Example aspects of a remote-operated flushing system and a method of operating a flushing system are disclosed. The remote-operated flushing system can comprise a fluid routing assembly comprising a valve, the valve configurable in an open configuration, wherein fluid is permitted to flow through the fluid routing assembly, and a closed configuration, wherein the fluid is prohibited from flowing through the fluid routing assembly; a control device configured to actuate the valve between the open configuration and closed configuration; a remote operation device wirelessly connected to the control device and configured to remotely operate the control device to control the actuation of the valve between the open configuration and closed configuration; and a sensor configured to detect a fluid property of the fluid within the fluid routing assembly, wherein the control device is configured to wirelessly send a signal representative of the fluid property detected by the sensor.

An outlet valve includes a valve body, a solenoid valve, and a manual operating member. The valve body includes a water inlet, a water outlet, a water storage cavity, a drain waterway, a first waterway, a second waterway, and a waterproof membrane. The first waterway is coupled to the drain waterway through a first drain opening. The second waterway is coupled to the drain waterway through a second drain opening. The waterproof membrane is configured to separate the water outlet cavity from the water storage cavity. The first waterway comprises a first plug coupled to an output end of the solenoid valve. The first plug is configured to control the opening and closing of the first drain opening. The second waterway comprises a second plug coupled to the manual operating member. The second plug is configured to control the opening and closing of the second drain opening.

The present invention refers to a drinking and service water system with a connection (2) to the public water supply network, at least one supply line (4, 6) leading to at least one consumer (8), a flushing valve (10) downstream of the consumer (8) in the flow direction for draining water from the drinking and service water system, a control unit (12) connected to the flushing valve (10) in terms of control, and a first temperature sensor (18) upstream of the consumer (8) in the flow direction, the control unit (12) comprising a flushing module which determines flushing processes to the control unit (12) at specific times and/or at specific time intervals. This invention is intended to provide a drinking and service water system which, with an efficient flushing device, fulfills the hygienic requirements placed on a drinking water system. To solve the problem, a second temperature sensor (20) is arranged between the consumer (8) and the flushing valve (10) and the control unit (12) is arranged to decide whether the predetermined flushing operation is to be suspended or postponed on the basis of a temperature difference between a measured value of the first temperature sensor (18) and a measured value of the second temperature sensor (20). In a secondary aspect, the present invention provides a method for flushing such a system.

An isolation device and method are provided for isolating a plumbing system of a premises from a potable water source if permissible input water pressure parameters are violated. After the plumbing system has achieved a desired input water pressure, the isolation device places the plumbing system in an isolated state and only removes the plumbing system from the isolated state if the isolation device detects a demand for water from the plumbing system and if the isolation device determines that permissible input water pressure parameters are not being violated. Once the demand no longer exists, the isolation device returns the plumbing system to the isolated state.
