The Mystic rainwater collection system is used to recycle rainwater by directing rainwater from downspouts into collection barrels (not included) for re-use in lawn and garden watering. The Mystic is easily installed and will fit on a standard 2" x 3" residential downspout. Step by step instructions are included along with a 4' high-flow hose to connect the diverter to the collection container. The 2-piece design is made of durable, UV-resistant material and can be painted to match the downspout color. Environmentally friendly.
