Water heaters combine three things that reward caution: gas or high-amperage electricity, water stored above 120°F, and a sealed pressure vessel. That does not mean a homeowner can do nothing — it means knowing where the line is.
Reasonable to check yourself
- Whether the circuit breaker for an electric unit has tripped
- Whether the gas shutoff valve serving the unit is open
- The thermostat setting — 120°F is the usual recommendation for safety and efficiency
- Whether the pilot light is out on an older gas unit, following the manufacturer's relighting instructions on the label
- Looking for water around the base and noting where it appears to originate
Call a licensed plumber for
- Any water coming from the tank body itself
- A relief valve that is discharging
- Gas smell of any kind — leave the building first and call the gas utility
- Replacing heating elements, thermostats, gas control valves, or thermocouples
- Any venting or combustion air concern, including soot or scorching near the draft hood
- Full replacement of the unit
Why replacement is licensed, permitted work here
Massachusetts requires water heater installation to be performed by a licensed plumber under permit. The reasons are venting, combustion air, thermal expansion control, and relief valve discharge — every one of which is a genuine safety issue rather than paperwork. An unpermitted installation can also create problems at the time of sale.
Maintenance worth doing
Flushing sediment annually extends the life of a tank unit, and testing the relief valve occasionally confirms it is not seized. If you are not comfortable doing either, they are quick items to fold into a service visit.
