Hanson · Water Heaters
No hot water, a leaking tank, or rusty water in a Hanson home? Call or send a request to be connected with an independent local plumber who can check gas, oil, propane, or electric units.
Hanson, Massachusetts
In Hanson, the first thing a plumber wants to know is what heats your water. Census estimates for 2019 to 2023 put utility gas in 55.9 percent of occupied homes and fuel oil or kerosene in 32.5 percent, with smaller shares on propane and electricity. A gas tank, an indirect tank fed by an oil boiler, and an electric unit each fail differently, and each brings its own permits.
The water matters too. Hanson's well water is naturally corrosive, and while the Water Department treats it to raise the pH, a tank's inner lining and its sacrificial anode still wear with age. Rusty hot water or a damp spot under the tank are signs to act before it lets go.
We connect Hanson homeowners with independent local plumbers; we don't do the work ourselves. If you smell gas near the heater, leave the house first and call 911 or the gas company from outside.
Sediment on the bottom of a tank or a failing element cuts how much hot water you get from each cycle.
If only the hot side is discolored, the tank's lining or anode may be corroding.
A drip from the tank body rather than a fitting usually means the tank has failed and needs replacing.
Noise while heating often comes from sediment layers boiling under the water.
Repeated outages on a gas or oil unit call for a plumber or burner technician, not repeated relighting.
Local knowledge
Fuel, water chemistry, and who issues the permit all vary here.
Treated Acidic Water
The 2025 water quality report says Hanson's groundwater has a pH below 7.0 and that sodium hydroxide is added to make it less corrosive. Corrosion inside a tank tends to show up as rusty or metallic-tasting hot water, so ask the plumber to check the anode rod during service.
Oil Burner Permits
The Hanson Fire Department's Fire Prevention Division handles oil burner installation and replacement, oil tank work, and propane tank installs and removals. If your hot water comes from an oil boiler, or a propane tank is being added, ask who files with the Fire Department.

Gas Utilities
State utility listings name National Grid and Eversource as gas companies serving Hanson. Know which one is yours before you need it, since that's who you call from outside if you ever smell gas near the heater.

Right now
Safety first, then limit the water.
Gas odor, a sooty vent, or a sounding carbon monoxide alarm means get everyone outside and call 911 or the gas company from there.
If the tank is leaking, turn the valve on the cold-water pipe feeding it to slow the flow.
If water is pooling near the heater's wiring or the electrical panel, stay out of the area and let the professionals deal with the power.
Write down the brand, size, fuel, and the date on the label so the plumber can bring the right parts.
What to expect
A plumber will check the burner or elements, thermostat, venting, relief valve, and the tank itself, then tell you whether repair makes sense. On an aging tank with corrosion, replacement is often the sounder choice, and the plumber should explain why.
Replacing a water heater generally needs a plumbing permit, and gas units also need a gas permit, filed through the Building Department at Town Hall. The town says every gas inspection requires a plumber with a license on site. Oil and propane equipment brings in the Fire Department's permit schedule as well.
Ask about the venting and the space. A new gas or tankless unit may need different venting than the old one, and cellars in older Hanson houses can be tight for a larger tank.
Hire smart
Plumbing and gas fitting in Massachusetts require a license from the Board of State Examiners of Plumbers and Gas Fitters, and most plumbing work needs a permit from the town's plumbing inspector.
Gas fitting needs its own Massachusetts license; confirm it on the state's occupational license lookup if the heater burns gas or propane.
National Grid and Eversource sponsor Mass Save, so ask whether the model you're considering qualifies for a current Mass Save offer.
The written estimate should list the plumbing and gas permits, plus any Fire Department permit for oil or propane.
Ask whether removing and disposing of the old tank is included.
Costs
Fuel type, tank size, venting changes, and whether the unit is tied to an oil boiler all affect price. Trading one tank for a similar one is simpler than switching fuels or going tankless.
Ask for a written estimate that includes the permits, removal of the old unit, and any venting or gas line work. Check Mass Save's current residential offers before you decide, since rebates can change the comparison for a more efficient unit.

Questions
Still not sure? Send a short request and a local pro can answer the specifics.
If only the hot side is discolored, the tank's lining or anode is likely wearing out. Hanson's water is treated to be less corrosive, but tanks still age. A plumber can check the anode and tell you whether the tank is near the end.
Plumbing and gas permits go through the Building Department at Town Hall, and the plumbing and gas inspector inspects the work. If an oil burner or propane tank is involved, the Fire Department's Fire Prevention Division also has a permit.
Get everyone out and call 911 or your gas company from outside. Don't light anything or flip switches on the way out.
Yes. Talk through your hot water use, venting, gas supply, and fuel. Have the plumber put both options in writing so you can compare them side by side.
