Direct answer
A plumbing AI receptionist answers the published company number when you are under a sink, on a roof drain, or closed. It separates an active leak from a water-heater quote, collects the address and shutoff status, and either books a window, builds the morning queue, or transfers you. The caller should never be told to dial a different company number.
Plumbing intents worth their own path
If every inbound call is labeled “service,” the technician still has to redo the intake. Encode the jobs you actually run.
Where is the water, can they shut the valve, is a ceiling or slab involved, is the home occupied? Escalate when your written rule says so.
One fixture vs the whole house, sewage in living space, last service date if they are a customer. This is not a generic clog script.
Tank or tankless, gas or electric if known, age, error lights, and whether they need tonight or a replacement estimate.
These can usually stay with AI: collect scope, city, and preferred window, then book or queue.
Call examples from a real plumbing line
“Water is coming through the dining-room ceiling.”
Ask if they can shut the main or the fixture, get the address, and transfer if active flooding is on your escalate list. Do not quote a drywall repair on the call.
“The toilet is overflowing and the tub is gurgling.”
Backup intent. Ask how many fixtures, whether sewage is on the floor, and whether this is a repeat at the same house.
“No hot water since last night.”
Water-heater intent. Collect type if they know it, pilot or breaker checks you approve, and whether they want a same-day diagnostic or a replacement estimate.
“How much to swap a 50-gallon gas tank?”
Answer only approved ranges or say pricing needs a look at the vent and pan. Book an estimate. Transfer only if they insist on the owner.
“You were here last month and it is leaking again.”
Existing-customer / warranty path. Get the address and last work, then route to the original tech or warranty owner — not a new-lead script.
“Are you open? My rental has no water.”
After-hours or overflow. Occupied property with no water is usually urgent. Landlord vs tenant permission is a field you should ask for.
Intake fields that save a wasted trip
| Ask | Leak | Backup | Water heater |
|---|---|---|---|
| Address / city | Required | Required | Required |
| Can they shut water off | Required | If flooding | If leaking tank |
| Occupied / kids / elderly | For escalate rules | For escalate rules | If no hot water overnight |
| One fixture or whole house | Helps dispatch | Defines backup vs clog | Usually n/a |
| Existing customer | Warranty vs new | Repeat backup history | Prior install notes |
| Wanted next step | Emergency visit vs morning | Emergency vs camera later | Diagnostic vs replace quote |
Do not let the model invent a diagnosis (“it’s definitely the anode rod”). Collect facts, apply your rules, and leave the judgment to the plumber who will stand in front of the fixture.
After-hours plumbing is a rules problem
At 2:00 p.m., a dripping angle stop can wait. At 2:00 a.m., a burst line in an occupied house usually cannot. The receptionist needs your list, not a generic sense of drama.
A practical after-hours policy for many plumbing shops: transfer for active flooding, sewage in living space, or no water in an occupied home. Book or queue everything else. The morning list should already have addresses and shutoff status so the first tech is not starting from voicemail.
Pair this with the after-hours answering guide if you want the broader routing pattern, including next-morning callbacks.
Setup, limits, and what Fix9 will not do
Keep the published number. Forward misses to a Fix9 line. Write service area, hours, brands you will not touch, and the escalate list. Human transfer is available when they ask for you by name or when the rule fires.
Limitations: the AI cannot see the crawlspace, cannot legally decide a gas-leak response, and should not promise arrival times you have not configured. If your current carrier cannot forward unanswered calls, that is a provider limit, not something to paper over in marketing copy.
What to tell the receptionist on day one
Give it your service area, the hours a human is on a truck, and the three plumbing emergencies you actually roll on after dark. For most shops that list is some mix of active flooding, sewage in living space, and no water in an occupied home. Everything else — a slow drip, a quote for a water-heater swap, a camera of a known cleanout — can be a morning slot.
Write the warranty rule. “If they say we were there in the last 30 days, collect the address and last work, then route to warranty — do not sell a new service call.” Write the landlord rule. “If they are a tenant, ask whether the owner has approved the visit.” Write the “do not diagnose” rule. The model should not say a sound is a cartridge or a slab leak.
If you offer memberships or seasonal drain plans, put the approved one-sentence description in the file. If you do not work on gas water heaters, or commercial kitchens, or wells, say that before the receptionist books a drive.
Two conversations worth rehearsing
Leak, occupied, after 9 p.m. Greeting that the shop is closed but someone can help. “Where is the water right now? Can you get to the main shutoff? Is anyone in the home? What is the address?” If the answers match your flood rule, transfer the on-call plumber and keep the notes. If it is a dripping stop under a sink and nobody is at risk, book the first morning window and say so clearly. The caller should know whether a human is coming tonight.
Water heater quote, Tuesday afternoon. “Tank or tankless, if you know? Gas or electric? About how old? Do you have hot water at all, or are you shopping before it fails?” If they have no hot water and your daytime rule books diagnostics, offer the next truck window. If they have hot water and want prices, book an estimate and do not transfer the owner unless they ask. The record should separate “no hot water now” from “replacement shopping.”
Limits plumbers should plan for
AI cannot see the wet drywall or smell the sewer. It cannot decide a gas issue. It should not promise “we will be there in an hour” unless that phrase is a configured, staffed promise — and Fix9 copy does not let us invent response times for you. If your carrier cannot forward unanswered calls, fix that path before you advertise 24/7 answering on the van number.
Pair plumbing intake with missed-call text-back only as a hang-up recovery path, and only with consent. The leak that is still on the line should be answered, not texted.

Frequently asked questions
Can I keep the number printed on the van?
Yes. Keep Your Number is the model. Forward unanswered or after-hours calls to a Fix9 line. Customers keep dialing the published plumbing number.
How should AI treat an active leak?
Collect where the water is, whether it can be shut off, whether the home is occupied, and the address. If your rules say active flooding or a burst line is an escalate, transfer after those fields. Do not ask the model to diagnose the pipe.
What about sewer backups?
Treat backups as their own intent. Ask whether multiple fixtures are affected, whether there is sewage in living space, and whether they are an existing customer. Route or transfer using your backup policy, not a generic “service call” script.
Can it book a water-heater replacement instead of transferring?
Often yes, when you want estimate or install slots on the calendar. Collect fuel type, tank vs tankless if they know it, age, and whether they have no hot water tonight. Transfer if they ask for you by name or if same-night decisions are owner-only.
Will it wake me for every after-hours call?
It should not. Write the escalate list: active flooding, no water in an occupied home, sewage in living space, commercial shutdowns you cover. Everything else becomes a morning queue.
Keep the number people already call.
Add Fix9 as the answering layer: AI answers first, qualifies the request, books or routes the work, and transfers to you when the caller needs the owner.
