1. A detection system for detecting blockage, comprising:

  • a first sensor adapted to be coupled to a pipe associated with a pump, wherein the first sensor generates temperature data associated with a temperature of the pipe, the temperature data representative of at least one temperature value;

    a second sensor adapted to be positioned within an acoustic sensing distance from the pump, wherein the second sensor generates sound data associated with a sound of the pump, the sound data representative of at least one sound value; and

    a processing device configured to execute data instructions, wherein the data instructions cause the processing device to;

    store a baseline temperature signature and a baseline acoustic signature;

    receive the temperature data from the first sensor and the sound data from the second sensor; and

    based on (1) a determination that flow through the pipe is reduced by comparing temperature data to the baseline temperature signature, and (2) a determination that the pump remains operational based on comparing the acoustic data to the baseline acoustic signature, generate an indication that the pipe is blocked.
