Product Information

Full details

The Lindab Drain Connector (MRTBK) is designed for contractors and homeowners looking to bridge the gap between steel downpipes and non-standard ground pipe dimensions. Its primary benefit is providing a secure, leak-proof transition for drainage systems that would otherwise require custom fabrication, though users should verify the exact diameter of their existing ground pipe to ensure a tight fit before installation.

FAQs

Is this connector suitable for underground use?

Yes, it is designed for connecting to ground pipes and is built to resist environmental wear.

Does it come in other colors?

The model MRTBK is specifically supplied in black.

Can I use this with plastic downpipes?

This connector is optimized for steel downpipes; compatibility with plastic pipe diameters should be verified before purchase.

Do I need to glue the connection?

Mechanical friction is usually sufficient, but a small amount of sealant can be used if extra security is desired for non-standard installations.

Will sunlight cause the plastic to become brittle?

No, the material is specifically engineered to be UV-resistant to prevent brittleness over time.

Troubleshooting

Connector feels loose on the pipe

Verify the diameter of the ground pipe and use a bead of appropriate outdoor-rated sealant if the pipe is on the smaller end of the tolerance range.

Difficult to push onto the downpipe

Apply a small amount of silicone lubricant to the exterior of the downpipe to allow the connector to slide into place more easily.

Pros and Cons

Pros

  • High resistance to UV and weather damage
  • Simplifies installation for non-standard pipe sizes
  • Compatible with HD polyethylene filters
  • Provides a long-lasting, secure connection

Cons

  • Requires verification of specific ground pipe diameters
  • Not intended for high-pressure irrigation lines
  • Limited to specific steel downpipe configurations

Setup, Compatibility & Care

To install, ensure the steel downpipe is cut cleanly and free of burrs. Slide the connector over the downpipe and insert the other end into the target ground pipe. If the fit is tight, ensure the ground pipe is clear of debris to prevent misalignment. Regarding compatibility, this unit is designed for standard steel downpipe systems integrating with non-standard ground ports. Care is minimal: inspect the joint annually during gutter cleaning to ensure it remains seated correctly. The material does not require painting or specialized treatments to withstand outdoor conditions.
