  • Check valve for downspouts
    Patent number: 10837177
    Abstract: Methods, systems and devices for a check valve for deterring intrusion into downspouts include a body member having at least a first orifice and are configured to mount on a downspout, where the downspout is adapted to promote fluid flow in a single direction. Pivotably mounted on the body members are various valve members. The mounting arrangement can provide a closed position that substantially occludes the first orifice and a range of open positions when the valve member is pivoted with respect to the body member to open in the flow direction. In addition, at least one additional orifice can be provided in either the body member or the valve member to permit fluid flow irrespective of the position of the valve member.
