Can a drain cable or hydro jetting damage old pipes like cast iron, clay or thin-wall pipe?
Yes, it can, and a good plumber knows that before the machine is switched on. Old pipe is not equally fragile everywhere, and the choice of tool depends on what the pipe is made of and what shape it is in.
Cable machines spin a cutting head against the pipe wall. In sound pipe that is fine. In clay with offset joints, the head can catch on a lip and snag. In cast iron with heavy scale, a cutting head can knock loose flakes, and in a pipe already thinned by corrosion it can punch through. Thin-wall plastic or older Orangeburg-type fiber pipe can be gouged or deformed.
Hydro jetting pushes water at high pressure through a nozzle. On solid pipe it cleans the walls better than a cable. On a cracked clay pipe, a corroded cast iron stack, or a joint that has already shifted, that pressure can widen the damage or send water out into the soil.
So how does the plumber decide? Usually from several clues:
The age and material of the house and the pipe, which tells the plumber what to expect.
Past history, such as repeated roots, earlier repairs, or a line that has never been inspected.
How the cable behaves. A head that bounces, stops at the same distance, or comes back with pipe chips or rust flakes suggests the pipe itself is damaged.
A camera look first. This is the most direct answer. If the line is fragile or offset, the plumber can choose a gentler head, lower pressure, or no jetting at all.
If you suspect old pipe, say so on the phone. Tell the plumber the age of the house and the pipe material if you know it. Ask whether the tool will be matched to the pipe, and whether a camera look comes first.
Sometimes the honest answer is that a quick clearing is worth the risk to get water moving, with a plan to inspect afterward. Sometimes it is not. Either way, the decision should be explained to you before the work starts, not after.

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.

My child flushed a toy, or something solid went down the toilet. What should I do, and what should I not do?
Stop first. Do not flush again, even if the water looks like it is going down. Each flush pushes the object further along, and it can lodge in the toilet's trap or in the drain behind it. Tell everyone in the house not to use that toilet.
If the toilet still drains but the bowl is high, leave it. If it is rising toward the rim, lift the tank lid and push the flapper down, or turn the shutoff valve behind the toilet clockwise to stop more water entering.
What is safe to try: if you can see the object near the bowl opening and it is not breakable, put on gloves and pick it up. Use a wet vac or a closet auger only if you are comfortable with it, because an auger can also shove a hard toy deeper. Be gentle with a plunger. A plunger can free a soft item, such as paper or cloth, but it often wedges a solid piece tighter.
What not to do: do not use chemical drain cleaners, which do nothing to a solid object and make the water dangerous to handle. Do not keep plunging hard, and do not push a coat hanger down the drain, which can scratch the porcelain or drive the object into the pipe wall.
If the object has already gone and the toilet seems normal, watch for slow drains, gurgling or other fixtures backing up over the next few days. A small toy can catch in a bend and collect paper behind it. If the toilet becomes slow, or the same one keeps clogging, the object is probably still in the line.
In that case the plumber may pull the toilet off its seat to retrieve it from underneath, which is often cleaner than cabling into a pipe. If the item is in the drain behind the toilet, a camera can find it and the plumber can retrieve it or push it clear. Cost depends on where it lodged, whether the toilet must be removed, and how much access is needed.

The plumber suggested a smoke test. What does that find that a camera does not?
Your plumber says "let's do a smoke test," and you wonder why, when a camera already looked in the pipe. The two tools answer different questions, and the smoke test finds things the camera cannot.
A drain camera travels down the inside of a line. It shows roots, grease, scale, a belly holding water, an offset joint or a crack in the section it can reach. But it can only go where the cable can push it. It cannot climb a vent stack in a wall, it tells you little about the vent side of the system.
A smoke test pushes non-toxic smoke through the drain and vent system under light pressure. Wherever the system is not sealed, the smoke shows itself. It can come out of a cracked vent pipe in the attic, a missing cleanout cap, a broken pipe inside a wall, or a dry trap. That explains symptoms a camera often misses: sewer smell with clean-looking drains, gurgling fixtures, and slow drains caused by a blocked or damaged vent.
One fixture that drains slowly is usually a local clog and rarely needs a smoke test. Sewer odor in several rooms, gurgling at more than one fixture, or a smell that has no clear source points at the system as a whole, and that is where the smoke test earns its place.
Safe homeowner check: pour water into every floor drain and rarely used sink so the traps are full, because a dry trap can mimic a leak.
Stop running water and call now if wastewater backs up in a tub, shower or floor drain, if the toilet will not clear, if you see wet floors or stained ceilings, or if the smell is strong enough to make anyone dizzy or sick. Leave the area and ventilate it first.
A cable machine is enough when the problem is a plain clog. If the smoke test shows a vent or pipe defect, the job becomes a repair, not a cleaning. If the line is coated with grease or scale, hydro jetting may be proposed. If the cause is still unclear, a camera inspection on the drain side often pairs well with the smoke test.

Ask the plumber what they are trying to confirm and where the smoke came out. Ask whether the vent, a wall section or the main line needs repair, and whether a camera pass should follow. The scope depends on access to the pipe, the parts or pipe needed, how much wall, ceiling or floor must be opened, and any permit or code requirement.
The plumber wants to pull the toilet to reach the line. Why would they do that?
You called about a slow drain, and now the plumber says the toilet has to come off the floor. It is actually a common and sensible move, and it is often the cleanest way in.
A cable or jetting hose needs a way into the line. The best entry is a cleanout, a capped pipe fitting on the main drain. Many houses do not have one, or it is buried, painted over or blocked by a wall. Without a cleanout, the toilet is usually the best access point in the house. Pulling it exposes the closet flange and gives the plumber a short, straight shot into the closet bend and then into the main. Going in through a sink or tub means tight turns and a trap, and the tool may never reach the real problem.
It matters most when the blockage is past the branch lines. Roots at a clay joint, a belly holding water, or grease further down the main sit well beyond the bathroom. A straight path lets the cable or jet hose get there with enough control to clear it and, if a camera is used, to see what the pipe looks like.
Think about whether it is one fixture or the whole house. If only the bathroom sink is slow, the plumber should work at that sink. If the toilets gurgle, the tub backs up and a floor drain bubbles, the problem is in the main, and pulling the toilet is a reasonable way to reach it.
Safe homeowner check: look in the basement, crawl space or outside wall for a capped cleanout fitting on the main drain, and tell the plumber where it is. Do not pull the toilet yourself unless you are comfortable with it. The bolts can seize, and the bowl is heavy.
Stop running water and call now if sewage is coming up in a tub or floor drain, if the toilet is overflowing, or if you smell sewer gas.
A cable machine is enough for a simple clog near the closet bend. Roots, a belly or heavy build-up usually call for a camera inspection first, and hydro jetting to clean the pipe wall.

Ask the plumber if a cleanout will be added so the next visit does not need the toilet pulled. Also ask about the new wax ring and any damaged bolts or flange, since the toilet must be reset and sealed afterward. Scope depends on access, parts, the condition of the floor around the flange, and any code requirement for adding a cleanout.
