Plumbing help in Dearborn, MI
Older PipesFrozen Pipes
Dearborn sits along the Rouge River, and its brick bungalows and colonials (median home from 1950) mostly have finished basements. That makes basement flooding, floor-drain backups and old clay sewer connections the city's defining plumbing concerns, along with lead service line replacement tied to its water main program.

What Dearborn homeowners call plumbers about
- Sewer Backup
Finished basements along the Rouge River watershed are vulnerable when heavy rain overloads sewers.
- Sewer Camera Inspection
Old clay connections under 1940s–50s bungalows crack and collect roots; a camera shows where before any digging.
- Water Line Repair
Lead service lines are being replaced as the city renews its water mains.

Dearborn plumbing questions
Which GLWA plants serve Dearborn?
Dearborn's water comes from GLWA's Springwells plant on Warren Avenue and its Southwest plant in Allen Park.
When will Dearborn replace my lead service line?
The city is pairing lead line replacement with water main work over about 20 years. Ask the city whether your street is scheduled.
How can I protect a finished Dearborn basement from flooding?
A backwater valve on the main sewer line, a sump pump with battery backup and keeping floor drains clear are the core protections. Store valuables off the floor.
Should I scope the sewer before buying a Dearborn bungalow?
Yes. Many homes from the 1940s and '50s have original clay connections, and a camera inspection is far cheaper than an excavation surprise.
How do I check a Dearborn plumber?
Verify the license with Michigan LARA's Bureau of Construction Codes.
