The Lindab Intermediate Downpipe is designed for professional contractors and homeowners who need a durable, aesthetic solution for misaligned gutter outlets and ground drains. Its primary benefit is the ability to create offsets or swan necks, ensuring proper water drainage even when building geometry is complex. A notable caveat for users is that the galvanized steel system requires precise measurements before cutting, as it is a permanent installation compared to temporary plastic alternatives.

Yes, the galvanized steel surface can be painted, but it is recommended to use a primer compatible with galvanized metal to ensure proper adhesion.
The Lindab Rainline system is engineered to work as a complete integrated system; it is not guaranteed to be compatible with other manufacturer's guttering components.
Basic tools such as a hacksaw, measuring tape, and a screwdriver for fixing brackets are sufficient.
The 275g zinc coating provides excellent corrosion resistance, making it suitable for most environments, though heavy salt spray may require more frequent rinsing.
This specific model has a diameter of 120mm.
No, wall fixings and brackets for the downpipe must be purchased separately.
Check that the pipe is fully inserted into the bead and ensure no debris is stuck in the connection area.
Small areas of surface rust are typically part of the self-healing process; do not attempt to sand them, as they will stabilize over time.
Verify that your bends are set at the correct angles; the Lindab Rainline system is designed for a tight fit and may require slight pressure to align perfectly.
Installation of the Lindab system is straightforward, utilizing a 'push-fit' mechanism that relies on precision engineering. Ensure all connections are fully seated to maintain water-tight integrity. When cutting the 1m length to fit, use a fine-tooth hacksaw or nibbler to avoid heat damage to the coating. Avoid using angle grinders, as high heat can damage the protective zinc layer. For maintenance, the system is largely self-cleaning; simply rinse with water periodically to remove debris. If the surface is heavily stained, a mild soapy solution is sufficient. Do not use abrasive scouring pads as they may compromise the long-term self-healing capacity of the steel.
