EPAMS Siphonic System

Architectural design and roof sizes of certain modern buildings can often make the installation of conventional rainwater drainage a difficult task, and with increasing rainfall intensity the need to evacuate rainwater from the roof at higher speeds is becoming more important.
The EPAMS cast iron rainwater system from Saint-Gobain PAM UK provides the perfect siphonic solution, as it requires fewer vertical stacks and can use smaller diameter outlets and pipework horizontally that can run parallel to roof saving on installation and space.

EPAMS principle of siphonic drainage
The EPAMS range is the ideal choice for syphonic rainwater drainage, with its strong, high capacity outlets and the peace of mind of cast iron pipes and fittings. EPAMS products are non-combustible, quieter than other materials, have a longer life expectancy and a mechanical resistance allowing them to easily withstand both positive and negative pressures. Saint-Gobain PAM UK is a member of the Syphonic Rainwater Drainage Association (SRDA).
