How to become a plumber on Long Island

The short version
  • Plumbers learn as apprentices: a paid job under licensed plumbers, plus classes.
  • The union for Nassau and Suffolk is Plumbers Local 200 in Bohemia. It recruits apprentices only at certain times.
  • Non-union plumbing shops also hire and train apprentices directly.
  • Licenses come later. In Suffolk the county issues them; in Nassau your town or village does.

Every building needs water in and water out, so plumbers are needed in every economy. The work is hands-on, varied and well paid once you’re trained. Here’s how to get started on Long Island.

How plumbers learn

Plumbing is learned through an apprenticeship. It’s a paid job where you work alongside experienced plumbers and take classes on the side. In a New York State registered apprenticeship:

  • You earn a paycheck while you learn, and training is usually free to you.
  • Classes are usually in the evening at a trade school, community college or BOCES.
  • Programs last one to six years depending on the trade.
  • You need to be 18, or 16 to 17 with a parent’s approval, and usually a high school diploma or equivalent.

The union route: Plumbers Local 200

Plumbers Local 200 covers Nassau and Suffolk and is based at 375 Central Avenue in Bohemia. It doesn’t take applications all year; it holds recruitments for a set number of spots. In its past recruitments, applicants had to:

  • Be at least 18.
  • Have a high school diploma or equivalency (such as a GED or TASC).
  • Live in Nassau or Suffolk when they applied.
  • Have a valid New York State driver’s license.
  • Pass a drug test after being selected.

Applications were taken in person at the Bohemia office. Past notices also said apprentices buy their own textbooks for classes, about $200 a year. These details come from older recruitment notices, so call Local 200 at (631) 567-3083 or check the state’s apprenticeship announcements for the current rules and dates.

Past recruitments were for 20 spots at a time, so they’re competitive. Don’t wait on one. Work at a plumbing shop in the meantime, and the experience will help your application.

The non-union route: a plumbing shop

Plenty of plumbing shops on Long Island hire apprentices and helpers directly. You might start on service calls, new construction or remodels. Before you say yes, ask:

  • Is this a state-registered apprenticeship? If not, how is my training documented?
  • What’s the pay now, and how does it go up as I learn?
  • Who pays for classes?
  • Will I work under a licensed plumber?

Either way, log every day you work. Years of documented experience are what you need for a license.

Licenses on Long Island

You don’t need a license to start as an apprentice. You’ll need one later to run jobs on your own:

  • Suffolk County licenses master plumbers through a county plumbing licensing board. The county code requires applicants to be at least 21 with seven years of experience in the trade within the past ten years.
  • Nassau County leaves plumber licensing to its towns, cities and villages, so the rules depend on where you work.

What you can do this week

  1. Find your diploma or GED, and make sure your driver’s license is current.
  2. Call Local 200 to ask about the next recruitment.
  3. Visit a plumbing shop. Seeing a crew at work is the fastest way to know if this trade is for you.
