UV light sanitizing solutions for sanitary wares

A flush valve assembly comprising:

• a flush valve housing mounted above a sanitary ware and spaced apart from a wall on the same side of the wall as the sanitary ware, wherein the flush valve housing houses a flush valve that is configured to be fluidically connected to and receive flush water from a water supply;
• a flush water delivery pipe comprising an inlet end that is fluidically connected to and configured to receive the flush water from the flush valve and comprising an outlet and that is fluidically connected to and configured to deliver the flush water to a sanitary ware;
• an ultraviolet (UV) light source housed at least partially within the flush valve housing and positioned on the same side of the wall as the sanitary ware, wherein the UV light source is configured to emit UV light through an aperture formed in the flush valve housing, wherein the emitted UV light illuminates a target disinfection volume and wherein the UV light source is adjustable between at least a first directional configuration and a second directional configuration, wherein, in the first directional configuration, a center-line of the target disinfection volume is directed in a first direction from the UV light source, and, in the second directional configuration, the center-line of the target disinfection volume is directed in a second direction from the UV light source that is different from the first direction;
• and
• a controller comprising one or more processors, wherein the controller is electrically coupled to the UV light source, and wherein the one or more processors are configured to cause the controller to:
• detect that one or more activation conditions have been met;
• and
• in response to detecting that the one or more activation conditions have been met, activate the UV light source.
