There is no exact amount of toilet paper that is too much for every toilet. In general, a large wad sent down in one flush is more likely to cause a clog than the same amount flushed in smaller batches.
How much a toilet can handle depends on the toilet, the type of paper and the condition of the drain. Knowing what affects this can help you avoid a backed-up bowl and a call you did not plan on.
Why Too Much Paper Can Clog a Toilet
Toilet paper is made to break apart in water, but that takes a little time. When a thick bundle enters the narrow, curved passage inside the toilet all at once, it can wedge in place before it softens.
Once paper starts to collect, waste and more paper can build up behind it. A toilet that was flushing fine can suddenly start filling up instead of draining. Sometimes the clog is only partial at first. The bowl may drain slowly for a few days before it stops draining at all.
What Affects How Much a Toilet Can Handle
Several factors can make one toilet more likely to clog than another:
- the toilet’s design and how strongly it flushes
- how much water the tank releases with each flush
- thick or quilted paper, which may take longer to break down
- buildup inside the toilet that narrows the passage
- a partial blockage in the drain line beyond the toilet
If a toilet clogs often even with normal use, the problem may be the toilet or the drain, not just the paper. A plumber can help figure that out. Older toilets and toilets with worn tank parts may also release less water than they should, which can weaken each flush.
Simple Habits That Help
A few habits can lower the chance of a paper clog:
- Flush more than once during a visit if a lot of paper is needed.
- Fold or tear paper instead of wadding it into a ball.
- Keep wipes, paper towels and tissues out of the toilet.
- Teach children how much paper to use and when to flush.
NYC DEP asks residents to flush only human waste and toilet paper. Everything else, including wipes labeled flushable, belongs in the trash.
If the Toilet Starts to Clog
If the water rises after a flush, do not flush again. That can cause the bowl to overflow. Keep children and pets away from any spilled water and avoid touching it. Wash with soap and water after any contact.
In Bronx apartment buildings, report repeated clogs to the super, since a shared line may also be involved. Note how often the toilet clogs and what was flushed, which can help with finding the cause.
