Claim 5:
6. A redundant system in the form of a device to prevent a toilet from leaking, the device configured to prevent the unnecessary flow of water from a fill valve having a float within a tank of a toilet, the device comprising:
a cylindrical housing, the cylindrical housing having a size to at least completely
surround the float and a portion of the fill valve to encapsulate water within an interior space of the housing, the housing comprising:
a bottom having a central aperture in communication with a stem 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 received on the bottom of the housing adjacent the bore and sized for receipt within the bore for sealing the bore;
a secondary chain, the secondary chain coupled to the secondary flop and a flush lever, wherein manipulation of the flush lever is translated through the secondary chain to the secondary flop for selectively opening and sealing the bore; and
a secondary water supply tube, the secondary water supply tube coupled to a 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 and stem are sized to receive the fill valve and allow a watertight coupling between the housing and the fill valve.
