Minnesota Minneapolis Journeyman Plumber with Gas (ICC - 498 - MN - MI) Exam Book Package

Minnesota Minneapolis Journeyman Plumber with Gas (ICC - 498 - MN - MI) Exam Book Package

If you’re preparing for the Minneapolis Journeyman Plumber with Gas exam (ICC 498 MN-MI), your best advantage is working from the same codebooks the exam is built from—and learning how to navigate them fast. This is a trade exam that rewards practical knowledge, code awareness, and confident decision-making on real plumbing and gas piping scenarios. You’re not just proving you can “do the work.” You’re proving you understand what the code requires, how systems must be installed, and how to verify compliance under time pressure.

This Exam Book Package includes the two core references used for Minneapolis journeyman plumber with gas testing: the Minnesota Mechanical and Fuel Gas Code (with the included ASHRAE standards listed) and the 2020 Minnesota Plumbing Code. Together, these books support the major exam topics—fixtures, water supply and distribution, drain/waste/vent, storm drainage, backflow prevention, gas piping, and fuel gas venting—so you can prepare with the same materials you’ll rely on during the open-book exam.

Journeyman plumbing with gas work is broad by nature. On the plumbing side, you’ll be expected to understand drainage and venting principles, fixture requirements, water distribution, storm drainage basics, and backflow prevention intent and application. On the gas side, you’ll be expected to understand gas piping fundamentals, safe installation practices, and venting concepts that protect people and property. This package is designed to help you study those responsibilities in a focused, exam-ready way.

What You Get

• Exam-aligned codebook set: The two primary references used for the Minneapolis Journeyman Plumber with Gas (ICC 498 MN-MI) exam.
• Plumbing + gas coverage in one package: Support for plumbing systems (fixtures, water supply, DWV, storm) plus gas piping and fuel gas venting topics.
• Open-book study advantage: Built to help you learn both the trade concepts and the code-navigation speed that matters on test day.

Exam Details

• Exam Name: Minnesota (Minneapolis) Plumber Gasfitter Journeyman
• Exam ID: 498 (MN-MI)
• Number of Questions: 100 multiple-choice
• Time Limit: 3 hours
• Passing Score: 70%

The exam outline is organized into content areas with weighted percentages. A smart study plan follows those weights so your time goes where the exam places the most points. This isn’t just a reading exam—it’s a time-managed open-book exam—so your preparation should include both concept review and timed “find-it-fast” practice inside your codebooks.

Content areas and weight:

• Plumbing General Knowledge and Regulations: 18%
• Plumbing Fixtures: 5%
• Water Supply and Distribution: 5%
• Drain, Waste, and Vent: 7%
• Storm Drainage: 5%
• Backflow Prevention: 10%
• Gas Piping: 15%
• Fuel Gas Venting: 15%
• Fuel Gas General Regulations: 20%

Notice how heavily weighted the gas side is: Fuel Gas General Regulations, Fuel Gas Venting, and Gas Piping together represent a major portion of the exam. Your study plan should reflect that by giving gas topics frequent repetition—especially code navigation for venting, sizing concepts (where applicable), and general safety and regulation requirements.

Open Book Test

The Minneapolis Journeyman Plumber with Gas (ICC 498 MN-MI) exam is an open book test. Open book is an advantage only if you’re trained to use it. With 100 questions in 3 hours, you cannot look up everything from scratch. The goal is to know the topic well enough to choose the best answer confidently, then use the codebooks to confirm details and move on.

Use these open-book habits while you prepare:

• Build “first-book instincts”: Know when a question is plumbing-code driven vs. fuel-gas-code driven so you open the right book immediately.
• Practice index searches: Speed comes from choosing the right term and letting the index take you directly to the relevant section.
• Train your table and chart navigation: Plumbing and gas questions often point you toward tables, sizing information, definitions, and requirements embedded in structured sections.
• Use “find-and-confirm”: Start with your best answer from knowledge, confirm it in the book quickly, and keep your pace steady.

Pacing tip: 100 questions in 180 minutes gives you an average of about 1.8 minutes per question. That pace is very manageable when you’ve practiced choosing the correct reference quickly and you’re comfortable with how each codebook is organized.

Licensing Steps

Minneapolis requires certain trades to hold a Certificate of Competency card before working in the City. The ICC exam is part of that competency process. While individual situations can vary, candidates typically follow a pathway like this:

1. Confirm the credential you need: If your scope includes plumbing work and gas piping within Minneapolis, verify you need the Journeyman Plumber with Gas competency card.
2. Submit your City application: Apply through the City of Minneapolis competency card process and provide the documentation required for review.
3. Receive eligibility approval: Once your application is accepted, eligibility is provided so you can move forward to testing.
4. Schedule your exam: Minneapolis contractor/trades exams are administered through ICC’s computer-based testing system and scheduled at approved testing centers.
5. Study from the approved references: Prepare using the Minnesota Mechanical and Fuel Gas Code and the Minnesota Plumbing Code—the same references used in the exam outline.
6. Pass the exam and complete remaining steps: After passing, follow the City’s instructions for final competency card issuance and any required administrative steps.

