Scupper Thru-wall RetroDrain

Designed for existing through-wall/side-wall or scupper drainage pipes, the aluminum and stainless steel drain components provide durability and compatibility with single ply, BUR and modified bitumen roofing systems. A metal clamping assembly creates a compression type termination in both vertical and horizontal wall flashings. The Scupper RetroDrain features the patented RAC Backflow Compression Seal for attachment to PVC or cast iron leader pipes, and a removable drain strainer. Available in 3-in., 4-in., 5-in., and 6-in. sizes. Custom configurations are also available.

Features & Benefits

  • Pre-punched drain flange provides stable attachment to the wall and roof deck.
  • The RAC Backflow Compression Seal is quickly activated at drain flange level to protect the roofing system and building contents from water backup damage.
  • Includes a 0.125-in. metal clamping ring assembly provides a compression type termination for the vertical and horizontal roof flashings. Stainless steel studs and lock nuts secure the clamping ring assembly to the drain flange.
  • 0.060-in. thick drain strainer is easily secured to the drain body with four stainless steel wing nuts and provides protection against rooftop debris.
  • Features a 9-in. stem.
  • Simple and easy to install, saving the contractor time and money.

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.
