Its unique dimensions allow the Gutter RetroDrain to be installed within 9-in. wide box type gutters, near parapet walls or other tight areas. The patented RAC Backflow Compression Seal provides a proven plumbing connection with the existing leader pipe. Available in 3-in. and 4-in. sizes.
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.
