How it works?

The EPAMS® system is a combination of cast iron pipes, fittings and accessories, jointed with PAM couplings able to withstand a negative pressure of -900 mbar.

The system is under French Technical Approval 5+14/14-2386 CSTB.

EPAMS® outlets are equipped with an anti-vortex mechanism that prevents air from entering the pipes at rainwater inlets. The absence of air then causes an acceleration of the flow by creating a negative pressure.

EPAMS ® design service

A siphonic roof drainage system is truly an "engineered system" which must be designed with careful and expert analysis. The pipework design is the key factor for performance and operational safety. PAM Building sales staff, trained in the EPAMS® system, first evaluate your roof drainage project. When feasibility is confirmed, a technical team designs both the technical study and network sizing using the dedicated EPAMS® software.

The system must always be properly balanced and the flow velocity controlled. To protect the lifespan of the EPAMS® siphonic systems, the PAM Building design maintains that the dynamic pressure within the system should never exceed 5 bar.

Trained staff specifically in charge of your design will handle your siphonic project until the work’s acceptance; each change to the plans results in the need for a new study. Before the acceptance of the work, PAM Building or a delegated third party checks on site that the installation fully complies with the last study isometric drawings; any modification to an EPAMS® pipework route at the installation stage requires further approval from PAM.

This thorough management of the EPAMS® projects – feasibility study, project follow-up and control after installation completion – ensures the EPAMS® system’s efficiency and provides the project manager with total peace of mind.
