Quick answer: Why does a leak detection specialist get paid more than a generalist? Because a leak detection specialist sells something most plumbers cannot: finding the leak nobody else could find. A generalist competes on price with every plumber in town, while a specialist gets called by name, and LeakPro’s training page calls leak detection one of the highest-margin services a plumbing company can add.
Watch Roger Wakefield’s video, then read on for the difference between a generalist and a specialist and why leak detection is a specialty that pays.
What is a generalist plumber?
A generalist takes every kind of call: drains, water heaters, faucets, toilets and whatever else the phone brings. The U.S. Bureau of Labor Statistics (BLS) describes plumbers as workers who install and repair water, gas and other piping systems in homes, businesses and factories.
What is a leak detection specialist?
A leak detection specialist is a plumber or technician trained to find hidden leaks under slabs, behind walls and in the yard, using gauges, listening equipment and line locating tools. The specialist is the one other plumbers call when they cannot find the leak.
Why do generalists end up competing on price?
When every plumber in town can do the same job, the customer has little reason to choose one over another except the price. Roger makes this case in why specialists get paid more in the trades: generalists compete on price, and specialists get referred by name.
Why does leak detection pay?
Because the customer is paying for the finding, not the hours. A hidden leak wastes water every day it runs, and the person who can find it fast without tearing up the house solves a problem worth real money to the homeowner.
- The LeakPro leak detection training page says leak detection is one of the highest-margin services a plumbing company can add.
- The same page says locate jobs commonly bill $250 to $500 or more.
- Roger’s post on specialists says specialists get referred by name, while generalists compete on price.
What does the average plumber earn?
The BLS Occupational Outlook Handbook reports a median pay of $63,800 per year, or $30.67 per hour, in 2025 for plumbers, pipefitters and steamfitters. The median is the middle wage: half earn more and half earn less.
Does the government track pay by specialty?
Not for leak detection. The BLS notes that some fitters specialize as gasfitters or sprinklerfitters, but it does not publish a separate wage for leak detection, so the case for the specialty rests on what the work bills.
How much water does a hidden leak waste?
A lot. The U.S. Environmental Protection Agency (EPA) said in a Fix a Leak Week news release that the average household’s leaks can account for nearly 10,000 gallons of water wasted every year.
That is why homeowners call for help, and why the plumber who can find the leak quickly earns the job. See why fast leak detection saves homeowners from water damage.
What skills does a leak detection specialist need?
LeakPro’s training page lists the skills its class covers, and they are the core of the specialty:
- Slab leak detection: confirming and pinpointing leaks under a concrete slab.
- Line locating: tracing the pipe so you know where it runs before anyone digs.
- Sewer leak isolation: testing cast iron and PVC sewer systems to find where they leak.

How do you become a leak detection specialist?
Get trained on real leaks, not on a customer’s floor. LeakPro’s training is a 2-day class, typically 6 to 8 hours a day, at the LeakPro facility in Wylie, Texas, on a purpose-built training slab with 12 real, live leaks.
Should a plumbing company specialize or stay general?
It does not have to be all or nothing. A company can keep its general service work and add leak detection as a specialty line. Start with how to add leak detection services to your plumbing business, then learn how to price leak detection.
What is the hardest part of specializing?
Saying no. Roger’s post on specialists says the hardest part is being willing to turn down work outside your specialty, so your time and your name stay tied to the work you do best.
