Elements Wavin Quick Stream rainwater system are made of high-density polyethylene (HDPE). This material differs the higher shock resistance both at low and at high temperatures. In addition this material differs abrasion resistance and chemical resistance. Wavin Quick Stream rainwater system also is resistant to effects of ultraviolet light that is why it is allowed to install outdoors.
Elements of Wavin Quick Stream System:
Roof outlets are made of plastic and metal with diameters from 40 to 125 mm;
Fastening elements for Wavin Quick Stream system are used for installation of rainwater system. They include:
Screw nuts and bolts;
Clips for hanger;
Rail connectors etc.
Wavin Quick Stream rainwater system works on gravity vacuum principle that is creation of low pressure under the force of gravity water. Under normal rainfall Wavin Quick Stream system works like a traditional gravity system. If rainfall grows, risers will fill out with water causing Wavin Quick Stream rainwater system will go into pressure mode. In the riser discharge occurs and it carries away water from pipe. High flow speed and resulting discharge increased performance of Wavin Quick Stream rainwater system, with that diameters of Quick Stream pipes are reduced in comparison with free-flow rainwater systems.
The main advantages of Wavin Quick Stream rainwater system:
Savings at the expense less roof outlets, as well as reducing diameters of pipes;
Installation is possible without deviation of horizontal collector under the roof of building;
Minimum volume of excavation;
Air does not get into system through the roof outlet.
