Increase your rain water storage capacity with this efficient barrel link kit. The RainReserve Daisy Chain Kit makes it possible for you to add an additional rain barrel in series to your existing RainReserve tandem system. Designed for use with a single RainReserve Diverter System, this kit securely connects one rain barrel to the next. Once the first reservoir fills, the next is automatically filled. The kit includes everything you need to make any sealed tank or barrel a rain reservoir: a high-flow spigot, quick-assembly barrel seals, and a corn plastic sticker that reads "Do Not Drink" to discourage drinking the water.
