Abstract: An automated water purging apparatus prevents dispensing of contaminated water by volumetrically flushing a standing volume of water between a tap and an exterior inlet as required. Volumetric control of flushing and usage monitoring between flushing events minimize water waste and delivery delays. Embodiments operate in demand and/or periodic modes, and switch therebetween according to a user-specified schedule. A controller and valve can be powered by a battery that is recharged by energy derived from water flow through the apparatus. Wireless and/or network connectivity can enable remote communication with the controller via a remote console and/or other wired and wireless devices. Embodiments take partial purge usage volumes into account when determining if standing water is contaminated. Partial purge volumes can include volumes shared with other taps. Embodiments can alert users to potential leaks. Embodiments include a volumetric flow sensor at the external inlet shared among a plurality of taps.

Abstract: The present application relates to an apparatus of joined valves used to test and maintain refrigeration systems. More particularly, the present application provides a Multiple Valve Refrigerant Leak Protection Device having a specifically preferred embodiment including a ball valve with a soldered pipe connection, as part of the fitting with a Schrader valve, primarily used for the maintenance and transfer of refrigerant from commercial refrigeration equipment.
