Description

• Universal anti-backup roof drain is one of the best systems for connecting rainwater pipes and drains on flat roofs, gutters of multi-pitched roofs, and industrial buildings.
• It is particularly suitable for use with all kinds of APP or SBS modified bituminous membranes as well as liquid bitumen coatings.
• The drain is made from a special synthetic rubbers’ compound designed to score high flexibility and resistance to UV rays, ozone and other atmospheric and chemical agents.
• It can be used in a wide temperature range as it is extremely flexible at low temperatures and stable over time.
• It consists of a truncated body available in various diameters solidly attached to the meshed flange (5 mm x 5 mm). The stem piece of the unit has two or more strategically placed circular ribs which face outwards, which, when forced into the drain pipe prevent backing-up and form a perfect seal. The seal rings are compressed upwards when inserted into the drainpipe, achieving optimal sealing with any type of pipe.
• The passage of water vapor or backing up of liquids into the roof system and particularly into the insulation is thus eliminated.
• Available in diameters of 60 mm, 80 mm, 90 mm and 100 mm
