A toilet handles one job well: human waste and toilet paper. Almost everything else that goes down it eventually causes a clog, a backup, or a blocked sewer line. In older Chicago and western suburb homes with aging clay-tile laterals, the wrong flush is one of the most common reasons a homeowner ends up calling a plumber. Here is what should never go down the toilet, and what it does to your pipes when it does.
Never Flush These
- “Flushable” wipes. Despite the label, they do not break down like toilet paper and are a leading cause of clogged lines and sewer backups.
- Paper towels and tissues. They are built to stay intact when wet, so they snag and accumulate in the line.
- Grease, fats, and cooking oil. Liquid going in, solid once it cools, coating the pipe and catching everything else.
- Feminine hygiene products and cotton items. They absorb water and expand, jamming the line.
- Dental floss and hair. They tangle into a net that traps debris.
- Medications. They do not clog, but they contaminate the water supply and should go to a pharmacy take-back program instead.
- Cat litter, diapers, and food. None of it breaks down, and all of it builds up.
Why It Matters More in Older Chicago Homes
Newer plumbing can sometimes pass a minor offender. Older sewer laterals in Lyons, Berwyn, and Cicero cannot. Those clay-tile lines already collect grease and root intrusion at the joints, so a wad of wipes or a buildup of grease is often the final straw that turns a narrowed pipe into a full blockage. What flushes fine in a new build can back up a basement in a hundred-year-old house.
Where It All Ends Up
Items that make it past your home don’t disappear, they burden the municipal system, where wipes and grease combine into the masses that clog public sewers. The EPA explains why only the right things belong in the drain on its trash-free waters resource. Keeping them out of your toilet protects both your line and the system downstream.
What to Do Instead
Throw wipes, hygiene products, and paper towels in the trash. Pour cooled grease into a container and discard it rather than rinsing it down any drain. If grease has already built up in your kitchen line, high-pressure jetting is the most thorough way to clear it.
If Something Already Went Down
If a bad flush has your toilet or drains running slow, a professional drain clearing removes the blockage before it reaches the main line. And if clogs keep coming back after the obvious cause is gone, a camera inspection shows what is really happening inside the pipe.
