Dayton Plumbing Expert specializes in rapid, accurate diagnostics to isolate the root mechanical or structural failure and implement permanent solutions.

Primary Causes of Water Heater Pilot Light Keeps Going Out

Our experienced technicians have investigated hundreds of instances of this issue across Dayton. The most frequent causes include:

  • Underlying Factor: Defective or soot-covered thermocouple failing to send millivolts to the gas control valve
  • Underlying Factor: Drafts or negative basement air pressure blowing out the small pilot flame
