PEHD gulley 90x90/88 straight S12.5, black color, QS (Quick Stream) 3003738

Efficient roof water drainage – Quick Stream WAVIN drain hopper

This simple QS 90x90 drain hopper, made of polyethylene (PE), is a key element of the WAVIN Quick Stream system, designed for efficient drainage of flat roofs. Its design allows for increased installation throughput, even when using pipes with a smaller diameter. This is an ideal solution for both professional installers and building owners looking for a reliable drainage system.

Design and application

The drain hopper combines the function of a simple connector and an element enabling a change in the direction of water flow. Made of durable high-density polyethylene (HDPE), it provides corrosion resistance and long-term operation. Welding spigots allow for a tight and durable connection with other elements of the Quick Stream system. The length of the drain hopper is 200 mm, and the outer diameter of the pipe is 90 mm. The normalized dimension ratio (SDR) is 26, which guarantees adequate mechanical strength.

Advantages and benefits

• High throughput: The Quick Stream system, which uses this drain hopper, utilizes the phenomenon of negative pressure to increase drainage efficiency.
• Durability and resistance: HDPE material provides resistance to weather conditions, corrosion and mechanical damage.
• Easy installation: Welding spigots allow for quick and tight connection with other system elements.
• Versatility: The drain hopper is compatible with the remaining elements of the Wavin QuickStream system, allowing for the construction of complex drainage installations.
• Reduced pipe diameter: The ability to use pipes with a smaller diameter translates into material savings and construction costs.
• Reliability: The Quick Stream system ensures reliable and safe drainage of water from the roof for a long time.
• Round shape/cover type provides an aesthetic appearance of the installation.

The Wavin QuickStream system is not only installation elements – it is a comprehensive solution for efficient drainage of rainwater from flat roofs, which proves itself in practice and provides users with peace of mind for many years.
