How often should the lint, dust, and oil screen on a water heater tank be inspected?

The correct answer reflects the general recommendation for inspecting the lint, dust, and oil screen on a water heater tank, which is once a year. Regular annual inspections help ensure that these components remain clean and functioning properly. Over time, lint and dust can accumulate on the screen, potentially affecting the efficiency of the water heater and leading to issues such as overheating or improper function.

Annual inspections allow for timely maintenance actions, such as cleaning or replacing filters, which can enhance safety and extend the lifespan of the water heater. This routine check-up aligns with standard homeowner maintenance practices that aim to prevent larger issues down the line.

Options suggesting more frequent checks might not be practical for most homeowners, given that monthly inspections could be excessive unless specific conditions warrant it. Similarly, suggesting inspections as needed or every five years may not provide sufficient oversight after prolonged usage, which could lead to safety hazards or diminished efficiency in the water heater’s performance.