As a journeyman-level credential, this exam is meant to confirm that you can apply requirements consistently. That includes understanding system intent and making correct decisions for installation, repair, and service scenarios that an inspector would evaluate for safety and compliance.

State Requirements

Minnesota’s statewide code framework establishes requirements for plumbing and fuel gas systems, and the City of Minneapolis uses its competency card system to ensure qualified tradespeople are performing and supervising work within the city. For journeyman plumber with gas candidates, the practical expectation is clear: you can install, alter, repair, and service plumbing systems and gas piping work in a way that aligns with adopted requirements.

In real-world terms, this shows up as daily professional responsibilities:

• Plumbing system competence: Understanding drainage and venting intent, water distribution fundamentals, fixture requirements, and storm drainage concepts.
• Backflow prevention awareness: Knowing why backflow protection matters, where it applies, and how compliance is supported.
• Gas piping readiness: Understanding safe installation thinking, materials and connection awareness, and jobsite practices that reduce risk and improve inspection outcomes.
• Venting knowledge: Recognizing venting concepts and the safety purpose behind venting-related requirements in fuel gas work.
• Code navigation skills: Being able to locate the controlling section when questions arise during install, service, or inspection prep.

This package supports that expectation by giving you the core references you’ll use on test day and on the job after you’re certified.

Test Information and Study Materials

The best way to prepare for ICC 498 MN-MI is to study by the exam weights and build your ability to find answers fast. Use the guide below to organize your prep into repeatable study sessions.

Fuel Gas General Regulations (20%)
This is one of the highest-weighted categories on the exam. Your goal is to become comfortable locating general fuel gas requirements quickly in the Minnesota Mechanical and Fuel Gas Code. Study topics as “rule families”—definitions, general provisions, and requirements that guide safe work. For open-book readiness, practice identifying the key term in a question and jumping to the right section through the index.

Plumbing General Knowledge and Regulations (18%)
Treat this category as a scoring opportunity. Journeyman candidates do well here when they understand how plumbing requirements are organized and can quickly confirm definitions, general provisions, and common code-driven decisions. Practice switching between the plumbing code for plumbing questions and the mechanical/fuel gas code for fuel gas questions so you don’t waste time opening the wrong reference.

Gas Piping (15%)
Gas piping questions often test applied trade knowledge: what belongs where, how systems are arranged, and how safe installation decisions are made. The exam rewards candidates who can interpret what a question is really asking—system intent, safety thinking, and correct application—then confirm the code detail quickly.

Fuel Gas Venting (15%)
Venting is heavily weighted because it’s safety-critical. Study with a “why it exists” mindset: venting supports safe operation and proper removal of combustion byproducts. For open-book speed, get familiar with the organization of venting-related provisions and practice locating the right section quickly based on the keywords that appear in questions.

Backflow Prevention (10%)
Backflow prevention is a mid-weighted category that can add reliable points when studied well. Focus on recognizing when backflow protection is needed and how compliance is supported through correct application. Learn the code structure around backflow topics so you can confirm details quickly without reading whole chapters during the exam.

Drain, Waste, and Vent (7%)
Even though it’s a smaller portion, DWV questions can be time-consuming if you aren’t familiar with the code layout. Your goal is to understand the intent behind drainage and venting, then practice locating the supporting rule or requirement quickly. Build comfort with common DWV terminology so your index searches are faster.

Plumbing Fixtures (5%), Water Supply and Distribution (5%), Storm Drainage (5%)
These smaller sections are ideal “quick win” areas when you prepare efficiently. Instead of trying to memorize everything, build a basic working understanding and practice fast navigation. If you can identify the right chapter/topic quickly, these questions become straightforward and help keep your overall exam pace strong.

Practical study plan for a 3-hour open-book exam:

• Start with the biggest buckets: Fuel Gas General Regulations, Plumbing General Knowledge/Regulations, Gas Piping, and Fuel Gas Venting.
• Add backflow as your next focus: It’s a meaningful portion of the exam and usually responds well to structured study.
• Finish with DWV + the smaller categories: Use short, repeated sessions to build familiarity and lookup speed.
• Train with timed drills: Practice 10–15 questions at a time with your books open. Your goal is faster reference choice and faster section location.
