Marley Curve®

The Marley Curve® is a leaf diverter that combines sleek, sophisticated design with innovative filtering technology. Its unique screen design draws rainwater in while preventing leaves and other debris from entering into water tanks or stormwater systems.

Suitable for new or existing downpipes, the Marley Curve® has been designed in New Zealand to meet all rainfall conditions. Curve® helps to improve water quality and reduce system maintenance by delivering cleaner water to water tanks. If on stormwater, Curve® reduces the chance of drains blocking.
