EPDM Internal Drain
The Internal Outlet drain is one of the best ways of connecting to a 68mm/100mm/110mm rainwater pipe (standard domestic UK size) on flat roofs, gutters, domestic & commercial buildings. They have a high resistance to UV light, ozone, movement and cracking.
The stem piece of the unit has two or more 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 and thanks to this pressure fit they guarantee optimal seal within the pipe.
The passage of water vapour or backing up of liquids into the roof system and particularly into the insulation is thus eliminated.
