Drain cleaning in Chicago, IL
If one fixture is slow, the clog is usually in that fixture's branch line. If several drains back up at once, or the basement floor drain fills when you run the washer, the main sewer line is blocked and needs a larger cable or a jetter.

Drain cleaning for Chicago homes
Kitchen drains clog with grease and food. Bathroom drains clog with hair and soap. Main lines in older neighborhoods clog with roots that grow into clay pipe joints. Each needs a different tool, so the first job is figuring out which one you have.

Local conditions
Drain cleaning in Chicago: what's different
Chicago's older homes have cast-iron drains and clay sewer lines that collect roots and grease. Main-line clogs often show up at the basement floor drain, sometimes mistaken for storm flooding.
A plumber clears the line and recommends a camera inspection if the clog returns. Plumbing work must be done by licensed plumbers registered with the city.
Heavy grease from older kitchen lines in two-flats is another common cause.

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.
How drain cleaning works in Chicago

- 2
Clear it
A hand auger, a machine cable or a hydro jetter is used, sized to the pipe.
- 3
Verify flow
Water is run through the line to confirm it drains at full speed.

Why is my basement floor drain backing up?
When water comes up through the basement floor drain, the main sewer line is usually blocked between the house and the street. Stop using water upstairs, then call a plumber to clear the main line. If it happens more than once, a camera inspection shows the cause.

Should you get a sewer scope before buying a home?
For homes built before about 1980, or with large trees in the front yard, a sewer scope is worth it. A standard home inspection doesn't look inside the sewer line, and in most U.S. cities the buyer will own that line, often all the way to the main.
Emergencies
Sump pump not working? Causes and fixes
Check power first, then the float: if it's stuck against the pit wall the pump won't start. A pump that runs but doesn't empty the pit often has a frozen or clogged discharge line or a stuck check valve. If the pit is about to overflow, call right away.
