A method of determining a health status of the various components of the pumping equipment on a pump unit may include an automatic diagnostic process with one or more diagnostic tests executing on a unit controller. One or more of the diagnostic tests can establish a flow path through the piping network comprising a supply pump and a sensor valve. The diagnostic test can include positioning the sensor valve in a first and second position while operating the pump to communicate a fluid via the flow loop. The method includes comparing a set of results of the diagnostic test to an operational indicator set, determining the health status based upon the comparison, and outputting indicia of the health status of the pumping equipment.
