The Rain Wizard Connector Kit is your tool for expanding the capacity of your Rain Wizard rain barrels. This kit is ideal for conditions that don't allow for a single, large barrel to sit against the house. Simply connect each end of the hose to the next barrel per the instructions. When the primary barrel is full, it will overflow into the next rain barrel. Setup can be done quickly and just requires a screwdriver for the clamps and a drill with a 1/4 in.-3/8 in. bit. When positioning the rain barrels be sure to have the primary barrel (the one at the downspout) level if not higher than the secondary barrels. This ensures that water will flow out through the connector hose and into the second barrel. The higher the first barrel than the second, the more water pressure into the second barrel and reduced waste in overflow.
