Your toilet is essential, but it’s not designed to handle anything beyond the basics. Flushing the wrong items can lead to severe clogs, plumbing damage, and expensive repairs. Even products labeled “flushable” can harm pipes and wastewater systems. Understanding what not to flush helps protect your plumbing and your wallet.
Snapshot: Toilet Flushing Hazards
| Item | Why It’s a Problem | Potential Cost | Local Insights |
|---|---|---|---|
| Paper Towels | Don’t dissolve; create clogs | $150–$500 | Frequent in Houston households |
| Wet Wipes | Resist breaking down | $200–$600 | Even “flushable” wipes cause problems |
| Condoms | Can tangle and block pipes | $250–$700 | Found in wastewater facilities |
| Feminine Products | Expand in water; block pipes | $300–$800 | Major cause of residential clogs |
| Dental Floss | Wraps around debris inside pipes | $100–$400 | Combines with other debris |
| Diapers | Expand heavily; cause severe clogs | $400–$900 | Rare but extremely problematic |
| Medications | Contaminate water; non-biodegradable | $50–$300 | Requires take-back programs |
The Rule of the Three P’s
Only flush: Pee, Poop, and Paper. Everything else can damage pipes or wastewater systems.
1. Paper Towels
Paper towels don’t dissolve like toilet paper. Flushing them leads to slow drains or full blockages. Always throw them in the trash.
2. Wet Wipes
Even “flushable” wipes don’t break down easily. They combine with grease and debris to create stubborn clogs. Keep a trash bin nearby and avoid flushing them.
3. Condoms
Condoms are durable and flexible, making them capable of causing major blockages. Dispose of them in the trash to avoid plumbing disasters.
4. Feminine Products
Pads and tampons expand when wet. Their absorbent material makes them especially dangerous for plumbing. Always throw them in a trash bin.
5. Dental Floss
Floss doesn’t dissolve. It tangles with debris, forming rope-like blockages inside pipes. Dispose of floss in a trash bin to prevent costly repairs.
6. Diapers
Diapers expand dramatically in water and can block an entire pipe. Never flush them under any circumstance.
7. Medications
Medications contaminate water supplies and do not break down naturally. Take them to a pharmacy’s take-back program instead of flushing.
