The drain and siphon units shown here are excellent connections between the waterproofing materials and the down pipes themselves. They are made from IGOM EE thermoplastic rubber and are fitted with an
embossed flange to enhance adhesion with a torch-on membrane, but are also available for use with other types of waterproofing such as PP, PE, ECB or PVC where hot air welding is used.
They are fitted with an adjustable bellows system for use with various thicknesses of paving materials and are available with ABS, PP or stainless steel grilles.
The siphon type drains are fitted with a plug for easy cleaning of deposits and can either be welded or sleeve fitted to normal PE pipes. They are suitable for use on flat roofs, patios, bathrooms, garages, laundry rooms etc.
N.B. Siphon type drain units should not be used in areas where freezing is likely to occur.

Specification
Drain with horizontal discharge art. 147-148.
Suitable for use with HDPE discharge pipes having diameters of 90 mm. or 110 mm. weldable to a standard pipe fitting or PP curve with a seal ring. The flanges are made from ribbed IGOM.EE (thermoplastic rubber) to enhance adherence of the membrane.

Flange art. 147.1-148.1.
These flanges can be welded to HDPE bends or pipes to connect waterproofing materials, thus obtaining a solution giving continuity between horizontal and vertical drain pipes.
