What are the signs of a failing pool pump?

The signs of a failing pool pump primarily revolve around its ability to circulate water effectively. Reduced water circulation is a key indicator because it means that the pump is not moving enough water through the filtration system, which can lead to problems such as algae growth and poor water quality. When the pump is functioning properly, it should create a consistent flow throughout the pool, ensuring that debris is filtered out and chemicals are distributed evenly.

Increased pump noise often accompanies a failing pump. This noise can result from various issues, such as worn bearings or a clogged impeller, indicating that mechanical components are under strain. A healthy pump should operate relatively quietly, aligned with its design specifications.

Other options may include symptoms that could indicate different issues than mechanical failure, but the combination of reduced circulation and increased noise specifically points to pump malfunction. These indicators should prompt further examination of the pump's health and operational performance.
