Description

Suitable for use with ClassicBond and ClassicBond Pro membranes. Universal antiback 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. 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.

Usage: Outlet for domestic type roofs with internal drains connecting to 68mm downpipe. The outlet is manufactured with a smooth flange allowing for greater bond strength to the EPDM detail than a
regular ridged outlet
