Features & Benefits

- Available with a U-Flow cast aluminum strainer dome. They can also be retrofitted with the yellow Vortex Breaker Strainer dome.
- Saves time and money by allowing easy installation from the rooftop without disturbing occupants.
O-Ring RetroDrains are designed to replace existing drains in re-roofing applications. Installed from the roof surface, the 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.
