Complete Ready-to-Install Kit

This system includes the 350 litre Magnum rain barrel, a spring-operated child-safe locking lid, hose connector tap positioned approximately 340mm above ground level for easier watering can access, and the award-winning Gutter Mate Rain Saver Diverter & Filter. All components are designed to work together for efficient and controlled rainwater collection.

Award-Winning Gutter Mate Diverter & Filter

The UK best-selling Gutter Mate diverter channels rainwater directly from your downpipe into the tank while filtering out leaves and debris. Its patented automatic overflow system redirects excess water back into the downpipe once the tank reaches full capacity, helping prevent overflow and reducing maintenance.

Safety and Practical Design

The spring-operated child-safe lid helps improve household safety while keeping stored rainwater protected from debris. The raised tap height improves access and usability for watering cans and hose connection.

Durable Outdoor Construction

Manufactured from UV stabilised recycled polyethylene plastic, the 350L Magnum is built for year-round outdoor use in typical UK weather conditions when positioned on firm, level ground.
