Harcostar 227L Grey Water Butt Double Kit Outdoor Set

Twice the Storage. Smarter Rainwater Harvesting.

The Harcostar 227L Grey Water Butt Double Kit provides a complete dual-barrel rainwater harvesting system designed for larger gardens, higher water usage and households preparing for dry periods or hosepipe restrictions. With two 227 litre barrels connected by a long linking kit, this system delivers a combined 454 litre storage capacity while maintaining efficient overflow control.

Who This System Is For

Ideal for homeowners, gardeners, allotment holders and eco-conscious households looking to reduce mains water use and maximise rainwater collection from roof downpipes. Particularly suited to larger gardens, vegetable plots and areas with heavier rainfall.

How the Double System Works

Each barrel collects rainwater via its own universal rain trap diverter. The included long linking kit connects both barrels so water levels balance between them, allowing the system to operate as one combined 454 litre storage unit. Once full, excess rainwater continues flowing down the downpipe as normal.

Complete Kit – Everything Included

• 2 x 227 litre grey water butts
• 2 x spring-operated child-safe lids

• 2 x three-part raised stands
• 2 x Harcostar universal rain trap diverters

Benefits of the Raised Stands

Each barrel is elevated on a sturdy multi-part stand to improve gravity-fed water flow and make filling watering cans easier without bending. The raised design also improves tap clearance and overall stability.

Universal Downpipe Compatibility

The supplied rain trap diverters fit most standard plastic downpipes including:

• 68 mm round
• 80 mm round
• 100 mm round
• 65 mm square plastic downpipes

Not suitable for cast iron downpipes.

Durable UK Manufactured Construction

Manufactured in the United Kingdom from durable recycled and recyclable polyethylene plastic, the barrels are designed for year-round outdoor performance in changing weather conditions. The classic barrel shape offers generous storage capacity while fitting neatly against walls, fences or sheds.

When to Use a Double Water Butt System

This high-capacity system is particularly beneficial during summer watering periods, extended dry spells or hosepipe bans. The increased storage ensures more collected rainwater is available for lawns, plants, vegetable gardens and outdoor cleaning.
