Description
The Hargreaves Cast Iron Flat Back Heritage Hopper is a robust and classically styled rainwater collection unit, designed to channel water efficiently from gutter outlets into the downpipe system. With its traditional square shape and slightly larger capacity than the H0 model, the H1 hopper combines period aesthetics with modern reliability — perfect for heritage buildings, restoration projects, and high-end new builds.
Manufactured in the UK by Hargreaves Foundry, this hopper is made from premium cast iron for long-lasting performance and exceptional strength. The flat back design allows for a clean, flush wall fit, while the spacious interior ensures efficient water flow and reduced risk of overflow.
Available in four sizes to suit 65mm, 75mm, and 100mm round downpipes, and in a choice of primed (ready to paint) or factory-applied black gloss finishes, this versatile hopper offers a timeless look that complements both traditional and contemporary properties.
