Plumbing in Bath, Maine
Family-owned, licensed and insured plumbing for Bath homes, from our base in Augusta.
Your local plumber in Bath, Maine
Bath sits directly on the tidal Kennebec River and is home to Bath Iron Works, the shipyard that’s earned the city its "City of Ships" nickname since 1884. It has the oldest housing stock of any town we serve — well over half built before 1940 — inside a historic district that runs right down to the waterfront, so old pipe is the rule here, not the exception.
Plumbing in Maine's oldest shipbuilding city
Bath’s median home was built in 1938, and 58% of the city’s housing predates 1940 — the oldest stock of any town on our list. Homes like these routinely have galvanized supply lines, cast-iron drains and early copper behind the walls, all of it original enough to be past due. Our pipe repair and repiping service replaces failing sections with copper or PEX and pressure-tests the line before the wall goes back up.
Exterior work on a building inside the Bath Historic District needs Planning Board review, though the city says it is often completed administratively in as little as three days. That review is about the outside of the house, not what happens behind the walls, so it rarely slows down a bathroom or kitchen plumbing job.
Tidal water, city sewer and combined-sewer areas
The Bath Water District has supplied the city from Nequasset Lake in neighboring Woolwich for more than a century. Wastewater is handled by the city’s own Public Works department, whose treatment plant averages about 2 million gallons a day across 13 pump stations, discharging to the tidal Kennebec. Part of Bath’s sewer system uses combined sewers that can overflow in heavy rain, which is one reason the city cares about keeping stormwater and groundwater out of the sanitary side.
That combined-sewer detail matters directly for sump pump installation: a sump pump has to discharge outside, never into a sewer cleanout, in a city already managing overflow risk. For flooded or failing supply lines near the water, our emergency plumbing repairs service responds quickly.
Heat, hot water and permits in Bath
Fuel oil heats about 47% of Bath homes, with propane and electricity each covering roughly a fifth, and Maine Natural Gas reaches parts of the city as well. That mix means a water heater replacement can go several directions — oil-fired indirect, propane, electric or hybrid heat-pump — and our water heater installation team will lay out which fits your setup.
Plumbing permits in Bath go through the Code Enforcement Office at 55 Front Street using the state’s standard Internal Plumbing application, with inspections required at several stages of the work. Every job, from a new construction rough-in to routine drain cleaning, starts with a free estimate and an upfront price. See all of our service areas, including neighboring Topsham.

Codes & Permits for Plumbing in Bath
In Bath, plumbing permits come from the Local Plumbing Inspector at the City of Bath Code Enforcement Office (55 Front St., Bath, ME 04530, (207) 443-8330). With 8,815 residents, Bath is required to enforce the Maine Uniform Building and Energy Code (MUBEC). Home to Bath Iron Works, a major shipyard that has built Navy vessels since 1884, giving Bath its "City of Ships" nickname.
- The EPA's Lead and Copper Rule Revisions required every U.S. community water system to complete an initial inventory of lead, galvanized-requiring-replacement, and unknown-material service lines by October 16, 2024; the follow-on Lead and Copper Rule Improvements, finalized October 8, 2024, requires full replacement of remaining lead lines within 10 years. epa.gov
- The Maine Plumbers' Examining Board (within the Office of Professional and Occupational Regulation, Department of Professional and Financial Regulation) licenses plumbers statewide and maintains the plumbing rules and laws (Title 32, Chapter 49); day-to-day permit issuance and inspection for a given town is carried out locally by a Local Plumbing Inspector (LPI), who is often the same person as the municipality's Code Enforcement Officer. maine.gov
How RJC Plumbing Handles Plumbing in Bath
- Bath's housing stock runs old enough (median year built 1938) that a plumbing job often turns up a mix of pipe eras in the same house — we tell you plainly which sections are sound and which ones are due.
- Most Bath addresses run on Bath Water District (BWD) water, drawn from Nequasset Lake (a 21-square-mile watershed mainly in Woolwich, extending into Dresden and Wiscasset); BWD's source for over 100 years — everything from that meter into the house, fixtures included, is ours to service.
- We file for a permit at the City of Bath Code Enforcement Office whenever the work calls for one, to the current 2021 Uniform Plumbing Code.
