System Information

Siphonic versus traditional gravity-fed roof drainage

Smaller pipe dimensions, fewer roof outlets and downpipes, and shorter total pipe lengths all reduce installation costs. Because lateral pipes need no gradient, you maximize the use of building height too.


Wavin QuickStream has evolved over 30 years of successful projects. Our design software has rigorous safety checks built in, therefore we only release safe designs. The bracketing system is unaffected by pipe elongation resulting from temperature change. Special inspection chambers allow ventilation and overflow, preventing water accumulating on the roof.

System design

Wavin's design software optimizes system design for performance, safety and reliability. We design your QuickStream system according to the specific characteristics of your building. QuickStream also connects seamlessly with our complete range of below-ground components.


The Wavin bracketing system for horizontal pipe-work makes installation fast, easy and safe. We’ve made installing metal roof outlets trouble-free with a robust design which minimizes the number of parts.
