Suburban tank water heater rotten-egg odor or anode issue

Use this when hot water from a Suburban tank water heater smells like sulfur or the anode rod needs inspection, draining, or replacement planning.

Owner-safe checklist

  • First decide whether the odor is hot-water odor or possible LP gas odor; use the gas-smell guide if gas odor is possible.
  • Turn the water heater off and let it cool before draining or flushing.
  • Use only Suburban-approved anode parts and owner-accessible drain or flush steps you can perform safely.
  • Call qualified service if the anode rod, drain fitting, leaks, or persistent odor require work beyond normal owner maintenance.
