Nine Things That Should Never Go Down a Florida Drain
Most clogs are not bad luck. They are the slow result of things going down the drain that never should have. In South Florida, where many homes still run on narrow, scaled cast iron and roots wait at every joint, the margin for error is smaller than in newer plumbing, so what you put down the drain matters even more.
Here are nine common offenders, why each one causes trouble, and what to do instead.
1. Cooking grease, oil, and fat
This is the number one drain killer. Hot grease pours like a liquid and then cools and hardens inside the pipe, coating the walls and catching everything else. In scaled cast iron, it clings even faster. Let grease cool, pour it into a container, and throw it in the trash, never down the drain, even with hot water chasing it.
2. So-called flushable wipes
Despite the label, these wipes do not break down like toilet paper. They stay intact, snag on any rough spot or root, and are a leading cause of main-line clogs. Nothing but human waste and toilet paper should go in the toilet. Put wipes in the trash, flushable or not.
3. Coffee grounds
Grounds do not dissolve. They clump together and settle into a dense sludge, especially in low spots and bellies common in high-water-table areas. Compost them or toss them in the trash.
4. Eggshells and hard food scraps
Eggshells grind into tiny sharp granules that combine with grease into a concrete-like paste, and fibrous scraps tangle. A garbage disposal does not change this, it just makes the pieces smaller before they cause the same problem.
5. Starchy and fibrous foods
- Rice and pasta swell with water and turn to paste
- Potato peels form a gluey mass
- Celery, corn husks, and onion skins have stringy fibers that tangle and catch
6. Hair
Hair binds with soap scum into stubborn clogs, the top cause of slow bathroom drains. A cheap drain screen on every tub and shower stops the vast majority of it. Empty the screen into the trash, not the drain.
7. Harsh chemical drain cleaners
It is counterintuitive, but caustic drain cleaners can do more harm than good. They generate heat and sit against pipe walls, accelerating corrosion in aging cast iron, and they rarely clear a real clog, leaving hazardous liquid standing in the line for whoever works on it next. Mechanical clearing or jetting is safer and more effective.
8. Paint, solvents, and chemicals
Paint, paint thinner, and household chemicals do not belong in the drain, they coat pipes, harm the sewer system, and are an environmental problem. Take them to a household hazardous waste drop-off instead.
9. Paper towels, cotton products, and dental floss
Paper towels and cotton balls do not break down like toilet paper, and dental floss is a thin net that catches other debris and even snags on roots. All of it belongs in the trash. In older Coconut Creek, Tamarac, and Lauderhill lines especially, these are exactly the items that turn a narrow pipe into a blocked one.
A garbage disposal doesn't make it safe
A disposal is the most misunderstood fixture in the kitchen. It grinds food into smaller pieces, but it does not change what those pieces do downstream — grease still hardens on the pipe wall, and starchy or fibrous scraps still swell and knit into a plug well past the disposal.
Think of the disposal as a last resort for the scraps that get past you, not a license to send everything down the sink. Scrape plates into the trash or compost first, keep grease out entirely, and run plenty of cool water. The disposal will last longer and your kitchen line will clog far less often.
Key takeaway: Grease, flushable wipes, coffee grounds, eggshells, starchy foods, hair, chemical cleaners, paint, and paper products all cause clogs; keep them out of the drain, especially in older cast iron lines.
