INSTALLATION
Marley downpipe systems are intuitively designed as a modular system, making repair and replacement much simpler. However, there is a technical element to installing Marley downpipes so if you are unsure, Marley recommends you seek advice from a trade professional.

Note: Rectangular downpipes should not be used in wall or ceiling cavities, in a horizontal application, in wet syphon systems, or when subjected to pressure. E.g. connected to water tanks.
