What’s safe to do

Smell gas? Leave immediately. From outside, call 911 and your gas utility.

Boiler or heat is out

  1. Thermostat set to HEAT and above room temperature.
  2. Check the boiler’s circuit breaker. Reset it if tripped.
  3. Check the power switch on or near the boiler. It often looks like a light switch.
  4. Hot-water boilers only: note the pressure gauge reading. Normal is typically 12–25 PSI. Steam boilers run far lower, so don’t compare them.
  5. Don’t attempt to repair any boiler components yourself.

Water heater is leaking

  1. Find the cold water supply valve on top of the heater and turn it off.
  2. On gas units, turn the gas valve to PILOT.
  3. Call us right away. A leaking tank often needs emergency replacement.
