PEHD inspection chamber 75x75/88 straight S12.5, black color, QS (Quick Stream) 3003736

Efficient roof water drainage – Quick Stream WAVIN drain hopper

This simple QS 75x75 drain hopper, made of polyethylene (PE), is a key element of the WAVIN Quick Stream system, designed for fast and efficient drainage of rainwater from 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 water drainage system.

Construction and application

The drain hopper combines the function of a simple connector and an element allowing for changing the direction of water flow. Made of durable high-density polyethylene (HDPE), it is resistant to corrosion and mechanical damage. Its round shape and welding spigots ensure tight and durable connections in the system. A length of 175 mm provides sufficient space for maneuvering during installation. The Quick Stream system utilizes the phenomenon of negative pressure, which allows for more efficient water drainage than in traditional installations.

Advantages and benefits

• Increased throughput: The Quick Stream system, and especially this drain hopper, allows for draining a larger amount of water using pipes with a smaller diameter – this saves material and costs.
• Strength and durability: High-density polyethylene (HDPE) provides resistance to weather conditions, corrosion and mechanical damage, guaranteeing a long service life of the installation.
• Tight connections: Welding spigots allow for making durable and tight connections, eliminating the risk of leaks.
• Simple installation: Quick Stream system elements are easy to install, which translates to shorter working time and lower installation costs.
• Standardized dimension ratio (SDR): An SDR value of 26 ensures compliance with industry standards and guarantees safety of use.
• Versatility: The drain hopper is compatible with other elements of the WAVIN Quick Stream system, allowing for the construction of complex drainage installations.
• Nominal pressure PN 4 bar: Ensures safe operation of the installation under typical operating conditions.
