Should the job use a cable machine or hydro jetting?
It depends on what is in the pipe and how far it reaches. A cable machine, sometimes called a snake, is usually enough for a localized clog from hair, paper, or a small root intrusion. The rotating cable punches a channel through the blockage and restores flow, and for a single slow bathroom sink or tub that is all the job needs. The limit of a cable is what it leaves behind. It opens a hole through the middle of a clog, but grease, scale, and sludge stay stuck to the pipe wall, so the line narrows again within weeks. Hydro jetting sends high-pressure water through the line and scours the full interior wall. It is the better call for grease coating a kitchen line, recurring clogs in the same spot, roots that were cut back once and returned, or a line that keeps slowing down after cabling. A jetter needs a reachable cleanout, and it is not right for a pipe that is cracked or collapsing. That is where a camera comes in. A camera inspection shows the pipe's condition before the plumber chooses a method. The plumber decides after seeing the line, and that choice affects the cost of the visit for a home in Hilliard, OH.
One practical point is that the choice is not always made in advance. A plumber often starts with a cable, finds out what is actually in the line, and then moves to a jetter if the cable returns with grease or sludge instead of a clean break. For that reason it helps to ask which method is planned and what would make the plumber change course. Jetting also depends on pipe condition, which is another reason a camera sometimes comes first on an older line. Clay and cast iron that are thin, cracked, or shifted can be damaged by high pressure, while newer plastic pipe handles it well. Water use matters too: a jetter sends a lot of water into the line, so the drain has to be open and flowing downstream. After either method, run water for several minutes and watch for slow spots or gurgling that might mean something is still in the way.
Can a blocked vent stack cause slow drains even when there is no clog?
Yes. If a sink gurgles, a toilet burbles when another fixture drains, or water moves slowly with no clog anywhere, a blocked vent stack is a likely cause. The vent is the pipe that runs up through the roof. It lets air in behind the water so drains flow freely. When it is blocked, the drain pulls against a vacuum, and the water crawls out of the fixture.
Common causes are leaves, a nest or debris at the roof opening. Inside the wall, a vent can also collapse or fill with scale.
A vent problem often shows up on several fixtures at once. They drain, just slowly, and they gurgle. A clog usually stops one fixture. If every drain in the house is backing up, that is a main line job, not a vent.
Safe homeowner check: listen for gurgling, look at the roof opening from the ground, and run each fixture one at a time to see which ones act up. Do not climb onto the roof yourself.
Stop running water and call now if sewer odor is strong indoors, or a toilet or floor drain is bubbling up.
A cable machine run down from the roof opening clears most vent blockages. If it keeps coming back, a camera inspection shows whether the pipe is damaged. Cost depends on roof access and how far the blockage sits.

Several things can make a vent problem worse or confuse the diagnosis. In cold climates, frost can close the roof opening as moisture freezes around the rim, so symptoms appear in winter and ease in spring. A common mistake is treating the gurgle with repeated plunging or drain chemicals, which does not touch the real cause and can leave caustic liquid in the trap. Another sign it is getting worse is a toilet that fills slowly after flushing or a trap that loses its water seal, because that lets sewer gas into the room. Older homes often have vents routed through cramped walls with long horizontal runs where debris collects, while newer homes may use air admittance valves under sinks that can wear out and stick. When you call, mention which fixtures gurgle and in what order, since that tells the plumber which branch to follow first.
What is a bellied or sagging sewer line, and can it be cleaned?
A belly is a low spot in the sewer line where the pipe has sunk. Water and waste stop and sit in the dip instead of flowing on. Solids settle there, grease coats the pipe wall and paper catches. You see it as drains that run slow, a toilet that needs repeated flushing, or a line that clogs again a few weeks after it was cleared.
The cause is usually a pipe that lost support underneath it, or a joint that shifted.
Can it be cleaned? Yes, up to a point. A cable machine can open a blockage sitting in the belly, and hydro jetting can wash grease and buildup off the pipe wall. Neither fixes the dip. The belly keeps holding water, so the buildup returns.
A camera inspection tells you the rest. It shows how deep the belly is, whether the pipe is cracked, and whether roots have entered a joint. Cost depends on how deep the line is, how much has to be dug up or removed, the materials involved and any permit.
Safe homeowner check: note whether one fixture or the whole house is slow. One fixture points to its own branch. Every drain slow points to the main line.

