Can a drain under a concrete slab be cleared without breaking the floor?
Usually, yes. Clearing a blockage and repairing a broken pipe are two different jobs, and only the second one needs the floor opened.
In a slab-on-grade house the drain lines run inside or beneath the concrete. There is no crawlspace to inspect, so symptoms are the only evidence you have. A cable or a hydro jetter still reaches the line through a cleanout or through a pulled toilet. Grease build-up on the pipe wall, roots in a joint and scale in cast iron can all be cleared that way.
What does need the floor opened is a cracked, collapsed or bellied section under the slab. A bellied line holds water and collects waste however often it is cleared. In older housing stock where clay or cast iron was the standard, failed sections are more likely.
A camera inspection with a locator pinpoints the fault. The plumber finds the exact spot and marks it on the floor before anything is cut, which keeps the opening small. What the job involves is driven by access, the materials, how much concrete must be opened and removed, and any permit or code requirement. Opening a slab often brings one in.
Safe homeowner check: note whether one fixture is slow or every drain is affected. A single slow fixture is usually a cable job on a branch line. Every drain backing up points to the main line or the sewer lateral.
Stop running water and call now if the whole house is backing up. Report water staining or a warm, damp patch on the floor, because it can mean a leak under the slab.

A spot repair under a slab is more disruption than most people picture. The plumber breaks out a section of concrete, digs down to the pipe, replaces the damaged length, and the floor is patched. Dust, noise and a few days without some fixtures are normal. Furniture and flooring over the area must be moved first, and tile or a finished floor may not match after patching.
For longer runs of damage, some plumbers can line the pipe from inside, or route a new line overhead or outside the house, which avoids cutting the slab. Whether either suits your pipe depends on its condition and on local code.
Ask to see the camera footage and the locator mark on the floor before any cutting begins. Mention in-floor heating, radiant tubing or a post-tension slab if you have one. Cutting into those without knowing is dangerous, so the plumber needs to hear about them before a saw comes out.
There is a soggy strip, a sinkhole or an unusually green line of grass over where my sewer runs. Is that a broken sewer line?
It can be. A wet strip, a dip in the lawn or a stripe of grass that is greener than the rest, all following the path of the sewer, is a classic sign that the pipe is leaking into the soil. Waste water carries nutrients, so the grass above it grows lush while the ground underneath stays soggy.
A sinkhole is more serious. If soil is washing into a cracked or separated pipe, it leaves a void that grows over time. The surface may look fine until the roof of that void gives way. Keep people, pets and vehicles off the area and do not fill it yourself with a quick load of dirt, because the hole will usually return.
Other things can look similar, so check before assuming. A leaking irrigation line, a broken water supply pipe or a downspout discharging at that spot can all soak a strip of lawn. A simple test: shut off every tap and appliance, then look at your water meter. If it keeps moving, the leak is likely on the supply side, not the sewer. If the meter is still, and you also notice slow drains, gurgling, a sewage smell outdoors or backups, the sewer is the stronger suspect.
Safe checks you can do:
Note where the wet or green strip runs and whether it lines up with the cleanout or the path to the street. Reduce water use until the line is looked at.
Stop running water and call now if sewage is surfacing, a hole is opening, or drains inside the house are backing up.
Cleaning alone does not fix a broken pipe. A camera inspection is how a plumber finds the break, shows how far the damage runs and tells whether the pipe is cracked, offset at a joint or collapsed. Repair can then be a spot repair, a liner through the existing pipe, or replacement of a section. Cost is driven by depth, length of pipe affected, what sits on top of it such as a driveway, trees or a patio, how much has to be excavated, the pipe material and permits under local code.

