Water line repair in Chicago, IL

The water service line runs from the curb stop near the street to your house, buried below the frost line. A leak shows up as a soggy patch in the yard, low pressure throughout the house, or a meter that never stops. Repair means finding the leak, then fixing that spot or replacing the line.

Water line repair in Chicago: what's different

Many older Chicago homes are served by lead service lines, and the city has a replacement program. Leaks in the service line show up as low pressure, a wet spot near the curb or a higher bill.

A plumber locates the leak and repairs or replaces the line. Permits come from the Chicago Department of Buildings, and the Department of Water Management handles the main.

Chicago's deep frost line means service lines are buried deep, which affects how repairs are made and what they cost.

Other Chicago conditions that affect plumbing

  • Basement flooding: Combined sewers can back up during heavy storms; overhead sewers, backwater valves and sump pumps are common upgrades.
  • Frozen pipes: Sub-zero cold freezes pipes along exterior walls and in unheated porches and garages.
  • Lead service lines: Many older Chicago homes are served by lead service lines, and the city has a replacement program.
  • Deep Tunnel: Chicago's Tunnel and Reservoir Plan (Deep Tunnel) stores stormwater to reduce flooding, but intense storms can still overwhelm local sewers and push water into basements, which is why overhead sewers and backwater valves are popular upgrades.

Water line repair questions in Chicago

Should I replace my Chicago lead service line?

Yes. Lead service lines can leach lead into drinking water. Check whether the city's replacement program covers your home.

Do I own the water line to my house?

Usually from the curb stop (a shutoff near the property line) to the house. The utility owns the main and the connection up to the curb stop. Your water provider can confirm the boundary for your address.

How deep is the water service line?

It's buried below the local frost line, which ranges from a foot or less in the Deep South to 5 feet or more in the northern states. Exact requirements are set by each water provider and building department.

What are the signs of a broken water service line?

A wet or sunken strip of yard between the street and the house, low pressure at every fixture, and a meter that moves when everything is off.
