No hot water? Here’s what to do right now.
If you smell gas, leave first and call from outside. Otherwise, no hot water is a job for today, not an emergency.

First, this.
Smell gas? Leave, then call
If you smell gas (rotten eggs), leave immediately on foot. Do not use switches, phones, or anything that could spark. From a safe distance call 911 and your gas utility.
SourceElectric? Breaker off first
For an electric water heater, turn off power at the circuit breaker before touching wiring or panels.
SourceFlooded heater? Don’t light it
If a gas water heater has been underwater, do not try to operate it. Contact the gas utility or a qualified service professional for a safety inspection.
SourceLeave the gas to a professional
If the gas was turned off, do not turn it back on yourself; only a qualified professional should restore it.

Safety first
- CPSC urges setting water heaters to 120 degrees F to prevent scalds; even at 120 degrees, a five-minute exposure could cause third-degree burns. Source
- Keep gasoline and other flammable liquids away from a gas water heater. Their vapors can reach the burner or pilot light and ignite in a flashback fire. Source
- Install a hardwired carbon monoxide alarm with battery backup near a fuel-fired water heater. Source
- The temperature and pressure relief (TPR) valve is a safety device that releases hot water or steam when pressure or temperature builds up too high; test it yearly per the manufacturer. Source
What to tell the plumber
- Gas or electric, and tank or tankless.
- Brand, capacity (gallons), and age from the label on the unit; a photo of the label helps.
- Where it is installed (garage, attic, closet, utility room).
- The symptom: no hot water, not enough hot water, leaking (where), dripping relief valve, pilot will not stay lit, odd noises.
- Whether you have shut off the power or gas and the cold-water supply.
