ABSTRACT:
A flush valve control apparatus for selectively closing, at the option of the operator, the flush valve of a flush toilet is disclosed. The apparatus includes a control member which is located such that it can selectively push against the flush valve which opens and closes the outlet pipe of a flush toilet. The control member which is normally in a non-control relationship with the flush valve is attached by a hinge to the standpipe such that it may be rotated downwardly until it contacts the top portion of the valve. A rod is pivotally attached to the control member at one end and slidably attached to a line at its second end. The link is attached to the handle of a trip lever, such as is normally found in conventional toilets. On forcing the trip lever downward by rotating the handle in a direction opposite to that for flushing, the link slides along the rod until it meets a stop. The link upon reaching the stop, urges the rod downward and causes the control member to rotate about its hinge and force the flap valve member downward over the opening of the outlet pipe. Upon releasing the handle, a spring causes the control member to rotate upward and return it to its normal position such that it is no longer in contact with the flush valve.
