Toilet paper can clump and cause a blockage in the toilet. If the water in the toilet is draining slowly or refuses to drain at all when you flush, there may be a clog of toilet paper that needs to be dislodged.
To dislodge toilet paper, use a plunger or a plumber's snake. A plunger create suction to dislodge the toilet paper and allow it to get flushed, and a plumber's snake is threaded down the pipe and used to shred the clog or bring it back up.
If the clog is primarily toilet paper, it should be simple to break up with hot water and dish soap. Bail out the toilet until there is only a little bit of water in it, and then pour in ½ cup of hot water and ½ cup of dish soap. Allow the solution to work for half an hour and then flush the toilet.
According to Consumer Search, the type of toilet paper that you use does not affect the number of toilet clogs that you experience. While thinner, one-ply toilet paper may flush more readily, there is the temptation to use more of it.
