Dispense and leak detection systems and methods

A method, comprising:

• detecting, via a computing device, completion of a fluid dispensing event based on a pressure measurement from a second pressure sensor positioned between a demand pump and at least one dispensing valves;
• after a predefined duration from completion of the fluid dispensing event, determining, via a computing device, a first pressure measurement at a first pressure sensor between a backflow preventer and an inlet valve and a second pressure measurement at the second pressure sensor;
• and
• determining, via a computing device, a leak in a fluid pathway based on a change in a pressure at one or more of the first pressure sensor or the second pressure sensor from at least one of:
• the first pressure measurement or the second pressure measurement.

A cabinet assembly, comprising:

• an inlet valve;
• a backflow preventer;
• a first pressure sensor coupled to at least one computing device, wherein the first pressure sensor is configured to measure pressure between the backflow preventer and the inlet valve;
• a second pressure sensor coupled to the at least one computing device, wherein the second pressure sensor is configured to measure pressure between the backflow preventer and at least one dispensing valves;
• and
• the at least one computing device is configured to:
• detect completion of a fluid dispensing event based on a pressure measurement from the second pressure sensor;
• after a predefined duration from completion of the fluid dispensing event, determine a first pressure measurement at the first pressure sensor and a second pressure measurement at the second pressure sensor;
• and
• determine a leak in a fluid pathway based on a change in a pressure at one or more of the first pressure sensor or the second pressure sensor from at least one of:
• the first pressure measurement or the second pressure measurement.
