ABSTRACT:
A flush tank includes an outlet pipe attached to a receptacle for discharging water, a float disposed close to the outlet pipe to selectively block the outlet pipe, and to control an outward flowing of the water through the outlet pipe. A magnetically forcing device may magnetically force the float to block the outlet pipe, and a detecting device may be used to detect users and to actuate the magnetically forcing device to release the float. The magnetically forcing device includes an electromagnetic device supported by a frame to act with the float. A stop may be attached to the frame to limit a movement of the float relative to the outlet pipe.
