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.
My bathroom sink drains slowly but the stopper is clean. What else could it be?
If you have pulled the stopper and cleaned off the hair and soap film and the sink still drains slowly, the restriction is further down. The stopper mechanism is only the first few inches. Most of the slowdown lives in the pivot rod area, the tailpiece, the trap, or the pipe beyond it.
The common cause is a layer of soap scum, toothpaste and hair that binds together on the pipe wall. It narrows the pipe a little each month, and the sink slows long before it stops.
Safe checks you can do: set a bucket under the sink and unscrew the trap. Clear out what you find and rinse it. Look at the short pipe going into the wall for build-up you can reach with a bottle brush. Fill the basin and let it run, then watch whether the water drains evenly or with a gurgle. Skip chemical cleaners, which can soften plastic fittings and leave caustic liquid sitting in the trap.
Gurgling is a clue. A sink that drains slowly and gurgles can point to a blocked vent, because the drain cannot pull air behind the water. If the toilet or shower near that sink also acts up, the blockage may be in the shared branch line or the main drain, not the sink itself.
One slow sink with everything else normal usually means a local clog, and a cable machine through the trap arm is enough. If the pipe clears and slows again within a few weeks, a camera inspection can show whether the pipe wall is scaled over or has a sag that holds water. Heavy scale or soap buildup in the branch line may call for hydro jetting.
Call and stop using the sink if you see water leaking from the trap or the wall, if sewage smells from the drain, or if several drains in the house slow at once. That pattern usually means the main line is partly blocked.
Cost depends on how easy the pipe is to reach, whether the cleanout is nearby, how far the plumber must run the cable, and whether any worn pipe has to be replaced.

We had roots cut out of our sewer line a year ago and now it is backing up again. What actually stops them coming back?
Cutting does not stop roots. It clears the pipe so water can pass, but the roots are still alive outside it and they grow back through the same opening. A year is a fairly typical time for a line to fill up again, and sometimes it is faster.
Roots get in where the pipe is not sealed: a joint that has shifted, a hairline crack, a broken section. Tree roots follow moisture, and a sewer pipe leaks a little water and vapor, which draws them in. As long as the entry point is open, regrowth is only a matter of time.
What actually removes the cause is closing that opening. There are three common routes, and the right one depends on what a camera inspection shows.
A spot repair fixes a single bad joint or short cracked section. It makes sense when the rest of the pipe is sound.
A liner is a resin-saturated sleeve that is cured inside the old pipe, sealing joints and cracks along its length. It suits pipes that are cracked or leaking at several joints but are still round and in place.
Replacement is the answer when the pipe is collapsed, badly offset, bellied or made of a material that has failed, such as clay in poor shape.
Chemical products poured into the line, or foaming treatments, may slow some regrowth but do not seal the entry point, so they are not a repair.
Safe checks you can do:
Note when the slow drains started and which fixtures are affected. Mention the earlier root cutting to the plumber, and the approximate date.
Stop running water and call now if sewage is backing up into the house.
If a full repair is not possible right away, scheduled cleaning before the next backup can manage the problem, though it stays a stopgap. Cost depends on how many entry points there are, depth and length, access around trees and hardscape, the method chosen and permits under local code.

We are buying a house. Is a sewer camera inspection before closing worth it, and what does it find in older homes?
A standard home inspection covers what can be seen and reached. It does not follow the main drain out under the yard, and that buried pipe is where the expensive surprises sit. On an older house, a camera inspection of the sewer line before closing is usually worth doing.
A plumber feeds a small waterproof camera down the line, normally through a cleanout, and watches the pipe on a screen. The run goes from the house toward the street connection, and the plumber notes how far along each problem sits.
Here is what tends to turn up in older homes:
Tree roots in clay or concrete pipe, entering at joints. They look like fine hair or a thick mat.
Cast iron that has scaled up inside, narrowing the bore, or has cracked along the bottom.
Fiber pipe made of tar and wood pulp, which can go oval and collapse over time.
A bellied section, where the pipe has sagged and holds a pool of water.
Offset or separated joints where the soil has moved, and old broken sections from past digging.
Ask for the video or screenshots, and for the distance of each defect from the cleanout. That gives you something concrete to show your agent and the seller. A root problem that a cable machine or hydro jetting can clear is a very different matter from a collapsed section that needs digging or a trenchless liner. What a repair costs depends on depth, access, how much yard, driveway or slab has to be opened, the materials, and local permit rules. Those are the things to ask a plumber about once the footage is in hand.
Two practical points. First, find out whether the cleanout is reachable, and tell the seller you need access during your inspection window. Second, a camera cannot see through a line that is full of water or packed solid, so the plumber may need to clear it first. If the seller says the line has never given trouble, that is useful, but it does not show the condition of the pipe.
Ask also whether the lateral is shared with a neighbor, since that changes who deals with a defect.

Do enzyme or bacterial drain treatments actually work?
Your drain is slow and the bottle on the shelf says it eats clogs. Does it work? A little, in the right situation, and no for most clogs people buy it for.
Enzyme and bacterial products break down organic film: grease, soap residue, food particles and the slimy layer that builds on the inside of a pipe. They work slowly, over days and repeated doses. Used that way, they help keep a clean line clean.
What they cannot do is just as important. They will not dissolve a hairball in a tub trap, a wad of wipes, a child's toy or a solid plug. They do nothing to tree roots growing into a clay joint. They cannot lift a bellied line that holds water, flatten a collapsed section, or seal a cracked pipe. Scale inside old cast iron is mineral, not organic, so it does not respond either.
If one fixture is slow, the cause is usually local: hair, soap scum or grease in that trap or branch. If every drain in the house is slow, or water backs up in the lowest fixture when you run the washer, the problem is in the main line, and a bottle from the shelf will not reach it.
Safe homeowner check: remove the stopper or strainer and clear what you can by hand. Try a plain plunger. Flush with hot tap water, not boiling, which can soften or damage some pipe and fittings. If you use an enzyme product, follow the label, usually at night when the drain sits unused. Do not mix it with chemical openers.
Stop running water and call now if sewage or gray water comes up in a tub, shower or floor drain, if the toilet and the sink back up together, if gurgling comes from several fixtures.
A cable machine is enough for a single soft clog or a simple plug in one branch. If the line keeps slowing down, a plumber may suggest hydro jetting to clean the full pipe wall, or a camera inspection to see roots, a belly or a damaged joint before anything else is done.

Ask the plumber what they found on the pipe wall, not just whether the water now runs. If it was grease or film, ask whether a maintenance routine makes sense for your line. If it was roots, a belly or damage, ask what repair is involved. The scope depends on access to the pipe, the materials needed, how much has to be opened up, and any permit or code requirement.
