You're not the first to wonder why your toilet paper refuses to go down the drain. There are two main reasons why this could occur. Firstly, there may be a clog hindering suction. This clog may occur as a result of using excess toilet paper. If this is the problem, a plunger can fix it. However, if the plunger doesn't work, the fault may be from the toilet paper. You should search it up to see if it is biodegradable and septic safe. If the toilet roll isn't septic safe, it will be hard to dissolve and flush away. If you have questions regarding any toilet paper in this compilation that doesn't leave residue, please visit the brand's website or contact customer care.
