What Causes a Toilet Overflow?

Several different events can trigger a toilet to overflow, including a clogged drain, a blocked vent, and sewage complications.

A clogged or blocked drain prevents proper flushing, causing the toilet to overflow. In this situation, plunging the toilet may relieve the problem.

Every time you flush, air is pumped and needs replacing from the vent pipe. If the vent pipe is blocked, proper flushing isn’t possible and can eventually result in a toilet overflow. This issue usually requires the help of an experienced plumber.

Finally, two issues related to sewage, a clogged sewer line and a full septic tank, can be the catalyst of a toilet overflow. A clogged sewer line occurs when the sewer line becomes blocked by items ranging from tree roots to sanitary wipes. A full septic tank can be problematic, as excess water will have nowhere to go but back up into your home, potentially resulting in a toilet overflow.
