AI agents for plumbing

A plumbing shop runs on the phone. A burst pipe, sewage backing up a floor drain and a dripping faucet all land on the same line, often after hours. The owner or master plumber pulls permits under their licence, prices the work and handles the money. Service plumbers diagnose and repair fixtures, drains, water heaters and piping, then write up what they did. Apprentices log years of supervised hours. A CSR or dispatcher books, reschedules and keeps the board moving, and a bookkeeper deals with invoices and supplier bills.

The paperwork trails behind the trucks. Permits wait to be closed after a water heater install, and the warranty never gets registered. Annual backflow tests come due and nobody reminds the customer. Supply house tickets arrive at month end with no job number. Customers call back asking what was replaced and where the shut-off is.

An agent works from the shop's own job system and price book, and hands the office drafts and lists to check.

• Sorts after-hours calls by urgency and pages the on-call plumber, using a fixed safety script the owner wrote.
• Builds the yearly backflow-test due list from last year's tests and prepares the results for the utility's portal.
• Turns a plumber's sewer camera notes into a plain report for the homeowner: start point, distance from the cleanout, defect and recommendation.
• Drafts good, better and best water heater options from the owner's price book.
• Closes out installs by tracking the permit, the inspection and the manufacturer warranty registration.
• Matches supplier bills to jobs, flags parts that were bought but never billed, and builds each van's restock list from what it invoiced.
• Answers customer questions about the water utility's lead service line letters, from approved wording only.

Diagnosis, pricing and anything done under the licence stay with the plumber: permits, gas work and backflow test results. The agent never says what a pipe is made of without a plumber having seen it. A gas smell is never triaged by software; the script tells the caller to leave on foot, avoid sparks and phones inside, and call 911 and the gas company from outside. Texts to customers need A2P 10DLC registration and documented opt-in. Addresses, door codes and photos inside homes stay in the owner's systems, and nothing reaches a customer until the owner or office has approved it.
