How this avoids air entrapment and only allow water to enter? and secondly that small tube water movement is by capillarity. Does this 4inch or 2 inch pipe works on the same principle like smaller tube. Thank you

Hi Pangestu, siphonic technology is better suited to large, flat roof construction like warehouses, big box stores and similar construction.

Is it beneficial to apply this to an ordinary house?
