Full details

This pre-formed component significantly streamlines the installation process for domestic and small commercial projects by ensuring a secure transition. However, users should note that successful installation requires specific EPDM-compatible contact adhesives and primers to ensure a watertight bond with the surrounding roof membrane.

How often should I inspect the outlet?

Is the material UV resistant?

Pros and Cons

Pros

  • Reduces installation time for drainage connections
  • High-performance EPDM material ensures long-term durability
  • Prevents common leak paths around internal pipe penetrations
  • Compatible with standard domestic 68mm rainwater piping

Cons

  • Requires specific primers for a secure bond
  • Not suitable for non-EPDM membrane systems
  • Requires precise membrane cutting for a perfect fit

Setup, Compatibility & Care

Installation should only be performed on a clean, dry surface. Ensure the 68mm pipe is securely fixed to the building structure before fitting the outlet. Compatibility is limited to standard 68mm rainwater systems; verify your pipe diameter before installation. For care, inspect the outlet seal annually for any signs of membrane lifting or debris buildup. Clear away leaves and moss from the immediate area surrounding the outlet to prevent blockages that could lead to water backup, which may stress the connection over time.
