What snaking is, and what it does not do
Snaking, also called augering, uses a long, flexible cable that is fed into a drain and turned so that its end can break through a blockage or hook onto it and pull it back out. In general terms, a smaller cable is used for a fixture drain and a longer cable for a drain further from the fixture. Snaking is a mechanical method: it works on the blockage itself, not on the whole pipe. That is also its limit. A cable that punches a hole through a blockage leaves buildup on the pipe wall behind it, so it does not remove a grease coating, mineral scale, or a full mass of roots from the pipe wall. Those limits matter when a drain keeps clogging after snaking, because the wall buildup that snaking leaves behind may be the reason it returns.
