After completing an apprenticeship program, plumbers, pipefitters, and steamfitters are considered to be journey workers, qualifying them to perform duties on their own. Plumbers with several years of plumbing experience may earn master status by passing an exam. Some states require a business to employ a master plumber in order to obtain a plumbing contractor’s license.

Much of the plumbing work in populated areas is regulated by government or quasi-government agencies due to the direct impact on the public's health, safety, and welfare. Plumbing installation and repair work on residences and other buildings generally must be done according to plumbing and building codes to protect the inhabitants of the buildings and to ensure safe, quality construction to future buyers. If permits are required for work, plumbing contractors typically secure them from the authorities on behalf of home or building owners.[citation needed]
"We have found our plumber for life! Jim is awesome! We just bought a house with a leak in the foundation, and in spite of the complicated and extensive nature of the repairs needed, Jim quoted us an incredibly reasonable price. Having just closed on a house, though, we were extremely short on funds, and so to help us out, Jim did a temporary fix for much less, and even though he was going above and beyond and doing this extra work for us, he said he'd even deduct the cost of that repair from the total of the final, permanent repair, when we had that done!! I can't say enough good things about him - there's much more, but I don't have room!"
With all the freezing weather our city has had, my dad had a problem with his water pipes and I told him to call BL plumbing service. From the first phone call he made, the company gave him the most remarkable customer service. The dispatcher promptly made an appointment for him and within a couple of hours 2 workers were at his home working on the problem and fixing his pipes! The workers were very kind, helpful and extremely courteous to my dad. Not only was the work done quickly, but also, the cost of the repair was more than fair. I am so grateful for the service that was given to my dad and I will highly recommend this company to anyone needing plumbing work.

Galvanized steel potable water supply and distribution pipes are commonly found with nominal pipe sizes from 3⁄8 inch (9.5 mm) to 2 inches (51 mm). It is rarely used today for new construction residential plumbing. Steel pipe has National Pipe Thread (NPT) standard tapered male threads, which connect with female tapered threads on elbows, tees, couplers, valves, and other fittings. Galvanized steel (often known simply as "galv" or "iron" in the plumbing trade) is relatively expensive, and difficult to work with due to weight and requirement of a pipe threader. It remains in common use for repair of existing "galv" systems and to satisfy building code non-combustibility requirements typically found in hotels, apartment buildings and other commercial applications. It is also extremely durable and resistant to mechanical abuse. Black lacquered steel pipe is the most widely used pipe material for fire sprinklers and natural gas.


Plumbers in Australia have licensing requirements that differ from state to state but it is generally accepted a 4-year apprenticeship with a further minimum experience of 2 years (6 years total) and a further curricular requirement as a benchmark for licensing. Licensed plumbers are also expected to maintain minimum relevant training requirements to maintain their plumbing license
