The Rain Wizard Flex Kit is the first diverter system that will work with ANY rain barrel and virtually every downspout. The design is simple and all of the tools are included. With the Flex Kit, you don't have to worry about tearing your gutter off the house and messing with countless screws. And you can keep your gutter completely intact which is ideal in case you decide to move your rain barrel to a different location or just store it for the season. Installation is quick and easy. On the downspout, just drill a hole with the proper included hole saw. Then insert the rubber rain catch. This rain catch is specially designed to collect water as it runs down the walls of your downspout while filtering out leafy debris. Then drill a hole in your rain barrel at the same level and insert the flanged rubber receiver. Finally, you simply connect the diverter and receiver with the included flexible tubing and you're done.
Minimal modification to your downspout
Keep using downspout regularly even if you move your rain barrel
