ClassicBond Universal Anti Back Up Roof Drain 68mm

Universal anti-back up drain is one of the best means of connecting roof systems with 68mm rainwater pipes (standard domestic UK size) on flat roofs, gutters, domestic & commercial buildings. This has a high resistance to UV light, ozone, movement and cracking.

Features:

• The stem piece of the unit has two or more circular ribs which face outwards and 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.
• The outlet is manufactured with a smooth flange allowing for greater bond strength to the EPDM detail than a regular ridged outlet.
• Square, smooth flange 285x285mm for adhering membrane and PS Tape to.
• 185mm outlet pipe with round flange, which when pushed solidly home into pipe ensures there is no backing up of water between the outlet and the inside of the pipe.
• Internal drain diameter 55mm.
