Pool pump not priming — Leiden, Zuid-Holland

A pool pump that runs but fails to prime cannot circulate or filter the water, leaving the pool vulnerable to algae growth and chemical imbalances. Common causes include an air leak in the suction line, a clogged impeller, a cracked pump lid, or a low water level in the pool. A pool technician inspects the suction plumbing for air leaks, clears the impeller and strainer basket, replaces worn gaskets or a cracked lid, and verifies the pump achieves full prime with steady flow.
