Kompact Balcony Outlets Specifications 

Caroflow Kompact Balcony Outlets are available in either LM6 Aluminium Silicon casting alloy to BS EN 1706:2010 for most roof finishes or in leaded gunmetal to BS EN 1982:2008 for use with lead or copper-clad roofs or for connection to copper pipework. 
Offering all the benefits of the standard Caroflow Balcony Outlet, the Kompact Balcony Outlet is sized to allow easier and less-destructive installation for refurbishment and new balcony scenarios, whilst still allowing various sizes of pipework to drain into the outlet from upper levels. 
Our Kompact Balcony outlets are available in two sizes; 50mm and 75mm. 
The codes and dimensions of each of our Kompact Balcony Outlets is as follows; 
50mm Kompact Balcony Outlet

Drainage Areas & Flow Rates for Kompact Balcony Outlets 

BS EN 12056-3:2000 (Gravity drainage systems inside buildings – Part 3: Roof drainage, layout and calculation) now specifically limits the drainage capacity that can be used to calculate areas to be drained, so as to prevent siphonic action that may damage internal pipework. 
Previous physical testing of all our outlets has shown that the rates and areas (see adjacent table) are lower than results that have been seen from this actual testing. 
All rates are assuming that the outlet grate is free and clear of any debris/blockages 
Results are based on a rainfall intensity of 75mm per hour and a 35mm head of water adjacent to the outlet (45mm head for 160mm outlets as per EN 1253-2:2015). 
The flow rates shown should be used as a guide only. Each drainage area will have individual features that may influence overall flow characteristics.
