Leak detection and response system for a pressure vessel

A leak detection and response system for a water filter system, the leak detection and response system comprising:

• a valve assembly including:
• a housing defining an internal passageway;
• an internal inlet port and an internal outlet port extending from the housing for attaching to corresponding ports of the water filter system, the internal inlet port and the internal outlet port in fluid communication with the internal passageway;
• a first and second valve port assemblies disposed partially inside the housing in fluid communication with the internal passageway;
• an external inlet port and an external outlet port extending from the housing, for connecting to an external water network, the external inlet port and the external outlet port also in fluid communication with the internal passageway;
• a leak sensor positioned in a sensor port, the sensor port in fluid communication with the internal passageway and disposed between the internal inlet port, the first valve port assembly, and the external outlet port, the leak sensor configured to generate a signal indicating a presence of water;
• a second leak sensor positioned in a second sensor port, the second sensor port in fluid communication with the internal passageway and disposed between the internal outlet port, the first valve port assembly, and the external inlet port, the second leak sensor configured to generate a second signal indicating a presence of water;
• and
• a controller configured to:
• receive the signal from the leak sensor;
• and control the first and second valve port assemblies to block water flow from the external inlet port based upon the signal.

A manifold assembly for a water filter system, the manifold assembly comprising:

• a housing having a mating surface extending between opposing sides of the housing, the mating surface for fitting to an outer surface of a pressure vessel of the water filter system, the housing defining an internal passageway;
• an internal inlet port and an internal outlet port extending from the mating surface for attaching to corresponding ports of the pressure vessel, the internal inlet port and the internal outlet port forming a portion of the internal passageway;
• first and second valve port assemblies disposed partially inside the housing in fluid communication with the internal passageway;
• an external inlet port and an external outlet port extending from the opposing sides of the housing, respectively, for connecting to an external water network, the external inlet port and the external outlet port forming a portion of the internal passageway;
• a leak sensor positioned in a sensor port, the sensor port in fluid communication with the internal passageway and disposed between the internal inlet port and the external outlet port, the leak sensor configured to generate a signal indicating a presence of water;
• a second leak sensor positioned in a second sensor port, the second sensor port in fluid communication with the internal passageway and disposed between the internal outlet port and the external inlet port, the second leak sensor configured to generate a second signal indicating a presence of water;
• and
• a controller configured to receive the signal from the leak sensor and control the valve port assemblies between an operational position, a bypass position, and a shut-off position,
• wherein:
• in the operational position, the first valve port assembly is aligned for fluid flow only from the external inlet port to the internal outlet port and the second valve port assembly is aligned for fluid flow only from the internal inlet port to the external outlet port;
• in the bypass position, the first valve port assembly is aligned for fluid flow only from the external inlet port to the second valve port assembly and the second valve port assembly is aligned for fluid flow only from the first valve port assembly to the external outlet port;
• and
• in the shut-off position, the first valve port assembly is aligned to block fluid flow from the external inlet port.
