Abstract

Disclosed is a toilet bowl water level gauge and associated methods. In one embodiment, the toilet bowl water level gauge comprises a gauge assembly having a stem with a float, and a sleeve, wherein the stem is inserted in the sleeve and slides through the sleeve. Also, the toilet bowl water level gauge comprises a support attached to the gauge assembly, the support being adapted to engage a rim of a toilet bowl. In addition, bowl level sensors are employed for automated calibration of an automated bowl fill system.

Claims (6)

1. A method of controlling the flow of water from a fill valve in a toilet tank to a toilet bowl of a toilet using a bowl fill valve, wherein an inlet of the bowl fill valve is coupled to a bowl fill outlet of the fill valve and the outlet of the bowl fill valve is channeled to the toilet bowl, the method comprising the steps of:

opening the bowl fill valve for a predefined period of time after the toilet tank has been substantially drained of water via a flapper valve during a flush cycle to fill the toilet bowl of the toilet with water, wherein the predefined period of time is less than a refill time of the toilet tank during the flush cycle; and

calibrating the predefined period of time.

2. The method of claim 1 , wherein the step of calibrating the predefined period of time is performed manually.

3. The method of claim 1 , wherein the step of calibrating the predefined period of time is performed automatically.

4. The method of claim 3 , further comprising the step of positioning a bowl level sensor relative to an amount of water in the toilet bowl to detect when a level of the water in the toilet bowl has reached a maximum height of the toilet bowl before the water begins to overflow down the drain of the toilet.
