Hanover · Plymouth County
Septic backup, a slow drain, or a wet basement in Hanover? Call or send a request and you'll be connected with an independent plumber who serves Hanover homes.
Hanover, Massachusetts
Two facts shape almost every plumbing job in Hanover. The town has no municipal sewer outside a few special treatment facilities, so most homes send their wastewater to a private septic system, and the drinking water comes from town wells rather than a reservoir. A plumber who works here plans around both.
If sewage is coming up through a floor drain or water is spreading toward the electrical panel, get everyone out and call 911 from outside before you think about repairs. For a split pipe you can reach safely, close the main shutoff, then call or send a request to reach an independent plumber who serves Hanover.

Local knowledge
These local conditions come up again and again on Hanover plumbing calls.
Septic, Not Sewer
The town's 2021-2022 Housing Production Plan says Hanover has no municipal sewer service apart from special treatment facilities in a few spots. The pipe from your foundation to the tank, and the tank itself, are part of your property, so what looks like a main-line clog may really be a full or failing septic system.
Town Well Water
Hanover pumps groundwater from nine wells and treats it at the Pond Street, Beal, and Broadway plants. The Town says iron and manganese are common in that groundwater and that 1 to 2 percent typically passes through treatment and settles in the distribution system, which can show up as discolored water or grit in a water heater.

Service Line Inventory
Hanover's 2025 water quality report says the service line inventory found no lead lines, no galvanized lines needing replacement, and none of unknown status. If lead still worries you, the line from the street is unlikely to be the cause, so ask a plumber about older faucets and soldered joints inside the house.
River Flooding
The town's 2016 hazard mitigation plan rates flooding as a high-frequency hazard, and a June 2023 draft update says every stream and brook in the Drinkwater River system has potential flood hazard areas. Basements near those waters are where sump pumps, raised equipment, and a known shutoff matter most.

Housing Age
The Housing Production Plan counts 635 of Hanover's 5,038 housing units, or 12.6 percent, as built in 1939 or earlier, and places another 36 percent in the 1950s and 1960s. Houses from either era can still have original drain and supply piping that a plumber should check before tying in new fixtures.
Services
Here's how each common job tends to look in a town of septic tanks, well-sourced town water, and flood-prone brooks.
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.

Hanover's Building and Inspectional Services department at Town Hall issues plumbing permits through the Town's online OpenGov portal, and the plumbing and gas inspector checks the work. Your plumber normally files the application. Source
Septic systems in Hanover are regulated by the Board of Health under the state's Title 5 rules. If a backup turns out to be the tank or leach field, ask whether a septic contractor and a Health Department filing will be needed. Source
Ask for labor, parts, the permit, and any trenching or restoration as separate lines, along with how the plumber will price surprises once a wall or yard is opened.
Costs
On a Hanover lot, the distance from the house to the septic tank, the depth of the pipe, and what sits on top of it, such as a driveway or patio, drive the cost of drain and line work. Inside the house, the age of the piping and how finished the basement is matter most.
Ask for a written estimate before work starts and check whether it covers the permit and inspection. If the job may involve the septic system, ask which part the plumber handles and which needs a septic contractor, so the two quotes don't overlap or leave a gap.
Income-eligible owner-occupants can apply to the Town's Affordable Septic Program, which offers partially forgivable loans to repair or replace a septic system or cesspool. Confirm the program's current terms with the Town before you sign a contract.
Neighborhoods and nearby
Plumbers who serve Hanover work across its villages, from Assinippi and North Hanover to Hanover Center, Four Corners, and South Hanover. Many also take calls in nearby Pembroke, Norwell, Hanson, and Rockland.

The type of problem, the age and material of the pipes, how hard they are to reach, and whether a permit or septic work is involved. A Hanover plumber can give you a written estimate after seeing the job. Ask what's included and how hidden problems will be priced.
Close the main shutoff if you can reach it without standing in water. If water is near outlets or the panel, leave and call 911. When you call us, you'll be connected with an independent local plumber, and how soon they can come depends on their schedule.
Building and Inspectional Services at Hanover Town Hall issues building, electrical, and plumbing permits through the Town's online OpenGov portal, and a plumbing and gas inspector reviews the work. Expect the plumber, who should carry a Massachusetts license, to file that permit for you.
Mostly no. The Housing Production Plan says the town has no municipal sewer apart from special treatment facilities in a few locations, so most homes use septic systems regulated by the Board of Health. Keep grease, wipes, and harsh chemicals out of your drains, since they all end up in the tank.
The 2025 annual water quality report says the inventory found no lead service lines and no galvanized lines needing replacement. In that year's lead sampling, 3 of 120 sites were above the 15 ppb action level with no violation, so plumbing inside a house can still matter. A plumber can look at older fixtures and joints.
