Siphonic Rainplus 110mm Outlet

Siphonic Rainplus Outlet

The Rainplus system is used to drain rainwater from the roofs of medium and large buildings. This system takes advantage of the building’s height combined with the special design of the collection piping system, which creates negative pressure as the main force driving high-speed flow. It allows water to flow into any part of the building, facilitating the installation of modern rainwater collection systems and easy layout planning.

This system includes special siphonic funnels, different from traditional rainwater collector funnels. The device consists of a pipe body, a flat surface, and a spiral shield made of aluminum coated with a special UV-resistant plastic, a polypropylene leaf guard capable of withstanding at least 200 kg of load, and a connecting pipe to link with the HDPE Valsir pipe featuring safety equipment and a double sealing ring.

The siphonic funnels are built and tested according to ASME A112.6.9 and EN 1253 standards and must be connected to Valsir high-density polyethylene HDPE pipes, designed to operate under negative pressure, with high flow rates and completely full to prevent air intrusion when the design rainfall intensity is reached.

The funnels are equipped with accessories that allow installation on bitumen-sealed roofs or other plastic materials, or in rainwater drainage systems or collection channels.

The system is equipped with heavy-duty galvanized steel support hooks and is specially designed for tight mounting, allowing them to be locked onto U-shaped support bars.

• Structure of the Siphonic Rainplus Roof Water Collector Funnel: The siphonic funnel is composed of a pipe body, a compression surface for anchoring, and a vortex shield made of aluminum coated with a special protective paint. It also includes a polypropylene leaf guard that can withstand a load of at least 200 kg and a plug to connect with the HDPE Valsir pipe, which features a safety device and two sealing rings.

• Stainless Steel Plate: A stainless steel plate must be used for installation in the rainwater pipe. The aluminum compression surface compresses the stainless steel plate on both sides, where two rubber pieces ensure water tightness. The stainless steel plate must be welded or firmly anchored into the rainwater pipe using appropriate mastic to ensure water tightness.

• Galvanized Steel Plate: A galvanized steel plate must be used when applying waterproof membranes (such as TPO, PVC, bitumen) on the roof. The aluminum compression surface compresses the membrane onto the steel plate, and a rubber sealing ring ensures water tightness.

• Stainless Steel Bolts: Stainless steel bolts are used to ensure the water tightness of the roof/rainwater pipe structure.

• Pipe Testing: The discharge pipes are tested by an accredited independent testing institute, LGA-TUV in Würzburg (Germany), to meet performance requirements for siphonic drainage systems in accordance with EN 12056-3, EN 1253, and ASME A112.6.9.

• Accessories: Thermo-Kit for de-icing, Overflow-Kit for emergency backup siphonic systems.

• Installation and Maintenance: Must follow the relevant Valsir Rainplus guidelines.
