What shapes water heater trouble in Weymouth
A $40 gas permit, and the rest of the fees
Weymouth's fee schedule, in effect since July 1, 2024, lists a gas water heater at $40. Plumbing permits are a $20 application fee plus $20 a fixture, a gas test costs $20 when it's required, and a failed or missed inspection means a $100 reinspection fee. An inspection after hours costs $200. State rules require a permit before plumbing or gas work is installed, replaced or repaired, and the licensed plumber or gas fitter pulls it.
About 33% of Weymouth households rent, and about 14% of homes are in buildings with 50 or more units. If you rent, the water heater is usually the landlord's to fix, so report it to them in writing first. The median home was built in 1964, and about 22% date from before 1940.
Two treatment plants, and who to call
The town's 2025 water report says Weymouth runs two treatment plants. The Great Pond plant treats water from Great Pond, topped up from the South Cove of Whitman's Pond, and can produce up to 8 million gallons a day. The Arthur J. Bilodeau plant treats groundwater from five wells in the Mill River Aquifer. Both add phosphoric acid for corrosion control, and the water reaches 16,773 customers through more than 237 miles of pipe.
For leaks at the meter, main breaks or water quality questions, the Water Department is at 781-337-5100, Monday through Friday, 7:30 a.m. to 3:30 p.m. After hours, on weekends and on holidays, the town says to call the police dispatcher at 781-335-1212. A leaking water heater inside the house is a plumber's job, so shut off the cold supply valve on top of the tank while you wait.
Heat pump water heaters and Mass Save
About 46% of Weymouth homes heat with gas, 27% with oil and 24% with electricity. The town lists National Grid for both gas and electricity, and both are Mass Save sponsors. Mass Save offers $750 on an ENERGY STAR heat pump water heater, or $1,500 on a split system, when it replaces an existing electric, propane, gas or oil water heater. Its own example puts an average installed cost at $3,200, or $2,450 after the rebate.
Mass Save notes these units pull heat from the surrounding air, so they work best in a basement or utility room and lose efficiency in a cramped closet. It also notes that the federal tax credit for heat pumps ended for purchases after December 31, 2025. If your old tank sits in a closet, ask the plumber about space and clearance before you choose one.
