How AI assistants choose who to recommend for sewer line repair
We asked ChatGPT, Claude and Google AI Mode for sewer line repair recommendations 412 times. Here is what they looked for on a plumber's page before naming it to repair a sewer line.
The short answer
Before naming a plumber for a sewer line repair, assistants wanted a camera inspection before any quote. Then they asked whether the fix is a spot repair or a larger section, and lining or digging. They also checked who pulls the permit, who restores the yard and whose side is broken.

What people actually asked
We asked for sewer line repair in four different ways. Here is each one, word for word, with how many of the 412 answers it produced between September 6 and October 14, 2026:
- “Who should I call for sewer-line repair in Tarpon Springs, FL 34689?”118 answers
- “I need sewer-line repair today — I'm in Dunedin, FL. Who can actually come out?”112 answers, asked with five different timings: today, tonight, within the next few hours, first thing tomorrow and tomorrow morning
- “Sewer-line repair near me — I'm in 34683. Who do you recommend?”104 answers
- “I'm looking to get sewer-line repair done in Largo, FL 33770 sometime this month. Who should I get quotes from?”78 answers, asked with five different timings: next month, sometime this month, in the next few weeks, in two weeks and before the end of the month
Together, the 412 answers covered 16 towns in Pinellas County: including Clearwater, Largo, Palm Harbor, Pinellas Park and St. Petersburg. Each town came up in 6 to 46 answers. By assistant: ChatGPT 168, Claude 150 and Google AI Mode 94.
Customers also call it “sewer pipe repair” or “broken sewer line repair”, so use those words on the page as well.
The question underneath all of them
“Is the proposal a localized sewer repair or replacement of a larger section?” Inspection findings should explain the proposed extent of work without assuming every sewer problem needs replacement.
What your sewer-line repair page has to explain
The answers treated a camera inspection as the start of every sewer repair. Assistants told customers again and again to ask for one before agreeing to any method, and to get the video. They wanted the quote to follow what the camera showed, not a guess. A page that explains how the inspection leads to the proposal, with one real finding, shows the plumber diagnoses before quoting.
Assistants also warned that sewer repair can mean many sizes of job. It can be a small spot repair, lining a stretch of pipe, or digging up and replacing a long section. Customers were told to ask which one a quote covers and why. Some noted that not every company offers trenchless work. The page should say which methods the plumber uses and how the choice is made.
The edges of the job came up often. Assistants told customers to ask who pulls the city or county permit, and whether the yard, driveway or sidewalk is restored afterward. Some told customers to check whether the break is on their private line or the city's side, and whether a local rebate applies. The page should explain each of these lines plainly.
What the assistants looked for before recommending anyone
We read all 412 answers to see what the assistants looked for before naming a company for sewer line repair, what they told the customer to ask, and what they said they couldn’t find.
What the assistants told customers to ask
Most common first:
Is there a camera inspection before the quote?
Most answers told customers to ask for a camera inspection before approving any repair, and many said to get the video. Assistants wanted the repair method to match the damage the camera found.
46% of the answers (191 of 412) brought this up.
Ask for a camera inspection of the line first, since the quote should depend on what it shows.
Will the pipe be lined or dug up?
Many answers told customers to ask whether a repair would use trenchless lining, pipe bursting or traditional digging, and why. Some noted a listing did not say whether the company offers trenchless work.
36% of the answers (148 of 412) brought this up.
Ask whether they'd dig or line the pipe, and why.
Is the fix a spot repair or a larger section?
Assistants regularly told customers to ask whether a quote is for a spot repair or a full replacement. They did not want customers sold a whole new line when one section was the problem.
30% of the answers (122 of 412) brought this up.
Ask for the video, because it shows where the problem is and whether the fix is a spot repair, lining or full replacement.
Who pulls the permit?
Assistants often told customers to ask whether the job needs a city or county permit and who pulls it. Several said the contractor should handle it, along with inspection timing.
28% of the answers (117 of 412) brought this up.
Ask whether the city or county requires a permit.
Is the yard, driveway or sidewalk put back?
Answers told customers to ask whether a quote covers restoring the yard, driveway, sidewalk or flooring after the work. Customers comparing lining with digging weighed this heavily.
25% of the answers (101 of 412) brought this up.
Ask whether yard, driveway or sidewalk restoration is covered.
Is the break on the homeowner's line or the city's?
Some answers told customers to check whether the damage is on their private line or the city's side. A few also mentioned city or county rebate programs for private sewer lines.
15% of the answers (60 of 412) brought this up.
Ask whether the blockage is on your private line or the city side.
What the assistants couldn’t find
In 75 of the 412 answers, the assistant said it couldn’t find or confirm something it needed about a company. By assistant: Claude in 72 of its 150, ChatGPT in 2 of its 168 and Google AI Mode in 1 of its 94. As we asked it, Claude usually says what it couldn’t confirm; ChatGPT and Google AI Mode seldom do, so these counts mostly show what Claude couldn’t find. Most often:
- A phone number or other way to reach the company: 47 answers
- When the company could do the work: 19 answers
- Reviews it could check: 17 answers
- A price or how the job is priced: 8 answers
- Whether the company serves the customer’s town or ZIP code: 6 answers
- A license or insurance it could check: 3 answers
Assistants most often could not find a phone number, and often could not confirm whether a company does trenchless work or real sewer repair at all. A page that names its methods and shows a direct number answers what they kept telling customers to ask.
The listing doesn't say whether they do trenchless work, so ask.
Where the assistants sent people
Each answer linked to the pages the assistant relied on. Of the 318 ChatGPT and Claude answers about sewer line repair, this is how many linked at least once to each kind of site:
- A contractor’s own website: 98% (313 answers)
- A directory or review site such as Yelp, Angi or the BBB: 43% (137 answers)
- A manufacturer or home-improvement guide: 9% (28 answers)
- An official license lookup: 6% (20 answers)
A contractor’s own website was the page linked most often, so your site is usually what the customer is sent to read.
Google AI Mode works differently. In 74% of its 94 answers, the links opened Google’s own listing for a business rather than a website. There, your Google Business Profile is the page the customer sees, so it needs the same facts as your site.
The checks behind every recommendation, applied to sewer line repair
Can the customer reach a person?

