Common Water Heater Problems and How to Troubleshoot

1. No Hot Water

This is one of the most common complaints. The fix depends on your water heater type.

Electric Units:

  • Check for a tripped breaker or blown fuse.
  • Inspect the thermostat or heating elements.

Gas Units:

  • Ensure the pilot light is lit.
  • Check the gas supply valve and thermocouple.

2. Inconsistent or Lukewarm Water

  • Adjust the thermostat to 120–140°F.
  • Flush the tank to remove sediment buildup.
  • Check for failing heating elements or dip tube issues.

3. Leaking Tank

  • A faulty temperature and pressure relief valve (T&P valve).
  • Loose drain valve.
  • Internal corrosion—tank replacement may be necessary.

Call for professional help if you spot an active leak. Leaks often require urgent plumbing repair services.

4. Strange Noises (Rumbling, Banging, or Sizzling)

  • Usually indicates sediment buildup.
  • Flushing the tank annually may resolve the issue.
  • If sounds persist, internal parts may need to be replaced.

5. Discolored or Smelly Water

  • Bacteria buildup in the tank.
  • A failing anode rod.
  • Pipe corrosion.

Schedule a system flush or anode rod replacement to fix the issue.

Preventative Tips to Avoid Future Issues

  • Flush your tank once a year to remove sediment.
  • Inspect the anode rod every 2–3 years.
  • Test the T&P valve regularly.
  • Consider professional water heater maintenance to catch problems early.
