Water Heater Repair in Hanson, MA
Hanson is one of the few towns split between two gas companies, Eversource and National Grid. It matters if you ever smell gas. If your water heater has stopped or is leaking, call and get a plumber out.
What shapes water heater trouble in Hanson
Which gas company is yours?
The state's gas provider map lists both Eversource and National Grid for Hanson. Your gas bill shows which one serves your street. Keep that number handy: if you smell gas, leave the house, call 911 from outside, then call your gas company.
Crystal Springs wells
A 2021 state environmental filing describes Hanson's water system as supplied by four groundwater wells in the Crystal Springs Wellfield. Well water leaves some sediment in any tank over time, so a yearly flush is a good habit.
Gas, oil and propane
About 51% of Hanson homes heat with gas, 37% with oil and 5% with propane. About 89% are owner-occupied, so when a heater is near the end, the choice of what replaces it is yours. A plumber can lay out the options for your fuel.
Safe steps for Hanson homes
- Leaking? Close the cold water valve on top of the tank.
- Turn off the gas valve or the breaker for the heater.
- Gas smell? Eversource and National Grid both serve parts of Hanson. Leave the house, call 911 from outside, then call the gas company on your bill (National Grid: 1-800-233-5325).
