Flushable is not the same as breaks down
Toilet paper is designed to fall apart in water within seconds. Most wipes are made of tougher fibers designed to stay intact while you use them. They pass through the toilet easily, but in the pipe they stay mostly whole, catching on joints, rough spots and roots. Several wipes together twist into a rope that grabs paper and grease. In a sewer lateral with any imperfection, that rope eventually blocks the line.
Plumbers pull wads of wipes out of main lines constantly, and many cities have run campaigns asking residents not to flush them because they clog pumps and screens at treatment plants too.
Where wipes cause trouble
| Location | What happens |
|---|---|
| Toilet trapway | Rarely; wipes usually pass through |
| Branch line | Wipes catch at fittings and build up |
| Main line and lateral | Most common: wipes snag on joints, roots or sags |
| Septic systems | Wipes don't break down and fill the tank faster |
| City pump stations | Wipes tangle pumps and screens |
Signs wipes are building up
- Toilets flush slowly or need two flushes
- Gurgling from drains when a toilet flushes
- A floor drain or tub takes water when toilets run
- A plumber pulls a wad of fiber off the cable
What to use instead
- Keep a small lidded trash can in every bathroom
- Use toilet paper for anything going down the toilet
- Put baby wipes, makeup wipes and cleaning wipes in the trash
- Teach children and guests the rule with a small sign if needed
If wipes have already clogged the line
A plumber clears a wipes clog with a cable or jetter, usually from the main cleanout. The camera often shows why wipes stopped where they did: a root at a joint, a sag that holds water, or an offset that catches debris. If the line is otherwise sound, keeping wipes out of it is usually enough. If there's a structural issue, wipes will keep catching there until it's fixed.
Wipes and septic systems
On a septic system, wipes add solids that bacteria can't break down. They float or settle in the tank, take up space and can clog the outlet or drain field. Homes on septic should keep wipes out of toilets entirely, and should pump the tank on schedule.
