Hanover · Water Heaters
No hot water, a leaking tank, or rusty water from the hot side in Hanover? Call or send a request to reach an independent plumber who works on Hanover water heaters.
Hanover, Massachusetts
Hanover's tap water starts as groundwater from nine town wells, and the Town says iron and manganese are common in it. Its treatment plants remove most of both, but 1 to 2 percent typically passes through and can settle in the distribution system. Sediment of any kind tends to collect at the bottom of a tank water heater, where it can make the burner work harder and the tank rumble as it heats.
If you smell gas near the heater, leave the house and call 911 or Eversource from outside before doing anything else. If the tank is leaking, close the cold-water valve above it only if you can reach it without standing in water, and keep clear of any wiring.

Sediment taking up space in the tank, or a failed element on an electric unit, can shorten every shower.
Noise as the burner fires often means water is boiling up through a layer of sediment on the tank bottom.
If the cold taps run clear and the hot taps run brown, the tank is the likely source rather than the town mains.
A wet drain pan or puddle under the tank can be a loose fitting or the start of a failing tank, and it needs a look soon.
Local knowledge
Water quality, fuel supply, and fire department rules all come into play on a Hanover water heater job.
Iron And Manganese
The Hanover Water Department says a small share of iron and manganese passes through its plants and can settle in the pipes. Brown or black specks at the hot tap, or a tank that pops as it heats, are good reasons to ask a plumber about flushing or a sediment check.

Gas And Electric
State utility listings name Eversource (EGMA) as Hanover's gas company and National Grid as its electric company, and both companies sponsor Mass Save. Before choosing a replacement, ask a plumber whether a heat pump or high-efficiency model fits a current Mass Save offer.

Propane Units
The Hanover Fire Department's Fire Prevention Division requires an FP 06 form for propane storage and installation. If your water heater runs on propane, ask the plumber how the tank and gas line paperwork will be handled with the fire department.

Right now
These steps keep you safe and limit damage until a plumber can look at the unit.
A gas or propane odor means get out and call 911 or your gas supplier from outside. Leave light switches alone and don't attempt to relight the pilot.
The valve on the cold line above most tanks stops more water from entering. Turn it only if you can reach it from dry footing.
If water has reached an electric heater's wiring or nearby outlets, stay out of the area and leave the power to a professional.
Run a cold tap briefly. Clear cold water with brown hot water points to the tank, while discolored water everywhere may be sediment in the mains that the Water Department can explain.
What to expect
A plumber will usually check the fuel supply, venting, relief valve, and thermostat or burner, then look at the age and condition of the tank. In Hanover, expect questions about sediment, since minerals from the town's groundwater can build up in older tanks.
Replacement generally calls for a permit. Hanover's Building and Inspectional Services handles plumbing permits through its OpenGov portal, and its plumbing and gas inspector checks the installation. Propane units also involve the fire department's FP 06 form.
When replacement makes sense, the plumber should go over tank, tankless, and heat pump options, how much hot water your household uses, and where the new unit can sit. Census estimates put Hanover at 2.94 people per household, a starting point for sizing that you can adjust for your own family.
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.
Look up the plumber on the state's occupational license lookup. Gas work in Massachusetts needs a gas fitter license, so confirm that whoever connects a gas unit holds one.
The plumber should file the Hanover permit and schedule the inspection rather than asking you to do it.
If you're considering a heat pump water heater, ask whether the model qualifies for a current Mass Save offer and who handles the paperwork.
Have each quote list the unit, venting, removal of the old tank, and the permit so you're comparing the same job.
Costs
Repair versus replacement is the first fork. A failed thermostat or igniter is a smaller job than a tank leaking from the bottom. For replacements, the fuel type, venting changes, tank size, and the route into the basement all shape the price.
Ask for a written estimate that covers the unit, labor, permits, disposal, and any gas or vent work. If sediment is part of the problem, ask whether regular flushing or a filter would extend the new tank's life, and what that would add.

The Town says small amounts of iron and manganese pass through treatment and can settle in the mains. If only the hot side is discolored, sediment in the water heater is a likely cause, and a plumber can flush or inspect the tank.
State utility listings name Eversource as Hanover's natural gas company. Some homes use propane instead, which comes with its own fire department paperwork. Either way, leave and call 911 from outside if you smell gas.
In most cases, yes. Hanover handles plumbing permits through Building and Inspectional Services and its OpenGov portal, and the plumbing and gas inspector checks the work. Your plumber should file it.
National Grid and Eversource are Mass Save sponsors, and Mass Save lists its residential offers online. Offers change, so check the current list and ask your plumber whether the model you're considering qualifies.
