Water Line Repair and Replacement in Chicago, IL
Chicago has more lead water service lines than any other US city, because the city's code required lead for service lines until 1986. Replacing one runs from the water main to the meter and is permitted through the city. Check the Department of Water Management's replacement programs before paying for the work yourself.

What is different about water line repair and replacement in Chicago?
If your home or two-flat was built before the late 1980s and the service has never been replaced, assume it may be lead until you have checked. The pipe near the meter is the place to look, and the city keeps a record of known service line materials and offers free water testing.
A leak or break on a lead service is usually the moment to replace it entirely instead of repairing a section, since cutting into lead pipe can release particles. The city's programs have eligibility rules that change over time, including ones tied to leaks and breaks, so ask what applies to your address before signing a contract. Chicago winters also mean the line is buried deep, which makes the excavation or boring a larger part of the job than in warm climates.

Licensing and permits for water line repair and replacement in Chicago
Chicago adopts and enforces its own plumbing code, which has historically been stricter about pipe materials than the codes used in most suburbs, and plumbers working in the city must hold a City of Chicago plumbing license. Permits come from the Department of Buildings. Ask for the license number, and ask whether the materials quoted are approved for use in the city.
Keystream Plumbing is a referral service. We do not perform plumbing work or hold a contractor license. The independent plumber you are connected with is responsible for licensing, permits and the work itself.

Water Line Repair and Replacement questions from Chicago
Does Chicago replace lead service lines for free?
The city runs several replacement programs, and some cover the cost for homeowners who meet eligibility rules. The programs and their conditions change, so check the Department of Water Management's current information for your address before hiring a plumber.
My water line broke. Do I have to replace all of it?
If the line is lead, full replacement is strongly recommended and may be required under city rules when a lead line is disturbed. Ask the plumber and the Department of Water Management what applies, and whether a break makes you eligible for a city program.
