight connection to PVC or cast iron drain leaders.

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 as well as with local building codes.
