TOP-PIPE HDPE provides an efficient and reliable solution for rainwater drainage from rooftops of buildings through the use of siphonic drainage principles. Traditional gravity roof drainage is fast-becoming an out-of-date technology in the construction industry. Today, many large industrial, commercial and retail buildings are making the switch to siphonic rainwater drainage. And residential buildings are beginning to follow suit.
Compared to the inefficient traditional gravity roof drainage systems, where water simply runs off into downward-sloping pipes, TOP-PIPE Siphonic Drainage Systems quickly fill up and suck or siphon the rainwater into the drain using the resultant negative pressure. The TOP PIPE roof outlets also prevent blockage so that air is not drawn into the systems to ensure reliable and efficient performance.
