    Installation

    • Specify sufficient fall/s to meet BS6229. Rainwater outlets should always be freely accessible for maintenance
    • It is recommended that roofs with interior drainage must have at least one emergency overflow or several exterior downpipes
    • Position rainwater outlets at the lowest point of a roof. The position and number of outlet pipes should be calculated using current regulations and best practice to ensure that surface water can drain away effectively. Maintain sufficient distance from rising building componentsand joints.
    • Rainwater outlets and emergency overflows should be fixed to the substructure of the roof. If the roof surfaces are divided into sections (e.g. fire compartments) then these areas must also be drained individually
    • Rainwater outlet flanges should be compatible with the roof membrane to ensure a watertight seal is made. Flanges should be below the roof membranes finished level to ensure that water does not puddle around the outlet. A two-piece outlet must be used to connect to the vapourbarrier in a ventilated roof

    Area of application

    • Single-piece flat roof rainwater outlets are suitable for ventilated flat roofs and two-piece flat roof rainwater outlets are suitable for unventilated flat roofs
