PVC (siphon) rain drainage system and its advantages.

​

Siphonic drainage allows you to drain rainwater quickly, reliably and inexpensively from large roofs, optimally fitting the system into the building's architecture and minimising installation costs. It is a practical, fast, and cost-effective high-quality solution designed primarily to remove rain from the roofs of public and industrial buildings which are subject to special architectural and structural requirements.

 

The principle of this system is based on the negative vacuum pressure due to the difference in height between the output and the inlet. There are several advantages over the traditional system which make it cost effective and faster to install the system itself and even increase the efficiency of rain removal:

​

​

A small diameter pipeline that improves the appearance of the system and enables easy concealment of the entire installation.

​

​

For the designer - greater freedom in realising their ideas, better utilisation of the interior space of the building.

​

 

To the contractor - lower labour costs, quick and easy installation, reduced volumes of excavation work.

​

​

For the investor – faster payback.​