Your sewer-line repair page checklist
Work through this list on your sewer-line repair page. Each item answers something the assistants looked for above.
- Use “sewer-line repair”, “sewer pipe repair” or “broken sewer line repair” in the page title, the main heading and the first paragraph.
- Say that every sewer repair starts with a camera inspection, and that the customer gets the video before choosing a fix.
- List the repair methods you offer and say when each one fits, including when digging is the right choice.
- Explain how you decide the length of pipe to repair, and show an example where a spot repair was enough.
- Say that you pull the permit and schedule the inspection, and name the cities and counties where you do.
- Say which surfaces you restore under the quote and which are left to the customer or another trade.
- Explain how you show where the homeowner's line ends, and mention any local rebate program you work with.
- Put a direct phone number on the sewer repair page, and say which number to call for a backup.
- Say how soon you can inspect an urgent backup, and how far ahead a planned repair is usually booked.
- Link to recent reviews and point to ones from customers who had a sewer line repaired.
Going further: let assistants see real openings
For planned work like sewer line repair, a useful opening says whether it is for an assessment or the job itself, and whether the customer’s address is covered.
Merchant Context builds custom integrations with scheduling software so customers and AI assistants can read your current availability. Where your system records the job type, service area, duration and crew capacity, the integration can show those details with each opening, so an assistant can match it to the request instead of guessing.
We scope each connection to the software and data you actually have. A displayed opening is not a confirmed booking: the customer still confirms through your normal booking process, and the information is only useful while it is fresh.

Questions owners ask
Does a broken sewer line always need to be replaced?
No. Assistants warned customers not to assume a full replacement. They told them to ask for a camera inspection and to ask whether a spot repair or lining would work. A page should explain how the inspection decides the size of the repair.
What is the difference between trenchless sewer repair and digging?
Trenchless repair lines the old pipe or pulls a new one through without a long trench. Digging opens the ground to replace the pipe. Answers said trenchless means less yard damage but does not fit every line. A page should say which methods the plumber offers and when each fits.
Who is responsible for a sewer line between my house and the street?
Answers said it depends on where the break is and on local rules. Assistants told customers to ask whether the damage is on their private line or the city's side. A page should explain how the plumber shows where the break is.
Which AI assistants did you test?
ChatGPT, Claude and Google AI Mode. Between September 6 and October 14, 2026, they answered 412 questions about sewer line repair: ChatGPT 168, Claude 150, Google AI Mode 94.
Will these changes guarantee a recommendation?
No. Nobody can promise that. These changes supply what the assistants were looking for in our research. Whether they move recommendations for your business is something to measure after they go live.
How we got these numbers
The questions, counts and quotes on this page come from the 412 answers ChatGPT, Claude and Google AI Mode gave between September 6 and October 14, 2026. We asked for sewer line repair in 16 towns in Pinellas County, Florida. We collected them with software rather than the consumer apps, which can answer differently. We counted what each answer mentioned, what it said it couldn’t find and where it linked. Quotes never name a business.
The study figures come from an earlier set of assistant conversations in July and August 2026 across eight trades, coded for the reason each business was included or left out. Counts overlap and are never added together.
