Abstract
Included in this disclosure is a downspout drain filter for rain gutter downspouts. The downspout drain filer comprises elongated housing having an axis, a top portion, and a bottom portion. A transition portion connects the top portion to the bottom portion. The top portion includes an intake opening, a top portion perimeter, a debris opening, a filter attachment location, and a downspout attachment location. The downspout attachment location includes a flexible collar that defines a downspout attachment location perimeter that is less than the top portion perimeter. The bottom portion includes a flexible collapsible body that extends from the transition portion. A connection end is positioned opposite the transition portion as a part of the bottom portion. A filter is positioned in the top portion to direct debris out the debris opening and to permit liquid to pass to the bottom portion.
