An improvement in a commode having a waste evacuation passageway comprising a toilet bowl with a drain line communicating therewith and a fresh water flush system having an outlet into said bowl and valve means to control the flow of water therethrough, said improvement comprising: a switch assembly mounted on said commode and activated by an abnormally high water condition therein; and water flow blocking means mounted in said flush system connected to and operated by said switch to prevent the flow of water therein when said switch assembly is activated by an abnormally high water condition in said commode.

Claim 3

An improvement according to claim 1 wherein said flush system includes a water closet having an outlet in the bottom thereof and said valve means is operable by a flush handle assembly mounted on said water closet, and said blocking means comprises a solenoid mounted on said water closet and having a plunger disposed to block said handle to prevent the movement thereof when said solenoid is activated by said switch.

Claim 4

An improvement according to claim 1 wherein said switch assembly is mounted on said toilet bowl and includes a float pivoted thereto and operably connected therewith such that the rise of water in the toilet bowl beyond a predetermined level activates said switch.

Claim 5
