Plumbing estimates are rarely one-size-fits-all. Several variables can push your total toward the higher end of the spectrum: How Much Does a Plumber Charge to Snake?
If you are looking at an engineering or topology paper on this subject, it is interesting because a toilet snake is a "passive" mechanism. It has no brain or sensors, yet it must "make decisions" (mechanically) to navigate tight corners. The paper likely analyzes how the stiffness of the cable and the geometry of the toilet trap interact to allow the cable to bypass the curve without getting stuck. how much does a plumber charge to snake a toilet
You mentioned an "interesting paper." In the world of Economics and Mathematics, there is a famous paper that uses plumbing—specifically —as a central metaphor to explain complex concepts. Plumbing estimates are rarely one-size-fits-all
You might be thinking of research regarding "The Mechanics of a Plunger" or "Fluid Dynamics in Toilet Snaking." It has no brain or sensors, yet it
