The Brett Martin 65mm Square to Round Downpipe Adaptor is designed for homeowners and contractors seeking a seamless transition between square-profile downpipes and round drainage systems during property renovations or repairs. It offers the benefit of simplified integration between differing guttering styles while maintaining robust drainage performance, though users should ensure they are matching the precise 65mm diameter and square profile dimensions to avoid leaks.

This adaptor is specifically designed for the Brett Martin square-style rainwater system.
No, it features integral fixing clips and external wings for a secure mechanical fit.
The component is weather-resistant; simply wipe down with a damp cloth during routine cleaning.
While it offers 20% higher flow, it is primarily rated for domestic roof drainage applications.
It is tested for accelerated ageing in accordance with BS EN 607: 1995.
Check that the pipes are fully seated within the adaptor and ensure the seals have not been displaced during installation.
Ensure the pipe end is free of burrs and that the diameter is exactly 65mm; use a small amount of silicone lubricant if the fit is too tight.
To install, ensure the downpipe is cut cleanly to length before sliding the adaptor into place. Utilize the external fixing wings to secure the component to the wall using standard fasteners. The system is designed to be low-maintenance, but you should periodically inspect the joint to ensure no debris or organic matter has caused a blockage. During annual gutter cleaning, flush the adaptor with water to confirm the transition remains clear and the seals are intact. This product is strictly compatible with 65mm square rainwater systems manufactured by Brett Martin.
