Kayflow SuperDeep 170mm Black Hopper
High-Capacity Hopper for Commercial Rainwater Systems
The Kayflow SuperDeep 170mm Black Hopper is a robust, high-capacity fitting designed to efficiently channel rainwater from multiple gutter or pipe runs into a single 110mm round downpipe. Part of Kayflow’s SuperDeep 170mm range, one of the largest and toughest commercial guttering systems on the market, this hopper ensures maximum water flow management for large roofs, industrial units, and commercial buildings.
With a generous 170mm reservoir and a market-leading independently tested flow rate of 4.3 litres per second, the SuperDeep system rapidly directs rainwater into the downpipe, preventing overflow and protecting building structures from water damage.
Hoppers are typically used to collect flows from different rainwater pipes—such as upper and lower roof levels—and channel them into a single outlet. While occasionally used on older properties with combined drainage systems, their main role is to provide a central collection point for high-capacity systems.
Manufactured from durable, UV-stable uPVC, this black hopper is resistant to fading, rust, and weathering. Its simple, secure installation and low-maintenance design make it a reliable choice for professional and long-term applications.