My house is old and the sewer might be Orangeburg pipe. What does that mean for cleaning?
Orangeburg is a pipe made from wood pulp fibers pressed together and sealed with pitch, also called bituminous fiber. It was used for house sewer lines in the middle of the last century, and some homes still have it between the building and the street. It was never as strong as clay, cast iron or modern plastic.
Over time the pipe softens and loses its shape. It can turn oval, sag, flake at the inside wall or collapse. Joints are easy targets for roots. So an old house with repeated backups and a history of roots or low spots may be sitting on this kind of line, though only a camera can confirm the pipe material.
That matters for cleaning, because the usual tools are rougher on Orangeburg than on other pipe. A heavy cutting head on a cable can tear at a soft wall. High pressure from a jetting nozzle can strip layers off or push through a weak spot. A plumber who knows or suspects the material will start with a camera inspection, use gentler tools, and avoid forcing a machine through a section that has already deformed.
Tell the plumber on the phone how old the house is, any earlier line repairs, and whether the line has been cleaned before. If you can, mention what you have seen: slow drains, a repeat clog, wet soil over the line.
Safe checks you can do:
Ask whether any earlier paperwork notes the pipe type. Limit water use if backups are frequent.
Stop running water and call now if sewage is coming into the house or the yard.
Cleaning may buy time on a line in fair shape, but it does not strengthen the pipe. If the camera shows a collapsed or badly ovaled section, the realistic options are lining where the shape allows it, or replacing the line. Cost depends on pipe length and depth, access, what has to be dug or removed, the repair method and permits under local code.

What actually happens when a plumber comes to clear my drain, from the moment he arrives to the last flush?
Most people only see the machine come out of the truck. There is more to the visit than that, and knowing the order helps you tell a careful job from a rushed one.
An independent plumber usually starts with questions. Which fixtures are slow, which are fine, when it started, and whether you have noticed gurgling or a smell. One slow sink points to a branch line. Every drain in the house acting up points to the main line.
Next comes a look at access. That might be a sink trap, a tub drain, a toilet that has to be pulled, or a cleanout outside or in the basement. Floors and cabinets get covered with towels or a drop cloth.
Then the plumber picks the tool. A hand auger or small drum machine suits a sink or shower. A larger cable machine suits a main line. If grease or heavy scale is suspected, hydro jetting may come up instead, and a camera may be suggested before anything else.
The cable goes in and is fed forward by feel. A clog gives resistance, then a change when the cutting head breaks through. Roots, grease and soft paper each feel different, and a careful plumber will tell you what the cable seemed to hit. When the cable comes back out, whatever clings to it is worth a look. Hair, wipe fibers, root hairs or a greasy paste all point to a cause.
After that comes the test flush. Water runs through the fixture, and often through several fixtures at once, while the plumber watches for slow movement, gurgling, or water rising in a neighboring drain. At a cleanout, the plumber watches the flow pass. This step matters most. A line that drains well for ten seconds and then slows is only partly open.
Last, the plumber explains what was found. If the blockage was in the main line, has come back before, or the cable stopped at the same spot each time, a camera inspection is the sensible next step, because a cleared pipe and a healthy pipe are not the same thing.
Cost depends on access, how far the cable has to travel, whether a toilet has to be pulled, and whether extra equipment is needed.

Can I watch the camera footage from my sewer line, and what should I ask the plumber to show me?
Yes, you can ask, and a plumber who does this work properly will usually be glad to show you. The picture is the clearest evidence there is of what is happening inside a pipe you cannot see.
Most inspection cameras feed a small monitor at the cleanout or a tablet held by the plumber. Ask to watch it live. Ask to see the footage again afterward, and whether it was recorded. A recording matters if you later need a second opinion, a repair quote from another plumber, or a record for a home sale.
Here is what to ask to see.
The start of the run. A clean, round pipe wall tells you the line was open and what material it is, such as clay, cast iron or plastic.
Any joint that looks offset, cracked or separated. Ask the plumber to pause on it.
Root growth. Fine roots look like hair or threads at a joint. Heavy roots fill the pipe like rope.
Standing water. A section that holds water is a bellied line, a low spot where debris collects. Ask how long the section is.
Scale or heavy buildup, especially in cast iron, where the wall looks rough and lumpy.
The end of the run. Where did the camera stop, and why? A collapse, a hard blockage, or a break all look different.
Then ask how far from the cleanout each problem sits. Many cameras carry a footage counter or a locator that finds the spot from above. That distance is what tells you how much digging a repair might involve.
A few cautions are worth knowing. The image can look worse on a small screen than it is, and a single hairline crack is not the same as a collapse. A plumber should be able to say which it is and what it means for the next step. If the camera could not pass a blockage, ask what is beyond it, because the camera has only seen part of the line.
What camera work adds to a visit depends on access and how long the run is, and it often heads off a repair based on a guess.
