Plumbing emergency call triage
Plumbing has a harder emergency boundary than most trades, because water causes damage while the customer waits. Getting the triage wrong in either direction is expensive: treat a burst pipe as routine and you lose the job and the reputation; treat a dripping tap as an emergency and you burn a same-day slot you needed.
The first question is whether water is still escaping
Almost everything else follows from that. A leak that is contained is a scheduling problem. A leak that is running is a damage problem, and every minute of it is money — ceilings, flooring, plaster, and eventually an insurance claim.
So the opening of the call should establish three things quickly: is water escaping now, where is it going, and can the customer stop it. That third question is the one most worth asking, because the answer often reduces the damage more in the next thirty seconds than your arrival will in the next two hours.
Where your rules say so, the AI tells the caller how to isolate the supply before it moves on to booking. A customer who has found their stop tap is in a materially better position than one who has been told a plumber is on the way.
What separates an emergency from an urgent job
Escaping water, no usable toilet in the property, no water at all, or a sewage backup are the categories that usually cross the line, because each one makes a home unusable or is actively causing damage.
Below that sits a large middle band that feels urgent to the customer without being an emergency for you: one of two toilets blocked, a slow drain, a dripping tap, low pressure, a noisy boiler. These need a same-week slot and a caller who feels heard, not a van diverted from a flooded kitchen.
Where exactly you draw that line is yours to set, and it should reflect your capacity rather than a generic template. A one-van operation cannot promise what a six-van operation can, and a triage system that ignores that produces promises you cannot keep.
| Caller describes | Typical class | What the call should do |
|---|---|---|
| Water coming through a ceiling | Emergency | Isolation guidance, soonest window, urgent flag |
| Sewage backing up | Emergency | Same-day, health note on the job |
| No water in the property | Emergency | Same-day, check whether neighbours are affected |
| Only toilet blocked | Emergency in a single-bathroom home | Same-day, ask how many bathrooms |
| One of two toilets blocked | Urgent, not emergency | Next available, no emergency capacity used |
| Dripping tap, slow drain | Routine | Normal slot |
The question most triage scripts forget
How many bathrooms. A blocked toilet is a routine job in a house with two and an emergency in a house with one, and the caller will not think to tell you which they have. It is one question, it takes three seconds, and it changes the classification entirely.
The same applies to who is in the property. No hot water is an inconvenience in most homes and something closer to an emergency where there is a newborn or an elderly resident. If your rules account for that, the AI asks.
What reaches the plumber
The address and access details, the symptom in the caller’s own words rather than a category, whether the supply has been isolated, the classification and why it was made, and previous work at that property.
That last one matters more in plumbing than elsewhere. The third call about the same stack is a different job from a first visit, and a plumber who knows that before arriving does not spend twenty minutes rediscovering it.
