The Save the Rain Diverter captures water from your downspout and channels it into your barrel. The ideal condition for the diverter is when the barrel is placed in front of the downspout. During the water collection season the diverter stays open and diverts water into the barrel. When you put your barrel away for the winter you simply close the flap on the diverter and your downspout resumes its original function without having to reassemble it.
