A ppro va l s & S TA N D A R D S ANSI/SPRI RD-1 – developed by SPRI (Sheet membrane and component suppliers to the commercial roofing industry) a certified canvasser of ANSI (American National Standards Institute), and features a test protocol designed to assure a leak-free connection to existing plumbing. IAPMO PS 97-96 – a standard plumbing industry test designed to check for leakage at connections under a 10 foot head of water for a 24 hour period. This test was performed by the Smith-Emery Company, a nationally recognized independent test laboratory providing physical testing of construction related materials. The Scupper RetroDrain produced no leakage. P H Y S I C A L D ATA The data below is constant for all OMG Scupper RetroDrains.

MADE IN USA RP10130C PRODUCT DESCRIPTION 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. Scupper RetroDrain I N S T A LL A T I O N P R O C E D U R E F or U se W ith All types of roof covers. J ob P reparation The existing leader pipe shall be cleaned of excess bitumen build-up, dirt and debris. Remove the clamping ring assembly and bolts from the existing drain and discard. If required, comply with roof manufacturer’s directions for additional cleaning or detailing. STEP 1 Important – The aluminum activation cone may have settled into the backflow seal during shipping, which may partially activate the seal. To deactivate the seal, simply push down on the top of the two backflow bolts. Note: The top of the tapered metal cone should remain inside the bottom of the urethane seal. Do not fully disengage the cone from the urethane seal. STEP 2 Place the Scupper Retrofit Drain Assembly into the existing drain leader (vertical or horizontal) pipe. The drain flange(s) should be in contact with the surface of both the wall and roof. STEP 6 Install the metal clamping assembly into position by hand-tightening the lock nuts provided. Do not overtighten. STEP 3 Using the pre-punched holes in the perimeter of the flange, secure the drain flange to the substrate with appropriate fasteners. STEP 4 Hand tighten the 7/16-in. bolts on the backflow rods to activate the seal. Alternate tightening between the bolts for an even seal expansion. Do not overtighten. VERTICAL INSTALLATION STEP 5 Install roof flashing material into place per primary roofing manufacturer’s drain flashing details. STEP 7 Install the drain strainer over the center of the drain opening and secure to 4 studs with the wing nuts provided. For technical assistance contact OMG at 800.633.3800.
