My fiance and I have two barrels that we recently purchased for rain collection from our downspout in the back of our house. I would like to find a way to connect the two barrels together (so we don't have to even try and move a full barrel) so that when one is full the rain will then go into the next barrel. Any ideas, suggestions, comments are welcome! We have two 55 gallon plastic barrels we want to use. They each have spigot at the bottom so we can hook up a hose when needed.
