Water disinfecting module, systems and methods

A water disinfecting module comprising:

• a frame supporting a hot water inlet, a hot water outlet, a cold water inlet and a cold water outlet;
• a hot water flow switch fluidly interposed between the hot water inlet and hot water outlet sensing a hot water flow from the hot water inlet to the hot water outlet, the hot water flow switch supported by the frame;
• a hot water UV treatment module fluidly interposed between the hot water inlet and hot water outlet, the hot water UV treatment module operably coupled to the hot water flow switch for activation of the hot water UV treatment module upon sensing of the hot water flow, the hot water UV treatment module supported by the frame;
• a cold water flow switch fluidly interposed between the cold water inlet and cold water outlet sensing a cold water flow from the cold water inlet to the cold water outlet, the cold water flow switch supported by the frame;
• a cold water UV treatment module fluidly interposed between the cold water inlet and cold water outlet, the cold water UV treatment module operably coupled to the cold water flow switch for activation of the cold water UV treatment module upon sensing of the cold water flow, the cold water UV treatment module supported by the frame.
