    The 4 plumbing issues that fail LA health inspections

    Get the full list of 7 in the free guide — these are the most common.

    Grease trap not cleaned on schedule

    LA County requires documented cleaning at intervals based on seating capacity. Missing records = automatic citation.

    Backflow preventer not tested annually

    Commercial kitchens must have annual backflow preventer tests by a certified tester. Test records must be available on-site.

    Hand wash sink not properly plumbed or blocked

    Every handwashing station must have hot and cold water, be accessible, and not used for food prep or storage.

    Inadequate hot water temperature

    Water heaters must supply hot water at 120°F+ at all sinks. An aging or undersized water heater frequently fails this check.