Left alone, a belly tends to get worse in a predictable way. The standing water softens the soil around the pipe further, the dip deepens, and the clogs come back faster each time. Another warning sign is a faint sewage smell in the yard or a patch of lawn that sinks or stays wet, which can mean the pipe has separated at a joint. Older homes with clay or cast iron lines are the most likely to have a belly, because those pipes sit in sections and shift as soil settles. Newer plastic lines can also sag when the trench bedding was uneven. When you speak to the plumber, ask what the camera shows about the depth of the dip and the condition of the pipe at that spot. If the pipe is intact, a spot repair may be possible. If it is cracked, replacing that section is the lasting fix.
Why did the clog come back worse after I used a store-bought drain snake?
You ran a snake from the hardware store, the water moved for a day, and now the sink is worse than before. That is common, and it comes down to the tool.
A thin hand-crank snake often punches a small hole through the middle of a clog. Water trickles through, so it seems fixed. The clog is still there, and it gets packed tighter as new debris catches on it. Sometimes the snake pushes the clog deeper into a bend, where it is harder to reach. A snake also does not scrape the pipe wall, so the grease build-up stays and the clog forms again quickly.
It is the wrong tool for roots, a bellied line holding water, or scale in cast iron. Those need a heavier cable with a cutting head, hydro jetting, or a camera inspection to see what is actually in the pipe.
Safe homeowner check: place a bucket under the trap, remove it and clear it by hand. Do not add chemical cleaners after snaking, because the plumber may then be working in caustic water.
Stop running water and call if the snake stuck or will not come back out, if other drains gurgle or back up, or if you smell sewage. That points past a single fixture to the main line.

After a failed snake attempt, leave the fixture alone and tell the plumber exactly what you did: the type of snake, how far it went in, whether it hung up, and whether you used any chemical cleaner first. That saves time on site and tells them whether the cable is still stuck or the clog was pushed into a bend. Do not keep running the snake in the hope that it will break through. Forcing a thin cable through a trap or a sharp bend can scratch the pipe wall or damage the trap, and in old cast iron it can knock loose scale that adds to the blockage. Also stop using the sink for a few hours if you can, because the extra water tends to carry loose debris deeper. Expect the proper clearing to include a look at the pipe wall afterwards, so you know whether this was a one-off blockage or a pipe that keeps catching debris.
Can I rent a hydro jetter or a big drain machine and do the main line myself?
"Can I just rent a hydro jetter and do the main line myself?" You can rent one at many tool shops, so it is a fair question. The honest answer is that it is a bad bet on a main line, for reasons of both pipe and safety.
A hydro jetter pushes water at very high pressure through a hose with a nozzle that pulls itself down the pipe. In the right hands, on sound pipe, it cleans grease and scale off the pipe wall. In the wrong hands it can break old clay or cast iron, wash out joints, drive water into a cracked pipe, or punch through a thin spot. Root intrusion at a clay joint can hold the nozzle, and a bellied line can trap it.
A large drain machine has its own risk. The spinning cable can whip, snag and twist. It can wrap a hand or arm in a second.
There is a bigger issue. Without a camera, you do not know what you are cutting. A main line that backs up may be roots, a bellied line, a collapsed section or a failed sewer lateral. Clearing the blockage may only open a hole through it, and it returns soon after.
Safe homeowner check: Run one fixture at a time and note which drains slowly. Check if it is one fixture or every drain in the house. Do not pour drain chemicals into a line that is backing up.
Stop running water and call now if sewage is coming up in a tub, shower or floor drain, the toilet bubbles or rises when you run other fixtures, or you smell sewage in the house. Stop using water in the house until the line is cleared.
A cable machine is enough for a simple clog in a branch line. Hydro jetting is for grease and scale on the pipe wall. A camera inspection is the step that tells the plumber what is in the pipe and what tool is safe to use, which is what a rental cannot give you.
