When rain falls onto a flat roof, large volumes of water can collect rapidly. ACO offers functional solutions which are specially designed for flat roof areas and which ensure the water is drained effectively. For bigger surfaces, siphonic systems can be installed.

• Jet drains made of stainless steel or cast iron
• Large roofs, per drain 150 m2
• Adequate height difference of 4.2 m between the roof and the buried pipes
• Situation with only limited space beneath the ceiling (no room for installing inclined pipes)
• Long collection pipes
