Oatey’s Mystic Rainwater Collection System captures water from downspouts and redirects it through a tube into a rain barrel, which is not included. (Sealed rain barrels work best; common vented ones may overflow.) Leaves and sediment simply pass through the device, which can be attached to a downspout without removing the spout from the wall. The diverter costs $20. Oatey, 800/321-9532, oateymystic.com
