List of featured suppliers of ROOF OUTLETS Rainwater Anti Vortex Antivortex AV on Building Products Index
Roof outlets are features that are designed to allow rainwater to drain off a roof and into a suitable drainage system. These outlets often include an anti-vortex mechanism to prevent water from swirling around as it drains, which can cause blockages or damage to the building's drainage pipes. These anti-vortex devices are sometimes abbreviated as "av" for short. All in all, roof outlets with anti-vortex systems are essential components for keeping a building's roof and drainage system in good working condition.
