OAYAYONI Rain Barrel Diverter Kit for 2x3 & 3x4 Rectangular Downspouts — Hole Saw Set, Easy Install

The OAYAYONI Rain Barrel Diverter Kit converts a standard rectangular downspout into a working rainwater collection system quickly and without removing the downspout.

Capture and reuse roof runoff with a compact kit designed for 2x3 and 3x4 inch rectangular downspouts. The kit includes a diverter body, flexible fill hose, seals, a winter plug, and two hole saw sizes so you can fit the diverter to common plastic containers. Installation requires no downspout removal, and the unit routes overflow back into the downspout when your barrel fills.

How do I install this diverter without taking down the downspout?

Installation is designed to be simple: drill a hole in the downspout using one of the included hole saws, attach the diverter with the supplied seal, and run the flexible hose into your barrel. No cutting out a downspout section or complex brackets are necessary, so most DIYers can finish the job in under an hour.

• Includes 2-1/8" and 1-1/2" hole saws for precise entry points.
• Hose seal and winter hole cover included to prevent leaks and freezing issues.
• Strong flex hose stretches from 9.5" to 31" to reach various barrel positions.

What types of containers and downspouts will this diverter work with?

The diverter is built for standard rectangular downspouts sized 2x3" and 3x4" and converts most plastic containers into rain barrels. It is not intended for round metal drums or circular downspouts, and capture efficiency can be slightly lower on the larger 3x4" profiles.

• Best fit: standard plastic rain barrels and recycled plastic containers.
• Compatible downspouts: rectangular 2x3" and 3x4" only.
• Not suitable for circular or metal-only downspout systems.

How does the overflow and winter protection work?

The diverter routes water into your barrel until the barrel’s level rises above the inlet; once full, the system allows water to back up into the downspout and continue to your existing drainage. For freezing months the kit provides a winter hole cover so you can close the inlet and avoid ice blockages in the diverter or hose.

• Overflow returns to downspout to keep gutters functioning when barrel is full.
• Winter hole cover included to close the inlet during freeze/thaw cycles.
• Simple hose and seal design reduces chances of leaks and pests.

What tools or materials will I need besides this kit?

You’ll need a power drill to use the included hole saws and possibly a screwdriver to finish mounting. Because the kit contains the hose, seals, and winter plug, no extra parts are usually needed—only basic household tools and a suitable plastic container to receive the water.

• Power drill compatible with the provided hole saws.
• Optional screwdriver or wrench for final adjustments.
• Clear space to position barrel within 9.5"–31" of the downspout.

Who is this for: The OAYAYONI Rain Barrel Diverter Kit is ideal for homeowners, renters with permission, gardeners, and anyone wanting an affordable, low-effort way to harvest rooftop runoff into a plastic barrel for landscape watering and non-potable outdoor uses. It suits DIYers who prefer a quick install without dismantling the gutter system and those looking to reduce municipal water usage in their garden.
