Internal Drain 68mm Kit

Internal Drain 68mm Kit | EPDM Internal Roof Outlet

Controlled Internal Drainage Through the Roof Deck

The Internal Drain 68mm Kit creates a dedicated internal outlet that allows water to discharge from an EPDM roof directly into a rainwater downpipe. It forms a neat drainage point through the roof deck, helping prevent standing water and reducing stress on the surrounding membrane.

Reliable Seal for Long-Term Performance

Mechanically fixed and sealed using uncured EPDM flashing tape and primer, the drain sits flush and delivers a clean, watertight connection at the outlet point. A fitted leaf grate helps prevent debris entering the system, supporting consistent water flow and dependable performance over time. When used as part of a complete EPDM system, it supports a roof with a life expectancy of up to 50 years.

Installation Overview

Fix through the roof deck, dress the membrane over the flange, then seal using the supplied uncured flashing tape and primer to form a secure compression seal at the outlet.
