Error or Warning Message
Pump PMP-1 cannot deliver flow or head.
Explanation
This message normally happens if the pump was trying to operate at the shutoff point (zero flow), but it will also show iff the pump is operating beyond the defined pump curve. WaterCAD/GEMS will extrapolate out the pump characteristic curve past the maximum operating point if the curve does not go out to zero head, but it is not desirble for a pump to operate past the defined pump curve.
