What's actually causing this
Drain clogs form when debris accumulates in the P-trap or the drain pipe below it. In bathrooms, hair and soap are the main culprits. In kitchens, grease and food particles solidify over time and narrow the pipe.

Step-by-step fix
-
1
Try the barbed drain tool first
Insert a plastic hair clog remover into the drain and twist it to grab the clog. Pull it out slowly — most bathroom clogs come out in one motion.
-
2
Plunge the drain
Cover the drain with a cup plunger, ensuring a seal. Plunge vigorously 10–15 times. Run hot water to check flow.
-
3
Baking soda and vinegar flush
Pour half a cup of baking soda down the drain, followed by half a cup of white vinegar. Wait 15 minutes, then flush with boiling water.
-
4
Remove and clean the P-trap
Place a bucket under the curved pipe beneath the sink. Unscrew the slip joints by hand (or with pliers) and pull out the P-trap. Clean it out and reinstall.

5
Run water and test
Run hot water for 2 minutes to ensure full flow is restored. Watch for any slow drainage, which may indicate a deeper blockage.
In Chicago, tap water is very hard (280–350 ppm). Chicago's water is among the hardest in major U.S. cities, sourced from Lake Michigan. Heavy mineral deposits accumulate on fixtures and inside pipes. Water softeners are extremely common. Hard water accelerates water heater failure.
Plumbers in Chicago typically charge $110–180/hr. Most homeowners budget $800–2,500 for common repairs like fixture replacement, drain clearing, or valve repairs.
Illinois requires journeyman and master plumber licenses. Chicago requires city permits and inspections. Homeowner exemptions are limited to minor repairs on owner-occupied properties.
Pre-1950s homes commonly have galvanized steel piping with severe corrosion issues. Cast-iron drain stacks are typical and may need replacement. Many homes have had copper installed over decades. Water softener installation is almost universal.
DIY in Chicago: Chicago's licensing requirements are moderate. Homeowners can perform some plumbing and electrical work on their own homes, but city inspections are strict. Most people hire contractors for permits and anything beyond cosmetic repairs.
- Multiple drains in the house are slow at the same time — this indicates a main line clog.
- You hear gurgling from other drains when you flush the toilet.
- You smell sewer gas — this is a health hazard requiring immediate attention.
- The drain has been cleaned but keeps re-clogging within days.
