Plumbing in Medway — what to know

Rebates & incentives

Medway is in Eversource electric territory, so homeowners qualify for the full Mass Save program. The plumbing-relevant incentive is the heat-pump water heater (HPWH) rebate ($750 per unit, whatever the old tank burned), with a free Mass Save Home Energy Assessment as the unlock.

Because natural gas serves much of Medway, plenty of homes run gas water heaters today; switching to an HPWH (which the rebate targets) means going electric, so confirm your panel can carry it. For homes still on electric tanks, the swap is straightforward. Medway's housing isn't old enough for widespread lead service lines, but pre-1986 homes should still have a plumber confirm supply-line material.

Permits in Medway

Massachusetts requires a licensed plumber and a plumbing permit for water heaters, repiping, drain and sewer work, and rough-ins, filed through the Medway building department. Gas work needs a separately licensed gas fitter and a gas permit — relevant here given the town's gas service. Projects near the Charles River or the town's wetlands can trigger Conservation Commission review. Standard interior water-heater and fixture work moves through permitting in a few business days.

A plumbing or gas permit in Medway is filed with the town’s plumbing and gas inspector; see the Medway Building Department’s contact, portal and who pulls the permit on permits.llc.

Typical project cost

Medway sits in the eastern-Massachusetts / MetroWest cost band, above central and western MA but below Boston proper. A standard tank water heater typically runs $1,900–$3,300 installed; a heat-pump water heater $2,800–$4,800 before the Mass Save rebate; a tankless unit $4,500–$7,000. Gas-fitting work adds the cost of a licensed gas fitter. Repiping or full-bath rough-ins in older split-levels run higher when access is tight or finishes need protecting.

About Medway homes

Medway is a Norfolk County town of about 13,164 residents across roughly 4,598 housing units, tucked along the Charles River on the MetroWest–Milford line. The median home is around 50 years old, a mix of 1960s–70s subdivisions and newer infill, with town water and sewer serving most of the developed core.

Most plumbing work here is the suburban steady-state: replacing water heaters in maturing split-levels and Colonials, upgrading 50-year-old fixtures and supply lines, and gas-fitting work since natural gas reaches much of the town. The river and wetland corridors mean some lower-lying neighborhoods deal with sump and groundwater management too.

Common questions — Plumbing in Medway

Does Mass Save cover heat-pump water heaters in Medway?
Yes. Medway is Eversource territory, so the Mass Save heat-pump water heater rebate applies ($750 per unit, whatever the old tank burned) after a free Home Energy Assessment. Note an HPWH is electric, so you'd be switching off a gas tank if you have one.
I have natural gas in Medway. Should I stick with a gas water heater?
It depends on your goals. Gas tanks are cheaper to install, but a heat-pump water heater qualifies for the Mass Save rebate and costs less to run. A plumber can confirm whether your electrical panel supports the switch.
Do I need a separate license for gas work in Medway?
Yes. In Massachusetts, gas piping and gas appliance hookups require a licensed gas fitter and a gas permit, separate from the plumbing license and permit. Many plumbing firms in Medway carry both licenses in-house.
Do I need a permit to replace a water heater in Medway?
Yes. Water-heater replacement requires a plumbing permit and a licensed plumber through the Medway building department; a gas unit also needs a gas fitter and gas permit. Your installer normally pulls the permit for you.
My Medway basement floods near the Charles River. Can a plumber help?
Yes. A plumber can install or service a sump pump and battery backup to manage groundwater, which is common in lower-lying neighborhoods near the river and wetlands. It's separate from your water-supply plumbing but often handled by the same contractor.
