Constructed of aluminum and stainless steel components with a large, plastisol coated flange for hot air welding of PVC-type roof membranes. The drain flange has a depressed sump area and an oversized, low profile strainer dome to facilitate the easy drainage of all water from the roof surface. The RAC PVC RetroDrain incorporates the patented technology of the RAC Backflow Compression Seal providing a mechanical watertight connection.
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.
