Troubleshooting
Water leaking from the connection point

Difficulty pushing the downpipe into the socket
Apply a small amount of silicone lubricant to the seal and ensure the downpipe end is deburred.

Setup, Compatibility & Care
Installation should be performed on a level fascia board. Ensure the gutter is cut cleanly to allow the retained seals to seat correctly. The component is designed for the 61mm square downpipe system. Avoid using petroleum-based lubricants on the seals, as these can degrade the rubber; use a dedicated silicone-based lubricant if necessary. To maintain the system, periodically clear debris from the gutter to prevent blockages that could overwhelm the outlet capacity. During cleaning, avoid using abrasive materials that could scratch the finish, and regularly check that the gutter clips are holding the outlet securely against the fascia.
