OAYAYONI Rain Barrel Diverter Kit – Easy Downspout Connection + Hole Saw Set

Transform unused rainwater collection into an everyday ally with the OAYAYONI Rain Barrel Diverter Kit. This practical kit lets you connect a rain barrel to rectangular downspouts without dismantling your existing hardware, turning a simple plastic container into a functional water reservoir for your outdoor needs.

Designed for straightforward installation, the kit supports standard rectangular downspouts (2x3 and 3x4 inches) and feeds clean, chemical-free rainwater into your barrel. An overflow design helps manage flow when the barrel fills, reducing splashes and runoff and keeping your space tidy. The system is built to adapt to a variety of setups, with a flexible hose that stretches from 9.5 inches to 31 inches, making positioning comfortable in many corners of your yard or garden.

What you get — the Diverter, Fill Hose, Hose Seal, Winter Hole Cover, and two hole saws (2-1/8 and 1-1/2 inch), plus a sturdy flex hose included to connect to your rain barrel. This package provides all you need to start capturing rainwater from a rectangular downspout with minimal fuss and tooling.

Key benefits and considerations

• Easy to use — install without removing the downspout and connect quickly to your rain barrel, minimizing disruption to your outdoor space.
• Rainwater utilisation — capture chemical-free rainfall for plant irrigation and other non-potable tasks, helping you make use of natural resources.
• Overflow design — when the barrel nears capacity, water backs up into the downspout to help control flow and reduce runoff.
• Compatibility — fits standard rectangular downspouts (2x3 and 3x4 inches); not suitable for metal drums or circular downspouts.
• Flexibility — a length-adjustable hose supports diverse installation layouts and container placements.

How to install and use

• Position the diverter on your existing downspout without dismantling it.
• Use the included hole saws to create the feed path into your container, then seal connections to prevent leaks.
• Attach the fill hose to guide rainwater into the barrel and secure the winter hole cover when not in use.
• Test the setup with a light rainfall to observe flow and overflow behavior.

Real-life use ideas

• Water your garden or container plants with rainwater, reducing dependence on tap water.
• Use captured rain to flush outdoor cleaning tasks or to fill small irrigation systems around the yard.
• Pair with a rain barrel to create an accessible reservoir for seasonal rain events.
