Claim Text:
1. A foot valve apparatus, comprising: a) a valve housing having an upper flange, a lower flange and a cylindrical section, said valve housing having an exterior and an interior with a flow bore having a central axis; b) the upper flange having a periphery, an upper larger diameter central opening and a plurality of circumferentially spaced smaller diameter upper openings, each smaller diameter upper opening being spaced in between the periphery and the upper larger diameter opening; c) the lower flange having a periphery, a lower larger diameter central opening and a plurality of circumferentially spaced smaller diameter lower openings, each smaller diameter lower opening spaced in between the periphery and the lower larger diameter opening; d) the cylindrical section having upper and lower end portions, wherein the upper end portion contacts the upper flange in between the upper larger diameter central opening and the plurality of circumferentially spaced smaller diameter upper openings; e) wherein the lower end portion contacts the lower flange in between the lower larger diameter central opening and the plurality of circumferentially spaced smaller diameter lower openings; f) a valving member pivotally mounted to the valve housing with a pivotal connection that is next to the lower end portion of the cylindrical section and movable between open flow and closed flow positions, wherein the lower flange provides a valve seat that is spaced inwardly of said cylindrical section, said valving member engaging said seat in the closed flow position; g) a cable connected to the valving member opposite the pivotal connection, the cable extending diagonally with respect to said bore central axis and forming an acute angle therewith; h) a cable opening through the upper flange at a first position vertically above the pivotal connection; I) wherein said cable extends from the first position to a second position, passing through the cable opening nearer said second position and spaced away from said first position; j) a cable handle on the cable at the second position that enables a user to grasp the handle and pull the cable; k) wherein the second position is on the exterior of said housing; and l) fasteners that connect the upper and lower flanges together, each fastener spanning between a said smaller diameter upper opening and a said smaller diameter lower opening.
