Manufactured with copolymer resin that is compatible with any roofing system, PC/PET drains can even withstand the torch heat associated with torch down roofing applications. Molded one-piece body - without seams that could split and leak. The PC/PET RetroDrain incorporates U-Flow® Seal technology for a watertight mechanical connection. Also available with the cast aluminum SuperDome® strainer in 3-in. and 4-in. sizes.
OlyFlow® RetroDrains are designed to replace existing drains in reroofing 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.
