Washington Plumber Continuing Education — Hours, Categories, and Deadlines

How Many CE Hours Washington Requires

Washington's continuing education requirements vary by license level, and the hour splits trip people up more than the total count.

Trainees need 8 hours of L&I-approved CE annually, submitted before their trainee card renewal date. Within any continuous two-year period, the CE portfolio must include at least 8 hours of plumbing code training, at least 4 hours of industry-related electrical (IRE) training, and the remaining 4 hours from plumbing code, IRE, or industry-related plumbing (IRP) courses.

Journey-level (PL01) and specialty plumbers renewing their three-year certification need 24 hours of approved CE before the renewal cycle. The portfolio must include at least 12 hours of plumbing code training and 4 hours of industry-related electrical (IRE) training, with the remaining 8 hours selected from plumbing code, IRE, or industry-related plumbing (IRP) courses.

The category split is the part that causes problems. If you've completed 8 hours of pure plumbing code training but zero IRE hours, you haven't met the requirement — even though your total hours hit the number. L&I's system tracks categories, not just totals.

What Counts as Approved CE

L&I maintains a list of approved continuing education providers and courses. The CE must be delivered by an L&I-approved provider, and the provider is responsible for reporting your completion directly to L&I. You don't self-report CE hours — if your provider doesn't submit the record, L&I won't credit you.

Approved CE categories break down as follows:

• Plumbing code — UPC provisions, Washington state amendments (WAC 296-400A), code updates, and technical installation standards
• Industry-related electrical (IRE) — electrical systems that intersect with plumbing work (pump motors, water heater electrical connections, control circuits)
• Industry-related plumbing (IRP) — broader trade topics like green plumbing, water conservation, safety practices, and business management for plumbers

Exam prep courses, manufacturer product training, and general safety certifications (OSHA 10, first aid) typically do not count toward L&I CE requirements unless the specific course is on L&I's approved list. Check the provider's approval status before enrolling and paying.

The Deadline That Matters

For trainees, CE hours must be completed and reported to L&I before your annual trainee card renewal date. If the hours aren't on file when L&I processes your renewal, your card won't renew — and working with an expired trainee card means those hours don't count toward your certification pathway.

For certified plumbers, the CE must be completed before the three-year certification renewal date. Late renewals trigger an immediate double-fee penalty ($485.40 instead of $242.70), and your certification is suspended until the renewal processes. During the suspension, you can't legally perform plumbing work.

The practical risk isn't just the penalty fee. If you're a designated plumber for a contractor, your personal certification suspension cascades up to the contractor's registration — the contractor can't pull permits or take new work until the designated plumber's credential is restored.

How to Verify Your CE Status

L&I's online portal lets you check which CE hours have been reported against your certification record. Log in with your individual plumber certification number and verify:

• Total hours reported in the current renewal period
• Category breakdown (code, IRE, IRP)
• Provider name and course completion date for each reported session

If a course you completed isn't showing up, contact the provider first — they're responsible for reporting. If the provider confirms they reported and L&I's system doesn't reflect it, contact L&I's Plumbing Program directly with your completion certificate.

Don't wait until your renewal month to check this. CE providers submit completions electronically, and L&I's system can take up to one week to reflect them.

Planning Your CE Calendar

The simplest approach: complete your CE hours in the first half of your renewal period, not the last few months. This gives you a buffer if a course gets canceled, a provider is slow to report, or you realize you're short on IRE hours and need to find an approved electrical course.

For trainees renewing annually, that means knocking out your 8 hours within the first six months after your last renewal. For journeyman and specialty plumbers on three-year cycles, aim to have all 24 hours completed at least six months before your renewal date.

The Washington Plumber License Guide includes a CE tracking worksheet that maps your hours against the category requirements and flags gaps before they become a deadline problem.
