Purge controllers for plumbing systems

A purge controller for a plumbing system, the purge controller comprising:

• a processor:
• an interface adapter coupled to the processor, the interface adapter configured for electrical communication with an actuator of at least one purge valve incorporated within the plumbing system proximate to a drain outlet of such plumbing system:
• at least one temperature sensor adapted to transmit information indicative of a temperature to the processor, said temperature sensor for location proximate to at least a portion of the plumbing system;
• and
• a power input for receiving power from a primary power source to provide power to the processor and the interface adapter,
• wherein the processor is configured such that when the processor receives transmitted information from the at least one temperature sensor indicating that a corresponding detected temperature drops below a first threshold temperature the processor causes the interface adapter to send a purge signal to the actuator of the at least one purge valve to activate such valve and purge fluid from the plumbing system into the drain outlet,
• wherein the plumbing system comprises a toilet check valve between a portion of the plumbing system and a toilet tank, wherein when pressure within the plumbing system proximate to the at least one purge valve falls below a threshold pressure, the toilet check valve opens and permits water from the toilet tank to flow back into the plumbing system,
• and wherein the toilet comprises a secondary float-actuated valve connected to an anti-freeze source, and wherein when the water level in the tank falls below a threshold level, the float-actuated valve operates to admit anti-freeze into a bowl of the toilet from the anti-freeze source.

A purge controller for a plumbing system, the purge controller

• comprising:
• a processor;
• an interface adaptor coupled to the processor, the interface adaptor configured for electrical communication with actuators of purge valves within respective zones of the plumbing system proximate, said purge valves being proximate to at least one drain outlet of such plumbing system;
• a plurality of temperature sensors with at least one of the temperature sensors proximate a respective one of the zones of the plumbing system, each of the temperature sensors adapted to transmit information indicative of a temperature proximate to said temperature sensor to the processor;
• and
• a power input for receiving power from a primary power source to provide power to the processor and the interface adaptor,
• wherein the processor is configured such that when the processor receives transmitted information from the at least one temperature sensor in a respective one of the zones indicating that a corresponding detected temperature dropped below a first threshold temperature for such zone, the processor causes the interface adaptor to send at least one purge signal to the corresponding actuator of the at least one purge valve within such zone to activate such valve and purge fluid from the corresponding zone of such plumbing system into the at least one drain outlet, and
• wherein the processor is configured for communication with a controller of a dedicated standby generator adapted to activate and provide electrical power to a heating system upon a (a) loss of power from a power source to the heating system and (b) transmitted information from the at least one temperature sensor in a respective one of the zones indicates a temperature that is below a second threshold temperature, and
• wherein the second threshold temperature is a temperature at or above the first threshold temperature.
