TOILET WATER DAMAGE PROTECTION KIT AND METHOD
First Claim
1. A kit to detect leaks in a toilet when said kit is connected to a wall fluid supply, said toilet comprising a flush water inlet, said wall fluid supply comprising a supply outlet, said kit comprising:
- input and output connectors that connect said kit between said supply outlet and said flush water inlet, respectively;
a flow sensor that indicates when fluid from said fluid supply is flowing to said toilet inlet;
a latching solenoid moveable between an open position that allows fluid flow through to said toilet inlet and a closed position that prevents fluid flow to said toilet inlet;
a processor operatively connected to said flow sensor and said latching solenoid, said processor being programmed to utilize said flow sensor to measure a flush cycle time of said toilet and calculate a shutdown time, said processor being programmed to activate said latching solenoid when a time duration of fluid flow to said toilet inlet is greater than said shutdown time.

Abstract
The present invention provides an easily mounted, self-contained, compact fluid leak detection kit and/or method. When water begins to flow through the kit housing, a flow switch triggers a timer mechanism such as a processor. As long as the flow continues, the timer mechanism will count down the amount of preset time. The kit provides a manual or computer controlled adjustment to set a predetermined delay time or shutdown time, which is adjustable to the normal operating cycle time of any particular toilet. In this way, the water is shut off as quickly as possible if a leak occurs. The kit may also provide overflow protection, reset to initial values, low battery indication, and bypass function with suitable hardware to implement each.

6. An apparatus to detect leaks in a toilet, comprising:
-
a housing comprising input and output connections operable to connect between a toilet inlet and a flush water fluid supply that supplies water to said toilet inlet; a flow sensor mounted within said housing that senses fluid to said toilet inlet; a processor mounted within said housing operatively connected to said flow sensor; and a latching solenoid mounted within said housing moveable between an open position that allows fluid flow to said toilet inlet and a closed position that prevents fluid flow to said toilet inlet, said processor being operably connected to said latching solenoid to move said latching solenoid to said closed position when fluid flowing through said flow sensor exceeds a shutoff time. - View Dependent Claims (7, 8, 9, 10, 11, 12)

13. A method for making a flow control apparatus to detect leaks in a toilet when said toilet is connected to a toilet water supply, comprising:
-
providing a flow control apparatus within a housing with connections on said housing to fluidly connect between said toilet water supply and a toilet inlet for said toilet; providing a flow sensor within said housing that detects fluid flowing into said toilet inlet; providing a processor within said housing responsive to said flow sensor; providing a latching solenoid within said housing moveable between an open position that allows fluid flow into said toilet inlet and a closed position that prevents fluid flow to said toilet inlet, said latching solenoid being operatively connected to said processor to control fluid flow from said toilet water supply; and providing that said processor is programmed to at least one of calculating a shutoff time or detecting excessive flushing of said toilet within a time period, said processor being further programmed to terminate fluid flow through said housing when at least one of said shutoff time is exceeded or when said excessive flushing occurs. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
