Common Causes of Swimming Pool Pump Failures

November 11, 2016

Swimming pools hum with synergy as freshwater laps at the edges of their clean concrete basins. Regrettably, this unsullied setting can't exist when pool pumps break down, for the water is no longer circulating and being conditioned. Stop this ambiance and health corrupting scenario by understanding the common causes of swimming pool pump failures.

Motor Mishaps

Signs of a breakdown can be found by listening to the background hum of the motor. A grinding sound suggests motor bearing problems. Conversely, a silent pump indicates a dead motor, so the pool has just gained a 12kg paperweight. A circuit breaker reset could correct this issue, but it won't fix the underlying cause. Speaking of overloads, a loud hum is a dead giveaway that something untoward is taking place. In all likelihood, the bearings have frozen or there's a serious clog in the line.

Impeller Inaction

As the motor provides raw electromagnetic power, the impeller at the end of the drive shaft delivers rotational force. A damaged impeller provides little to no fluid momentum. The motor potentially enters a parts-damaging overload phase while attempting to compensate for lost flow, which then results in more hum and a shorted circuit breaker. Listen for the hum of the motor and the noise of rattling drive parts.

Leaking Liquids

Pumps are excellently engineered function isolators. After all, electricity and water don't mix. A fatigued seal undermines this feature. Shaft seals wear, so the fluid works its way into the windings of the motor. The result is corrosion and an electrical compartment that's destined to fail. Watertight by design, swimming pool pump failures commonly crop up as a result of housing gasket leaks and drive seal wear. Fortunately, new polymers can dramatically extend the lifespan of these critical seals.

Inlet Issues

On the plumbing side, air leaks pervert smooth pump functionality. The mechanism acts unpredictably if bubbling water is changing the load acting on the motor impeller. Irregular flow conditions then cause a subsequent spike in the motor's energy consumption, so it heats up and wears. Other water conduit problems include priming errors and clogs, all of the issues that can and will engender an eventual full system failure.

The swimming pool pump is the heart of a living system. It propels water through chemical conditioners and mechanical filters so that pool stagnancy is never an issue. Instead, the processed water is energetically circulated. In knowing the common causes of swimming pool failures, we're maintaining this healthy setting.
