Abstract: A flush valve adapter for a tankless toilet having a flush valve housing and a vacuum breaker member includes a conduit body having a first end and a second end; a female threaded interface located at the first end of the conduit body; a male threaded interface located at the second end of the conduit body; and an outlet port member located in the conduit body between the female threaded interface and the male threaded interface. A vacuum breaker adapter for a tankless toilet having a flush valve housing includes a conduit body having a first end and a second end; a female threaded interface located at the first end of the conduit body; a vacuum breaker mechanism located at the first end of the conduit body; an inlet port member located in the conduit body between the vacuum breaker mechanism and the second end of the conduit body; and a cleaning agent mixing chamber interface member located on the conduit body between the vacuum breaker mechanism and the inlet port member.

Abstract: A cleaning agent dispensing system for a toilet includes a transparent cleaning agent mixing chamber configured to mix water with a cleaning agent tablet and a tablet cradle configured to hold a cleaning agent tablet within the transparent cleaning agent mixing chamber. The tablet cradle includes a housing, multiple apertures, in the housing, configured to allow water to flow therethrough, and a three-dimensional opening, in the housing, configured to enable a substantially unobstructed view of a cleaning agent tablet within the transparent cleaning agent mixing chamber.

Abstract: A system for monitoring hand washing compliance that includes a plurality of sensors installed in a space to detect the presence of or proximity of personnel to key areas; and a controller operatively coupled to the sensors, the controller being programmed to analyze sensor inputs to determine if personnel are washing their hands in a manner compliant with a set of requirements, and a networked data storage and reporting system operatively coupled to the controller and configured to provide reports of hand washing compliance. The sensors are installed on a ceiling over the space and an LED light illuminates a hand washing area for an interval of time that begins in response to detection by one of the plurality of sensors that a user is in proximity to the sink and ends when hand washing compliance is complete.
