"Learn a trade" has become common advice for people worried about AI, and plumbing is usually near the top of the list. The data backs that up: plumbing scores among the lowest of all jobs for generative AI exposure, and US projections expect steady growth. Where AI does touch plumbing is mostly the business around the job, and the homeowner trying to fix a leak with a chatbot's help.
The short answer: the evidence so far does not point to AI replacing plumbers. The ILO's 2025 index classes plumbers and pipe fitters as not exposed to generative AI. The US Bureau of Labor Statistics projects employment of plumbers, pipefitters and steamfitters to grow 7 percent from 2025 to 2035, driven by new construction and by maintaining and repairing plumbing in existing buildings. No projection is certain.
Why plumbing is hard to automate
No two plumbing jobs are quite the same. The pipe is behind a wall, under a slab or in a crawl space; the building is decades old and was changed by three previous owners; the customer describes the problem as "a noise". The work means diagnosing by sight, sound and touch, cutting and joining pipe in awkward spaces, and making a judgment about what will hold. That mix of physical work and on-the-spot judgment is why the ILO scores it so low.
A plain note on robots: the ILO index measures generative AI, the kind that produces text, images and code, not robotics (ILO Working Paper 140, 2025). It says a chatbot cannot do a plumber's job. It does not forecast what robots might do, and neither does this page.
How exposed plumbing and related trades are
How to read the table: the mean task score runs from 0 to 1, and the band is the ILO's grouping, from not exposed through minimal exposure to gradient 4, the highest (ILO Working Paper 140, 2025). More on the method in will AI take my job?
| Occupation (ISCO-08) | ILO category | Mean task score (0 to 1) |
|---|---|---|
| Air Conditioning and Refrigeration Mechanics | Not exposed | 0.21 |
| Plumbers and Pipe Fitters | Not exposed | 0.18 |
| Agricultural and Industrial Machinery Mechanics | Not exposed | 0.17 |
| Carpenters and Joiners | Not exposed | 0.13 |
All of these building and repair trades sit in the ILO's lowest category, far below office jobs.
The job outlook
The BLS projects about 42,000 openings a year for plumbers, pipefitters and steamfitters, many to replace workers who retire or change occupations. It says demand will come from new construction and from the need to maintain and repair plumbing systems in existing homes and other buildings, and that employment of sprinklerfitters is expected to increase because building codes in all states require fire suppression systems (BLS Occupational Outlook Handbook).
Unlike electricians, whose demand the BLS links partly to AI and data centers, plumbing demand rests on the steady need to build, maintain and repair the buildings people already use. See will AI replace electricians? for the contrast.
How AI is changing the business side
For a plumbing business, especially a small one, the office is where AI tools fit:
- Answering calls and messages after hours and booking appointments.
- Writing quotes, invoices and follow-up messages.
- Turning a customer's photos and description into notes before the visit.
- Ordering parts and tracking stock in the van.
- Writing website text and replying to reviews.
These save time on paperwork but do not change the job on site.
When customers ask a chatbot first
More homeowners now describe a problem to an AI tool before calling anyone. That can help with simple things, such as finding a shutoff valve, but AI can give confident and wrong instructions (NIST AI 600-1). For plumbers, it means more customers arrive with a theory about the problem, and sometimes with a repair that needs redoing. Explaining what is actually wrong, and why, becomes part of the job. See checking AI output.
Getting into the trade
According to the BLS, most plumbers, pipefitters and steamfitters learn the trade through a 4- or 5-year apprenticeship, with about 2,000 hours of paid on-the-job training a year plus some technical instruction, and most states and some localities require plumbers to be licensed.

Pay and how to get in
The US Bureau of Labor Statistics puts the median annual pay for plumbers pipefitters and steamfitters at $63,800 in May 2025, against $50,980 for all workers. The typical education needed to enter is: high school diploma or equivalent. See how this job compares in AI exposure by pay and AI exposure by education level.
Questions and answers
Will AI replace plumbers?
Current evidence says no. The ILO classes plumbers and pipe fitters as not exposed to generative AI, and the BLS projects 7 percent US growth for plumbers, pipefitters and steamfitters from 2025 to 2035.
How exposed is plumbing to AI?
In the ILO 2025 index, plumbers and pipe fitters score 0.18, among the lowest of all occupations.
Will robots replace plumbers?
The ILO index measures generative AI, not robotics, so it does not answer this. The varied, hands-on nature of plumbing work makes it hard to automate, and US projections expect growth.
How is AI used in plumbing?
Mostly in the business: booking, quotes, invoices, parts ordering and customer messages. The diagnosis and repair stay with the plumber.
How do you become a plumber?
According to the BLS, most plumbers train through a 4- or 5-year paid apprenticeship, and most states and some localities require plumbers to be licensed.
