The Kisner KADS Parapet Drain provides a durable, watertight solution for horizontal drainage through parapet walls on flat roof systems. Available in 3” (62–75 mm) and 4” (90–110 mm) outlet sizes, it offers a reliable, sealed connection to standard pipework and long-lasting performance in all weather conditions.
The Kisner KADS Parapet Drain is engineered for efficient lateral water discharge through parapets and upstands in flat roofing systems. Each drain includes an integrated gasket that ensures a tight, secure fit to existing pipework, preventing backflow or leakage under pressure.
Constructed from high-quality polypropylene (PP), the drain body offers excellent resistance to thermal expansion, UV exposure, and mechanical stress. The unit is supplied with an 18” square EPDM membrane flange for seamless integration into EPDM roofing systems, ensuring a fully watertight installation.
Some assembly is required during installation — the membrane must be properly bonded to the drain flange using an approved EPDM adhesive to maintain system integrity.
Compatible with EPDM roofing systems (attach using EPDM adhesive)
Suitable for connection to PVC, HDPE, or cast-iron pipework
Ensure mating surfaces are clean and dry prior to welding or bonding
Can be paired with Kisner KADS Parapet Drain Leaf Guards for debris protection
Store in a dry, temperate environment (5–25 °C). Avoid deformation of the drain body or flange during storage. If exposed to cold conditions, allow to return to room temperature before installation.
Kisner Kads trims and finishing accessories are designed to protect roof edges while enhancing aesthetics. Their components offer a clean, professional finish and long-term weatherproofing support.
