Extended Product Information

FAQs

Does the black finish fade over time?

The high-quality coating is designed to maintain its color and integrity, supported by a 15-year warranty on the coating finish.

Can I use this with plastic downpipes?

No, this connector is specifically engineered for the Lindab Rainline steel system and is not compatible with standard plastic PVC pipe dimensions.

How often does it need to be painted?

Lindab steel is low-maintenance and does not require painting; the galvanized finish is designed to be highly durable as is.

Is it susceptible to rust?

The steel is galvanized with a heavy zinc coating that protects against rust, even if the surface is scratched.

What is the expected life of the connector?

With proper installation, the product has a design life expectancy of over 70 years.

Is this suitable for DIY installation?

While it can be handled by DIYers, it is recommended to have experience with metalwork or to consult a professional to ensure a secure, leak-free connection.

Troubleshooting

Connector feels loose on the pipe

Verify the pipe is exactly 120mm and not deformed. Ensure it is fully seated to the central stop point inside the connector.

Visible surface scratch after installation

The 275g/m2 zinc coating is self-healing and will prevent rust on its own; no secondary painting or sealing is typically required.

Water weeping at the joint

Check that the pipe is cut perfectly square and has no burrs. Re-seat the connector to ensure a flush, even fit around the circumference.

Pros and Cons

Pros

  • Resistant to cracking, splitting, and leaking compared to plastic
  • Self-healing coating protects against surface scratches
  • Extremely long service life of over 70 years
  • Minimal maintenance required for long-term reliability
  • Vandal-resistant and robust for high-traffic areas

Cons

  • Requires precise 120mm sizing for a proper fit
  • May be more expensive upfront than standard plastic connectors
  • Requires professional installation for optimal sealing
  • Less flexibility during assembly compared to PVC components

Setup, Compatibility & Care

To install, ensure the downpipe ends are cut squarely. The connector can be positioned to fit either inside or outside the pipe diameter depending on your specific drainage flow requirements. When handling the steel components, wear gloves to prevent sharp edges from causing injury.

Care Instructions:

  • Routine Inspection: Check joints annually for any debris accumulation.
  • Cleaning: Occasional rinsing with water and a soft brush is sufficient to remove dirt or environmental buildup.
  • Compatibility: This 120mm connector is specifically compatible with the Lindab Rainline steel range. Mixing with non-compatible materials, such as copper or aluminum, should be avoided to prevent galvanic corrosion.
