If the drawdown in a well has decreased and the motor amps are high, what is the most likely problem?

When there is a decrease in drawdown alongside high motor amps, it indicates that the pump is experiencing an inefficiency in its operation. A decrease in drawdown typically suggests that the well is no longer producing water at the same levels as before, which could be caused by several factors related to the pump system.

High motor amps signal that the motor is drawing more electrical current than normal. This condition often occurs when the motor is working harder than it should to maintain its desired performance; one possible cause for this increased load is friction or resistance in mechanical components. When line shaft bearings are problematic—such as due to wear or insufficient lubrication—they can create excessive friction, causing the motor to work harder, leading to higher amps.

This relationship between line shaft bearings and increased motor load helps to clarify why a problem with bearings would manifest as both reduced output (drawdown) and elevated amp readings. Addressing line shaft bearing issues is essential to restore efficient operation, as proper bearing function reduces resistance and ensures that the pump runs smoothly, thereby improving drawdown and lowering the motor’s electrical draw.
