Abstract: The Downspout Debris Collector is a water filter (D) located approximately four feet above the ground inside a fifteen inch section of downspout. (A) It is inserted into an eleven inch opening cut into an existing downspout. This filter is a ¼ inch holed wire screen (B) riveted horizontally inside five inches from the bottom of the fifteen inch section. (C) Debris collectors in roof gutters are strainers, called “birdcages” that are located in the gutters where the gutters are jointed with the downspouts. This strainer is accessible only at roof height and cleaning it requires considerable effort. The Downspout Debris Collector being four feet from the ground is easily accessed. To clean it raise it until the bottom portion is free, remove it, turn it upside down, empty the debris and then replace it. This unit ELIMINATES debris from clogging underground pipes saving building foundations and money.
