A self-priming pump system having a repriming valve opened in response to variations in fluid movement through a reservoir that includes a flow restriction. A control system is provided that includes a first sensor for sensing pressure within the flow restriction, a second sensor for sensing pressure within a portion of the reservoir spaced from the flow restriction, and a control mechanism for comparing the sensed signals and for opening the repriming valve when the difference between the signals falls to or below a predetermined value.
