Practical context
A symptom is useful because it narrows the problem, but it does not solve the problem by itself. That is why the page explains the likely service families, the reasons the symptom can appear, and the kinds of access checks that usually happen on site. For sump pump not working?, the user may be dealing with a one-time glitch, a maintenance warning, or a deeper repair need. The page is designed to separate those possibilities without sounding mechanical. The related links move the reader into the main service page and the relevant cities so the path stays practical.
