A controller controls a fluid pump to deliver primary fluid from a first source at a desired rate through a respective conduit to a recipient. The controller monitors a volume of the primary fluid injected into the conduit. Subsequent to injecting a predetermined amount of the primary fluid into the conduit, the controller i) discontinues injection of the primary fluid into the conduit and ii) injects a secondary fluid through the conduit to advance a remaining portion of the primary fluid in the conduit to the recipient. The controller advances the secondary fluid into the conduit until a desired amount of the primary fluid is delivered trough the conduit to the recipient. Injection of the secondary fluid to push the remaining portion of the primary fluid reduces waste associated with the primary fluid.
