What It Takes to Become a Plumber
When most people think of a plumber, they still picture the outdated stereotype – a disheveled man hunched under a sink with an exposed belt line. But the truth is, that image belongs in the past.
Modern plumbers are highly trained and highly educated professionals. Since the implementation of the International Plumbing Code (IPC) and Uniform Plumbing Code (UPC), the path to becoming a licensed plumber has become increasingly rigorous. Licensing requirements now demand not only hands-on experience but also in-depth technical knowledge, ongoing education, and state certification.
The Journey Begins: The Plumbing Trainee Card
The first step toward becoming a licensed plumber is applying for and obtaining a plumbing trainee card. This allows aspiring plumbers to work on job sites under the supervision of licensed professionals while beginning to accumulate required hours.
All hours must be officially tracked and submitted to the state through notarized affidavits, ensuring that only verified experience counts toward licensure.
Understanding the Plumbing Licenses
Washington State has three primary plumbing license levels:
PL-04 (Residential Service)
- Limited to single-family homes and duplexes. Can service, repair, or replace existing fixtures and piping that are accessible (above floor or outside walls).
- Requirements: 4,000 hours (approximately 2 years).
PL-02 (Residential)
- Includes single-family dwellings, duplexes, and apartment buildings up to three stories.
- Requirements: 6,000 hours (approximately 3 years).
PL-01 (Journey Level)
- No restrictions – can work on all phases of plumbing, including residential and commercial.
- Requirements: 8,000 hours (approximately 4 years), with at least 4,000 hours in a commercial setting.
The Exam and Ongoing Education
After logging the necessary hours, plumbers must pass state exams ranging from 85 to 150 questions – all administered in closed-book, proctored environments. These exams cover complex math, code compliance, safety standards, and much more.
And it doesn’t stop there. Every licensed plumber must complete 24 hours of continuing education every renewal period to stay current with evolving codes, technologies, and safety protocols.
Why This Matters for Homeowners
Working with an unlicensed plumber may seem like a cost saving alternative. Who doesn’t like to save money?
