You Snaked It and It's Still Clogged. Reaching a Clog and Clearing One Are Different Events.
A hardware-store auger runs out of cable, stiffness and torque long before it runs out of pipe. Here is where it actually stops, and what a cable cannot fix at any length.
There are two reasons a drain is still blocked after you snaked it. Either the cable never got there, or it got there and bored a passage through the blockage without removing it. The second is the confusing case, because the drain runs afterwards and reads as a win. Both are ordinary outcomes of using a household auger on a problem that was never a household-auger problem, and both are diagnosable from your kitchen floor.
Here is where a cable stops, and what it cannot fix at any length.
Where a hardware-store auger runs out
Length is the limit people assume, and the least important of the three.
Diameter is the real one. A cable thin enough to turn the tight bend of a sink trap is far too thin to stay straight inside a three- or four-inch drain line. Given that much room it does not drive forward — it helixes, coiling against the pipe wall in a long spring, absorbing the push you are giving it. You feel resistance and assume you have found something. You have found the cable buckling.
Torque is the second. The head only works if the twist you put in at the handle arrives at the far end, and every bend the cable passes takes a share of it as friction. After a trap, a wye and a couple of changes in direction, much of what you are turning is spent turning cable against pipe rather than a head against a blockage.
And it follows the path of least resistance, not the path you intend. A cable fed into a fixture drain has several ways to go and no preference. It coils inside the trap. It turns up into the vent, which is clean, straight and empty and therefore inviting. It takes the first branch it meets. What you feel at the handle in all three cases is identical to heading down the line.
Did it reach the clog, or did it just stop?
This is answerable in about a minute and it is the single most useful thing you can do before calling anybody.
Mark the cable and measure what went in
Tape the cable where it enters the fixture before you start, and again where it sits when the cable stops. The distance between the marks is how far you actually got. Compare it against the real distance to the cleanout or to the wall the line leaves through. Eight feet paid out on a thirty-foot run means you found a fitting, not a blockage.Look at what came back
Pull the cable out slowly onto a towel and look at the head. Grease, hair, root fibre, paper, black sludge — each tells you something. A head that comes back clean did not engage anything. That is not a clear line; that is a cable that went somewhere else.Run real volume, not a trickle
A bored passage passes a thin stream happily. Fill the sink or the tub and let it all go at once. A line that handles a trickle and backs up under volume has an opening rather than a clear bore.Watch a second fixture while you do it
If anything else gurgles, rises or slows while that volume drains, the restriction is downstream in shared pipe and the fixture you have been working on was never the problem.
Reaching it is not clearing it
A cutting head makes a hole. That is its whole design intent and it is the right intent for the right problem.
Fed into something discrete — a mass of wipes, roots that found a single joint, an object — a cable engages it, cuts it, and either removes it or pushes it through. That is a genuine clearing and it lasts.
Fed into a line closing gradually with grease and soft build-up along its whole length, the same cable bores an opening roughly the width of the head and leaves the coating exactly where it was. Water flows. The problem has not been solved, it has been reset, and the remaining material starts closing that opening from the moment you pack the tool away. Which of the two you have is the entire question, and it is set out in hydro jetting versus snaking.
What a cable cannot fix, at any length
Neither a hand auger nor a professional drum machine repairs pipe. If the line has a defect, cleaning it produces a real improvement that lasts exactly as long as it takes the defect to refill it.
A belly — a section sagged below the line of fall — holds standing water permanently. A cable passes straight through and changes nothing about the sag. Solids settle in the low spot again as soon as normal use resumes.
A break or a crack lets soil in. You can push soil aside with a cable, which is why a break often responds at first. The soil comes back, because the ground is still there and so is the hole.
Roots at a joint get sheared by the head, not removed at the source. They entered through a defect and they re-enter through the same defect at their own pace. A cable buys a season.
An offset or dropped joint leaves a lip inside the pipe that every solid catches on. Running a cable through does not change the height of that lip.
A collapse is where the cable stops hard and will not pass at any pressure. Forcing it there is how a cable gets left in a line.
Two things about this county that change the answer
A lot of addresses here have no gravity main to cable. At the water there is very little fall to work with — the Gulf Shores coordinate reads about 7 feet of ground elevation and Orange Beach about 11, against 271 feet at Bay Minette — so sewage often cannot move by gravity at all. Those properties have a grinder pump in the yard and a small-diameter pressure line leaving it. A cable has no business in a pressure line, and on a property like that a whole-house backup is at least as likely to be the pump or its float as anything you could reach with a tool. If several fixtures are unhappy at once around Gulf Shores, the pump belongs at the top of the list.
The bedding under a lot of these lines is sand. Sandy soil carries a pipe well until water moves through it, and then it moves too. That is the mechanism behind most of the bellies found on camera here, and why a line that ran fine for twenty years can develop a low spot with nothing done wrong.
The honest next step is a camera, not a bigger snake
After a failed clearing two possibilities remain, and they want opposite things spent on them. Either the line is dirty along its length, which wants scouring rather than boring, or it is defective, which will defeat any cleaning method on any schedule.
A camera run from the cleanout separates those in a few minutes. It gives you the material, the condition, the distance to the fault and — with a locator — a mark on the ground. That is the difference between a quoted repair and a guessed one. What the clearing side costs is published so you can read it beforehand, and drain cleaning locally starts with looking for exactly this reason.
A defect is sewer line repair rather than another cleaning, and the money stops going into the same hole. If the same drain has now blocked more than twice, the interval itself tells you which of the two you have — the subject of why the same drain keeps clogging.
And if two or more fixtures are backing up together right now, stop running water. That is a main line problem and every gallon you add ends up on a floor. A single slow drain can wait until morning; that one cannot.
