AUTOMATIC SHUTOFF ASSEMBLY FOR A WATER CLOSET
First Claim
1. An automatic shutoff valve and sensor assembly suitable for use with a water closet positioned in a room, the assembly comprising:
- a housing mountable upstream of the water closet, the housing having an inlet water port connectible to a water supply for the room and an outlet water port connectible to the water closet;
a shutoff valve positioned in the housing;
an automated sensor positioned in the housing; and
a microcontroller coupled to the sensor and shutoff valve;
wherein if the assembly is positioned in the room, linked to a water supply for the room and the water closet, and supplied with electrical power, the sensor is suitable to detect when a potential user is adjacent the water closet, and if it does so detect an adjacent potential user, the sensor can send an output signal to the microcontroller such that the microcontroller can open the shutoff valve.

Abstract
An automatic shutoff valve and sensor assembly is disclosed to control water supply to a toilet. There is a housing mountable upstream of the toilet and downstream of the room water supply. There is also a shutoff valve, an automated sensor, and a microcontroller in the housing. The sensor is suitable to detect when a potential user is adjacent the water closet. If it detects a user, the sensor can send an output signal that ultimately leads to the opening of the shut-off valve. The shutoff valve then later automatically re-closes when users aren'"'"'t present. A manual override can be incorporated in the housing as well. This reduces the potential for water leaks and water waste from the toilet.
