Check These Three Things Before You Call Anyone
Your hot water heater not working? Before you call, check a few things yourself, you might save a service call.
Check the power supply. For electric units, check the circuit breaker, a tripped breaker is the most common cause of no hot water. If it trips again immediately, call for help.
Check the pilot light. Gas water heaters have a pilot light; if it's out, relight it using the ignition button near the tank's base. If it won't stay lit, you'll need professional help.
Check for leaks. Water pooling at the tank's base or connections means a leak. A leaking tank usually needs replacement, not repair.
If none of these fixes work, it's time to call someone.
Plumber or Electrician for Water Heater: Which Professional You Need

Frequently Asked Questions
Do I call a plumber or electrician when my hot water heater isn't working?
Start with a licensed plumber for most water heater problems. Plumbers handle tank diagnosis, sediment buildup, pressure relief valve issues, and replacement. Call an electrician if you suspect electrical connection problems or a faulty heating element in an electric unit. For gas units with ignition or pilot light issues, a plumber is usually the right choice, though some may refer you to an HVAC technician for gas line concerns.
When should I call an emergency plumber for a water heater?
Call immediately if you see water pooling around the tank, smell gas near the unit, notice sparks or burning smells, or have no hot water and need it urgently. Before calling, turn off the water supply at the shutoff valve and turn off power at the circuit breaker (electric) or the gas valve (gas). This prevents further damage and ensures safety while you wait for help.
What should I tell a plumber about a water heater problem?
Describe when the problem started, whether you have no hot water or inconsistent hot water, and note the unit type (gas or electric). Mention any sounds (rumbling, popping), leaks, or odors. If you checked the thermostat, circuit breaker, or pilot light, say what you found. This information helps the plumber diagnose the issue faster and come prepared with the right tools and parts.
