Irrigation pumps should be tested every three to five years to catch efficiency losses before they raise energy costs. A pump test measures flow rate, discharge pressure, water level, and power use to calculate overall pumping plant efficiency. Worn impellers, wrong settings, or a dropping water table often show up as higher energy bills first.

Common warning signs include reduced flow or pressure, higher energy bills, unusual noise or vibration, frequent cycling, and air or sand in the water. These often point to worn impellers, bearing wear, a failing seal, or a dropping water level in the well. Catching them early prevents motor burnout and costly downtime during peak season.

Pump efficiency testing measures the water delivered against the energy used, giving an overall pumping plant efficiency percentage. Technicians record flow, pressure, pumping water level, and input power, then compare results to the pump's design curve. The report shows whether a pump should be adjusted, rebuilt, or replaced and estimates annual operating cost.

Many issues such as pressure switches, seals, wiring, and motor faults can be handled in the field, but worn turbine bowls or submersible units usually must be pulled for inspection. The decision depends on the pump type, the depth, and the nature of the fault. A field test usually determines which path is needed.
