1. A device to prevent the flow of water from a fill valve having a float within a tank of a toilet having a water supply tube due to a failure of a main flop, a chain, or a flush lever, the device comprising:
a housing, the housing having a size to at least completely surround the float and
a portion of the fill valve to generally encapsulate water within an interior space, the housing comprising:
a bottom having a central aperture and a bore;
a plurality of sidewalls coupled to the bottom and extending a height opposite the bottom;
an open top portion, the open top portion culminating at an end of the height of the plurality of sidewalls and defining the interior space;

a secondary flop, the secondary flop positioned on the bottom of the housing and sized for receipt in and for sealing the bore;
a secondary chain, the secondary chain coupled to the secondary flop and the flush lever, wherein manipulation of the flush lever is translated through the secondary chain to the secondary flop for opening and sealing the bore; and
a secondary water supply tube, the secondary water supply tube coupled to the water supply tube and affixed adjacent to the open top portion, wherein water from the water supply tube is directed into the secondary water supply and into the interior of the housing during filling of the toilet tank, wherein the central aperture is sized to receive the fill valve and allow a watertight coupling between the housing and the fill valve.
