Two people call your shop on the same Tuesday and open with the same sentence. "I need a camera run down my sewer line."
The first is a buyer whose inspection contingency expires Friday. She has never met the house, she needs a video file and something in writing her agent can forward, and she does not much care what the pipe is made of as long as somebody tells her whether she is about to inherit a problem.
The second has watched the basement floor drain back up three times since March. He has a wet shop vac, a bad feeling, and a rough idea of what a replacement costs from an hour on the internet.
Same request, different jobs, different trucks, different day. If your intake treats both as "sewer camera, book it," one of them gets a technician who shows up without the locator, or without the jetter, or without enough time on the schedule to do the thing the caller actually needed.
Start by separating the deadline from the problem
Ask early whether something is going wrong right now or whether this is due diligence on a purchase. Almost everything downstream branches off that answer.
An active problem call is a diagnostic. The homeowner has symptoms, and the camera is how you find the cause. The line may need clearing before the camera goes anywhere useful, which changes the length of the visit and what the technician needs on the truck.
A real estate call is a deliverable. The buyer wants a recording, a written summary, and usually a locate on anything that looks bad, because the next conversation is a negotiation with a seller. There may be a lockbox, an agent coordinating access, and a date that cannot move. Nobody is authorizing a repair on the spot, and the technician needs to know that before they arrive.
Both are worth taking. They just are not the same appointment.
The symptoms worth pulling out on the phone
When there is an active problem, the pattern of symptoms tells your technician more than the word "backup" ever will. Three things are worth getting on the ticket.
How many times has it happened, and how far apart? A one-off clog after a holiday weekend with twelve people in the house is a different animal from a backup that has returned every couple of months for two years and cleared with a cable each time. Recurrence is the signal. A line that keeps closing back up on a schedule is usually telling you about roots, a belly holding water, or a joint that has shifted, and none of those are fixed by another cable pass. Ask how many times, when the last one was, and who cleared it.
Is one fixture slow or several? This is the single most useful question on the call, and most intake scripts skip it. One slow lavatory is a fixture problem. A toilet that gurgles when the washing machine drains, a tub that fills when the toilet flushes, or the lowest drain in the house backing up when anything upstairs runs, that is a main line pattern. Ask the caller to walk through which fixtures act up and whether they misbehave together.
What is happening in the yard? Homeowners rarely connect the yard to the drains, so ask directly. A soft or sunken patch of ground, a spot that stays soggy in dry weather, a strip of grass greener and faster-growing than the rest of the lawn, a smell near the cleanout, a section of walkway that has dropped. Any of those, sitting along the run between the house and the street, belongs on the ticket before the technician leaves the shop.
Ask what has already been done, too. A previous plumber's cable, a hydro jet, a repair by the previous owner. And ask whether anyone has ever said "root intrusion" or "collapsed" to them before, because if someone has, the caller often has a report or a video sitting in a forgotten email.
Home age tells you what is probably in the ground
You cannot identify pipe material over the phone, and you should not try. What you can do is ask when the house was built, whether the sewer has ever been replaced, and whether the caller knows of any work done in the front yard. That gives your technician a working guess to confirm on camera.
As a rough guide, and only as a guide: older homes commonly have vitrified clay in the ground, which comes in short sections with joints that roots find. Some mid-century construction used a bituminous fiber pipe often called Orangeburg, which tends to deform out of round as it ages. Cast iron shows up on plenty of houses, and its failure mode is scale on the walls and the bottom channeling out. Newer work is generally plastic. Plenty of houses are a mix, because somebody replaced the first twenty feet and stopped at the property line.
Say all of that as a possibility, never as a finding. The camera is what settles it. A caller who hears "houses your age often have clay, and clay joints are where roots get in, so that is one of the things we will be looking for" understands what they are buying. A caller who hears "you have clay, it is probably collapsed" has been sold something nobody has looked at.
Cleanout access decides how the visit goes
This is the question that most often turns a booked job into a wasted trip, and it is entirely answerable on the phone.
