Plumbers in Illinois

Lead, and what to do about it

Illinois carries a plumbing legacy that no other state does at the same scale. Chicago’s municipal code required lead service lines, the pipe between the water main and the meter, right up until the federal ban in 1986. The city’s own estimates put the number still in the ground in the hundreds of thousands, more than any other American city.

For a homeowner the useful part is that identification is easy. Find where the water enters the basement, ahead of the meter, and scratch the pipe with a coin. Lead is dull grey and soft, scratches to a bright silver, and a magnet will not stick to it. Copper scratches copper-coloured. Galvanized steel is threaded and magnetic. If it is lead, the city has replacement programmes, and the portion on your side of the meter is work a plumber can do.

The basement, the storm and the sewer

The second defining fact about Illinois plumbing is that almost every house has a basement, which puts the floor drain and the laundry below the level of the sewer in the street. In Chicago and the older suburbs, that sewer is a combined system: storm water and sewage in the same pipe. When a summer storm drops more water than the system can move, the pressure relieves through the lowest connected opening in the neighbourhood, and that is somebody’s basement floor drain.

Nothing about that is a clogged drain, and cleaning it changes nothing. The equipment that matters is a backwater valve on the house drain, which closes when the sewer pushes back, and a sump pump with a backup for the groundwater side. Illinois sump pumps fail for three reasons in particular: the discharge line freezes, the float jams, or the power goes out during the exact storm that made the pump necessary.

Clay that moves all winter

Illinois sits on glacial clay that holds water and moves as it freezes and thaws, and a Chicago winter provides plenty of both. That movement works on buried pipe all season, pulling joints apart in clay tile laterals and creating bellies, low spots where waste settles instead of flowing.

This is why so many Illinois homeowners have a sewer line rodded every year and never fix the problem. Rodding clears what is inside the pipe. It does not close the joints that roots came through, and it does not level a belly. A camera inspection tells you whether you are dealing with roots, a crack, or a sag, and lining or replacing the lateral is what stops the annual visit.

Water, and who may work on it

Chicago drinks Lake Michigan water at roughly eight grains per gallon, which is moderate. It scales a water heater over years rather than months, so an annual flush is usually enough and a softener is a preference. Downstate communities drawing groundwater run harder, sometimes considerably, and there a softener is a straightforward investment.

One thing worth knowing as a homeowner: Illinois licenses plumbers at state level through its Department of Public Health, which is stricter than the municipal patchwork used in several neighbouring states, and Chicago adds requirements of its own. For any permitted work, that licence is what lets the permit be pulled and the installation inspected. Every plumber we dispatch in Illinois holds it.
