An improved and redundant system to prevent leakage from a toilet tank and into a toilet bowl. The device comprises a housing configured to surround a float and including sidewalls and bottom portion with a bore hole. A secondary flop is configured for receipt into and for sealing the bore hole when leakage occurs.

A flush toilet comprised of a tank having a first compartment for holding a first type of water, and a second compartment for holding a second type of water. The first compartment is separated from the second compartment by a divider that prevents the first type of water from mixing with the second type of water. The first type of water can be city water while the second type of water can be rainwater.

An operating device includes a rotary shaft, an operating handle, an operating wire, and a drive unit; wherein this drive unit includes: a rotary member, a rotary windup member, a locking device for mutually locking the rotary member and the rotary windup member until the rotary windup member rotates in the forward rotational direction from a first operating position and reaches a second operating position, a lock release device for releasing the lock between the rotary member and the rotary windup member so the rotary windup member rotates in the reverse rotational direction and moves to the first operating position regardless of any operation of the operating handle when the rotary member and the rotary windup member reach the second operating position, and a biasing device for restoring the rotary member to an initial position at which a toilet flush operation can be started from the operating position.

A siphonic flush toilet system, the system comprising a bowl, a tank, and a rim flush valve assembly and/or a jet flush valve assembly, the tank comprises an interior space configured to hold fluid; and a height, a width, and a depth, based on a tank exterior, wherein the height is from about 17.0 inches to about 29.0 inches; the width is from about 10.5 inches to about 18.5 inches; and he depth is from about 3.10 inches to about 3.60 inches; the flush valve assembly is positioned in the interior space of the tank; and the tank is configured to be positioned within a bathroom wall cavity upon installation of the toilet system.

Flush valve assemblies are described herein which include a valve body; a flush valve cover detachably connected to a flush line; a pivot mechanism capable of opening and closing the flush valve cover upon actuation; wherein the flush line is connected at a first end to a flush actuating device and at a second end to the flush valve cover, the line being capable of raising and lowering the cover upon actuation; and a float situated above the cover and connected to the flush line at a point between the first and the second ends of the flush line or by a separate float line connected to the cover. The float is sufficiently buoyant and capable of resisting the force of flowing water and keeping the flush valve cover open to allow flush water to pass through the valve body before closing the cover when the valve body is installed on a toilet.

An apparatus comprises a ring, a top portion, and a bottom portion. The apparatus further comprises a first leg and a second leg. In addition, the apparatus comprises a horizontal portion. The horizontal portion connects the first leg and the second leg. The legs and horizontal portion, together with an adhesive, overlay and sealingly engage the top rim of a flush valve wall, which is part of a toilet flush valve.

An improved and redundant system to prevent leakage from a toilet tank and into a toilet bowl. The device comprises a housing configured to surround a float and including sidewalls and bottom portion with a bore hole. A secondary flop is configured for receipt into and for sealing the bore hole when leakage occurs.

A toilet plunger structure is disclosed. It comprises a shell having a handle, a trigger pivotally connected to the handle and having a push part, an accommodating slot corresponding to the push part for accommodating a gas container and a positioning slot; a smasher having a positioning seat accommodated in the positioning slot of the shell and having a positioning hole and a firing pin disposed in the positioning hole; a gas pipe provided with a connecting pipe having a connecting seat connected to the positioning seat for fixation, a protecting pipe sleeved on the connecting pipe and a connecting member connected to the protecting pipe; and a dredge connector having a connecting part for correspondingly connecting the connecting member, a plugging part disposed at a bottom of the connecting part and a though hole passing through the connecting part to the plugging part for receiving the connecting pipe.

The present disclosure describes toilet flappers having an adjustable length cord. For example, the present disclosure describes a toilet flapper having a body and two arms. The body has a top surface and a bottom surface. On the top surface, there is a raised portion housing a cord, a locking mechanism, and a spring. In order to install the toilet flapper, a user can grab a hook attached to the end of the cord and pull enough of the cord out of the raised portion so that the user can attach the hook to, for example, a flush lever. Afterwards, the user can press down on the raised portion in order to activate the locking mechanism and prevent any more of the cord from being pulled back into the raised portion by the spring.

A volume controllable toilet flush system, comprising: a cistern configured to hold and retain a fluid; a vertically moveable siphon assembly comprising a siphon portion, a pipe and at least one resilient element attached to the pipe; a toilet bowl shaped to retain and hold waste; an actuator operatively connected to the pipe by a stud attached to the pipe and configured to provide vertical movement to the siphon assembly, wherein movement of the siphon assembly by the actuator stores or releases energy in the at least one resilient element and, wherein downward vertical movement of the siphon assembly puts the toilet bowl in fluid communication with the cistern by creating a siphoning action between the siphon portion and the fluid in the cistern and wherein subsequent upward vertical movement of the siphon assembly terminates the siphoning action to stop fluid flow from the cistern to the toilet bowl.
