Are you dealing with a right now, or are you just curious about the science of plumbing ?

Great question — the short answer is .

Furthermore, the "dissolution solution" relies heavily on the nature of the clog itself. If the blockage consists solely of a wad of toilet paper, patience may indeed be a viable cure. The paper will absorb water, soften, and eventually release its grip on the pipe. But this scenario assumes a relatively new, wide-diameter plumbing system. In older homes with cast-iron pipes, or in systems with pre-existing buildup of mineral scale or grease, toilet paper acts less like a temporary obstruction and more like a dam. It catches on rough surfaces, accumulating other debris, and hardening into a stubborn mass. In these instances, the paper is not merely resting in the water; it is binding with the pipe itself, and waiting will only make the problem more difficult to resolve.
