For many years, architects and designers have been concerned with rainwater not effectively drained on balconies whenever there is a heavy rainfall. This is especially noticeable for high-rise buildings. Commercial pipe junctions have not been able to prevent back-flow of rainwater while being drained.

Fast Flow has now revolutionized the industry with this exciting patented device that solves the problem. psVent™ is an anti-backflow junction, specially designed for terrace and balcony. Since its launch in 2009, psVent™ is now widely accepted and the preferred choice for architects and interior designers to be used in their buildings.
