Buying advice

When choosing a rain barrel diverter, consider your downspout shape (round or rectangular) and size. Look for features like built-in overflow, mesh filters to keep out leaves, and durable materials that can withstand weather. If you want flexibility, a diverter with a flow control valve or multiple adapters is ideal. Ensure the kit includes all necessary fittings for your rain barrel type.
