How a Pipe Leak Happens
- Supply line — pressurized water inside the wall
- Shutoff valve — closing it stops flow to the leak

Plumber in South Portland: What's Different Locally
South Portland sits on Portland Harbor and overlooks Casco Bay with a working waterfront, giving coastal/salt-air exposure (Wikipedia). South Portland’s public water comes from Portland Water District, drawn from Sebago Lake; homes outside that service area rely on a private well, which changes how a water problem gets diagnosed. South Portland’s public sewer runs through South Portland Water Resource Protection Department — outside that service area, drainage goes to a private septic system instead.

Plumber in South Portland, ME FAQs
Do you offer plumbing service in South Portland, ME?
Yes. South Portland is part of our Cumberland County service area, and J&R Mechanical Services handles plumbing service for homes throughout the area. Call (207) 902-8899 or book online to schedule.
How do I keep my pipes from freezing in cold weather?
Insulate any line that runs through an unheated basement, crawlspace, or exterior wall, keep the thermostat at 55°F or higher when away, and open cabinet doors under sinks on cold nights. If a pipe has already frozen, shut off the main and call — thawing it wrong is how pipes burst.
Do you work on older galvanized and cast-iron plumbing?
Yes. We regularly replace corroded galvanized supply lines with PEX or copper and repair cast-iron drains. We tell you when a spot repair is fine and when a section has reached the end of its life.
