Lindab Magestic Galvanised 100mm Steel Downpipe Adjustable Rainwater Diverter

Harvest rainwater without compromising drainage using the Lindab Magestic Galvanised 100mm Steel Downpipe Adjustable Rainwater Diverter. Fitted inline on a 100 mm stack, it lets you direct flow to a water butt, barrel or storage tank during wet spells and send excess straight to the gulley when capacity is reached—ideal for sustainable retrofits and new builds alike. The simple adjustable mechanism switches and throttles flow without tools, while the smooth internal bore helps maintain performance in heavy rain. Manufactured from Lindab’s Magestic galvanised steel, the zinc–magnesium enhanced coating stabilises the surface and protects zinc’s naturally porous structure for excellent resistance to red rust and white staining, even on exposed or coastal sites. Supplied unpainted, it will weather to a smart dark-grey patina that pairs with brick, render and contemporary cladding. Combine with matching Magestic brackets, pipes and shoes to complete a durable, recyclable rainwater system.
