The handy Diverter Pro makes collecting rainwater a breeze. Its ingenious design allows water to flow freely into catching systems without debris like leaves and twigs that might otherwise travel through a downspout, and efficiently catches more water during heavy downpours. The diverter fits standard downspouts (2-inch-by-3-inch and 3-inch-by-4-inch), and includes a connector hose, connector, filter and an easy-to-follow, step-by-step installation guide. It also features a dual output that allows a rain barrel to be placed on both sides of the downspout. Easy winterization and filter upkeep are also pluses. It is made of recyclable polypropylene.
