Plumbing is one of the most recession-proof trades there is — water and gas systems always need installing, repairing, and maintaining, and the work can't be automated or sent overseas. It also has one of the clearest paths to owning a profitable business. Here's how to get in.
Pay: $50,000–$100,000+ | Training: 4–5 year apprenticeship (paid) | Union: UA or non-union | Requirement: 18+, HS diploma/GED
Plumbers install and repair the systems that move water, gas, and waste through buildings — supply lines, drains, fixtures, water heaters, and gas piping. Work ranges from residential service calls to large commercial and industrial new construction. There's also specialized work like medical gas, backflow prevention, and hydronic heating that pays a premium.
The job mixes physical work (running pipe, soldering, pressing fittings) with problem-solving (diagnosing leaks, reading plans, meeting code). Service plumbers are out solving different problems every day; new-construction plumbers rough in entire buildings.
Like most trades, the path is a 4–5 year paid apprenticeship. You can go union through the UA (United Association) — apply at your local — or through a non-union contractor. You'll earn a progressive wage, attend classroom training, and accumulate the hours needed to test for your journeyman plumbing license. After more experience you can earn a master plumber license, which lets you pull permits and run a business.
| Stage | Typical Pay |
|---|---|
| Apprentice (yr 1) | $17–$24/hr |
| Journeyman | $28–$48/hr |
| Master / Service | $40–$60/hr |
| Business owner | $90k–$200k+ |
Service and emergency plumbing pays well because of the convenience premium, and business owners with a few trucks running can do very well.

The downsides are real though — you'll deal with the unpleasant side of the job (sewage, tight crawlspaces), and service work can mean being on call. But few trades offer this combination of security and business upside.
A plumbing apprenticeship takes about 4–5 years of paid work plus classroom training, after which you test for your journeyman license. No college required.
Apprentices start around $17–$24/hr, journeymen earn $28–$48/hr, and master plumbers or business owners can earn $90,000 to $200,000+.
Yes — it's recession-resistant, well-paid, can't be automated or outsourced, and offers one of the clearest paths to owning a profitable trades business.
