When positioned within a rain gutter, rainwater flowing along the gutter is directed into and along water channels formed by the projections. An end of the apparatus is bent so as to extend a short distance into the downspout associated with the gutter thereby ensuring uninterrupted flow of rainwater therein. The covering material prevents the intrusion of leaves and other debris from entering the water channels so as to ensure clog free flow of rain water.Field of SearchCOVER WITH SURFACE WATER RECEIVER AT EAVE OR VALLEYWith separator; e.g., strainer With additional subsurface liquid receiver Inwardly of edge With downspout With drain or vent exterior to foundation perimeter At upper edge of filtrate receiver Medium within foraminous supporting container or sheath Flume stream type | |
