Look at where it happens
Identify the hot-water problem accurately
Describe whether the issue is too little heat, unexpectedly hot water, changing temperatures, noises or leaking. Explain whether every outlet behaves the same way. A concern at one fixture, including an unusual balance of hot and cold water, may need investigation beyond the water heater itself.
Avoid using an outlet producing unexpectedly hot water until the concern has been assessed. Report an active leak when you call. The inspection should connect the symptom to a cause and explain whether repair is practical. A failed component and a unit with wider deterioration do not automatically call for the same next step.
