The Kisner KADS Parapet Drain provides a reliable, watertight solution for horizontal drainage through parapet walls in flat roofing systems. Available in 3” (62–75 mm) and 4” (90–110 mm) sizes, it ensures a secure, sealed connection to standard drainpipes for long-term performance in demanding conditions.
The Kisner KADS Parapet Drain is purpose-designed for efficient lateral water discharge through parapets, upstands, or wall outlets in flat roof systems. Each unit features a factory-fitted gasket, providing a tight and durable seal to existing drainpipes and preventing leakage or backflow under pressure.
Manufactured from high-quality polypropylene (PP), the drain body offers excellent resistance to UV radiation, thermal cycling, and mechanical stress. It is supplied with an 18” square butylene fleece flange, which must be securely bonded to the roofing membrane to ensure a seamless, watertight connection.
This robust, low-maintenance component ensures effective drainage performance, even under variable weather and temperature conditions.
Designed for flat and parapet drainage applications
Compatible with PVC, HDPE, and cast-iron pipework
Use appropriate roofing adhesive or primer to bond the butylene fleece flange
Can be fitted with Kisner KADS Parapet Drain Leaf Guards for debris protection
Store in a clean, dry location between 5–25 °C. Avoid impacts or deformation of the drain body and flange. If stored in cold conditions, allow the drain 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.
