Read the circulation symptoms correctly
A pool pump drawing air, struggling to prime or losing suction may point to a restriction or air entering the suction side. Water escaping from a return-line joint can behave differently when the pump runs and when it stops. Neither symptom proves the pool shell is sound or defective. We ask for observations of the water level, whether bubbles appear at the return jets, and whether the filter valve or pipework was changed recently. Those clues support a sensible inspection sequence.
