Plumber
Installs, repairs and maintains the pipes, drains and fixtures that bring water in and take waste out — work done by hand on sites that are never quite the same twice. Software reaches the quoting, booking and leak-finding around the job; in Singapore the law reserves the work itself for licensed plumbers.
Check what licence you need to carry out plumbing works where you work, and what it takes to get it.
This is not a probability of losing your job. It combines how much of the role's task load is exposed to automation with how far adoption has actually gone — useful for comparing occupations on one consistent basis, and for nothing else.
Written for plumbers who install and repair water supply, drainage and sanitary fittings in homes and buildings. It does not cover pipefitters in heavy industry or the engineers who design large water systems. Singapore's law on who may carry out plumbing works establishes who may do the work, not how it is done or how much of the paperwork around it software now handles. The judgements about tools and software rest on what they can do rather than on a measurement of how widely plumbers use them. Nothing on this page counts plumbers.
What is actually changing#
The unit of analysis is the task, not the job title. A role is not replaced — its task mix shifts.
Each tile is one task. Its size is how much of the job it is; its colour is where the task is heading. Click a tile to see what the judgement does not establish.
This rests on what the tools can do rather than on a record of how many plumbers use them, and they help most on the faults that are hardest to see.
This is one country's law and the state of the technology, not a record of how the work is done; prefabricated plumbing modules made in factories move some of the assembly off site.
This is one country's licensing rule; it fixes who answers for the work, not how thoroughly it is checked, and rules on sign-off differ elsewhere.
This rests on what the software can do rather than on a record of how many plumbers use it, and an accurate quote for an unusual job still depends on someone who has seen the site.
This rests on the nature of the work rather than on a record, and would change if customers came to accept remote diagnosis without anyone coming out.
This is an inference about where the work is heading, not a measurement of how many such devices are installed.

Recent changes#
The Act as published on Singapore Statutes Online, read in the current version. Section 40G(1): an individual must not carry out, or offer or undertake to carry out, any regulated works unless the individual is a licensed plumber or acts under the direct supervision of a licensed plumber. Section 40G(3): a person must not in the course of business provide such works unless they are carried out by licensed plumbers or individuals under their direct supervision; section 40G(5): owners or occupiers who want sanitary works or water service installation works done must only engage such a person. Contravening 40G(1) to (4) is an offence punishable by a fine of up to $10,000, imprisonment of up to 3 years, or both; professional engineers are exempt only for limited design works. Section 2 defines regulated works as sanitary works, limited water service installation design works and water service installation works, and sanitary works to include constructing, altering, repairing and replacing discharge pipes, drain-lines, traps and similar fittings, and installing, fixing, altering, repairing or removing sanitary appliances. The section came in with the Public Utilities (Amendment) Act 2018, which commenced in stages on 1 April 2018, 25 March 2019 and 30 April 2020; the record is dated to the last of these because the Act as read here does not say which stage brought section 40G into force. It establishes who may do this work in Singapore; it says nothing about the tools plumbers use or how many plumbers there are.
Failure, rollback, regulation or cost is suppressing adoption. Can lower an assessment or widen its uncertainty.
What this means for you#
If you are starting out, the hands-on core of the trade — finding faults, fitting and repairing on real sites — is the part least touched by software, and in Singapore the law reserves it for licensed plumbers and those they supervise. What changes is around the job: finding work, quoting and getting paid are moving onto platforms and apps. Get licensed, and learn the detection tools and the smart devices early; they are where the new work is.
Your skill on site is not what the new tools replace; they take over the admin and help you find faults faster. The plumbers these changes favour are licensed, use the booking and detection tools well, and can supervise others — because the law makes the licensed plumber answerable for the work.
Your options#
Four directions, each with its real constraints and one thing you can test this week. Continuing as you are is a legitimate choice — it just has to be a chosen one.
Stay on the tools, licensed
The installation and repair work is hand work on varied sites, and in Singapore the law allows only licensed plumbers, or people under their direct supervision, to carry it out.
The work is physically demanding over a long career, and booking platforms can push prices down for routine jobs.
Check what licence you need to carry out plumbing works where you work, and what it takes to get it.
Specialise in leak detection or smart water systems
Finding hidden faults and installing connected devices both reward skill with new tools, and building owners pay to avoid water damage.
The equipment costs money, and the specialist market is smaller than general repair work.
Price one piece of leak-detection equipment and find out how local specialists charge for a detection visit.
Move into supervising or running a plumbing business
Businesses that provide plumbing works must ensure a licensed plumber carries them out or directly supervises them, which makes an experienced licensed plumber the person the business cannot do without.
Running a business means estimating, managing people and cash flow — a different set of skills from the work itself.
Find out what a business needs, where you work, to offer plumbing works legally, and who in it must hold the licence.
Common questions#
Not the work on site. Installing and repairing pipes and fittings is hand work in cramped, varied spaces that current robots do not do, and in Singapore the law says an individual must not carry out regulated plumbing works unless licensed or working under a licensed plumber's direct supervision. Software is changing the parts around the job — quoting, booking, invoicing — and tools such as drain cameras and smart meters help find faults faster.
We do not answer that with a number of years, and for this job there is a signal you can check yourself: whether the law where you work still requires a licensed person to carry out plumbing works. As long as it does, software changes how you find work and faults rather than whether you are needed. Watch for machines that can do repairs inside real buildings without a person, and for any change to who may lawfully carry out the work.
It helps narrow the search. Drain cameras, acoustic and thermal detectors and smart meters that flag unusual flow can point to where a fault is, and apps can suggest likely causes from photos. Opening up the wall or drain, deciding what is actually wrong and fixing it is still done on site by the plumber.
In Singapore, yes for the regulated works: the law says an individual must not carry out sanitary works or water service installation works unless the individual is a licensed plumber or acts under a licensed plumber's direct supervision, and owners who want such works done must engage only such a person. Breaking the rule can bring a fine of up to S$10,000, up to three years in prison, or both. Rules differ in other countries.

A company divides its work into functions before it divides it into jobs. These sit in Core delivery (industry-specific) alongside this one — a fact about org charts, not a judgement that they are similar or that they are changing in the same direction.