Ask whether there is a cleanout, and if so where. Outside near the foundation, in the yard closer to the street, in the basement or crawlspace, in a garage floor, or in a utility closet. Ask whether the caller can see the cap and whether anything is sitting on top of it, since cleanouts spend their lives under decks, mulch beds, storage shelves, and the occasional patio poured over the whole thing.
If the caller does not know of one, that is not a dead end, it is information. The technician may need to pull a toilet or find another access point, and that is a longer visit with a different setup. Better to plan for it than to discover it in the driveway.
While you are there, take the practical details. Slab, crawlspace, or basement. City sewer or septic, because a septic call is a different conversation and some shops do not take them. A working outside spigot if the job may involve jetting. Where a truck can park and how far that is from the access point. Dogs, a locked gate, a code for the driveway.

The line has to be clean enough to see
Worth setting the expectation on the call: a camera in a line full of standing water, sludge, or paper does not produce a useful video. If the line is actively backed up, it usually has to be cleared before anyone can see the pipe wall, which means the visit may be a cleaning and an inspection rather than an inspection alone.
Tell callers that before they book. The homeowner who was quoted an inspection price and gets handed a bill with a cleaning on it feels like the price changed. The one who was told on the phone that a blocked line normally has to be opened first understands why the second line item exists. This is also why the "is it backed up right now" question belongs early in your script rather than buried at the end.
What the video shows, and what it does not
Callers arrive thinking the camera answers every question about the pipe. Setting that boundary on the phone makes the on-site conversation much easier.
What a camera inspection can generally show: the condition of the pipe wall along the reachable run, roots coming through joints, cracks and offsets, a section holding water where the grade has sagged, scale and buildup, and where the pipe changes material. Paired with a locator and a sonde, the technician can usually mark where the line runs across the yard and give an approximate depth, which is what a repair estimate depends on.
What it does not do, and callers should hear this before the truck arrives:
- It stops where it stops. A hard blockage, a collapse, or a tight fitting can end the run, and the pipe past that point is unknown until the obstruction is dealt with.
- It sees the inside surface, not the pipe wall thickness or the soil around it. A pipe can look acceptable on video and still be near the end of its life.
- It is a snapshot. A line that scoped clear in March can be backing up in September, especially where roots are involved.
- It does not settle who owns what. Where responsibility shifts from the homeowner to the municipality varies by locality, and that is a question for the local utility rather than a claim to make on the call.
- It is not a leak test on the joints. The camera shows what the lens can see, and a joint can pass water into the soil without looking dramatic on video.
None of that makes the inspection less worth doing. It just keeps a buyer from thinking a clean video is a warranty.
What the real estate caller actually needs
If the deadline is driving it, ask a different set of questions. Who is the inspection for, the buyer or the seller. Is an agent coordinating access, and is the property occupied or vacant. What is the date the report has to exist by. Does the caller need the raw video file, a written summary, still images, or all three, and who does it get sent to. Is a locate needed, or only if something looks wrong.
Do not tell the caller what has to be disclosed, what a contract requires, or what a lender will accept. Those vary and they are not your call to make. Capture the questions and let the parties sort it out. Your job on the phone is to get the technician there with the right equipment, enough time on the schedule, a way into the property, and a clear idea of what document has to exist when they leave.
It also helps to say what comes after the inspection. If the finding is buildup rather than structural damage, the fix may be a cleaning, and drain cleaning versus hydro jetting covers that decision. If the line is original and failing along its length, the conversation starts looking like the one in whole-home repipe consultation calls.
These calls do not wait for business hours
Sewer calls arrive at bad times by definition. The floor drain backs up on a Sunday afternoon. The buyer realizes on Thursday evening that the contingency runs out tomorrow and starts working down a list of plumbers until somebody picks up. Neither of those people leaves a voicemail and waits patiently.
That is the slot Answara covers. It answers the call, runs the intake as an actual conversation (active problem or real estate deadline, symptom pattern, house age, cleanout location and access, parking, dogs, the report the caller needs), and puts a booked appointment on the calendar with the details attached instead of a name and a callback request. A briefed answering service does the same work if the operators are trained on your fields rather than taking generic messages. Neither one diagnoses the pipe. That happens when the camera goes in.
