A Simple Plan to Prepare for the Kansas Journeyman Plumber with Gas (ICC KGR, 2018 IPC/IFGC) Exam

Step one is the books. This is an open-book exam, so the references on the bulletin's list are what you'll work from, while you study and in the exam room. Get the editions the bulletin names.

Step two is learning your way around them. Go through each book's table of contents and index until you know where the major subjects are. You don't need to memorize the books. You need to find things in them.

Step three is marking them up. Highlight the sections you use most. Check the bulletin's rules on tabs and markings before you add any.

Step four is timed practice. Our practice exams run on a clock, so you get used to the real exam's pace: about 2 minutes 34 seconds per question.

Along the way, give the most time to the biggest topics. Administration General Regulations and Gas Piping make up 53% of the exam.

The last step is consistency. Keep practicing until you pass several practice exams in a row. That's the signal you're ready.

Reference Books for the Kansas Journeyman Plumber with Gas (ICC KGR, 2018 IPC/IFGC) Exam

Where to get them:

• IFGC 2018

On Test Day

Go through the exam at a steady pace. On your first pass, answer the questions you know and bookmark the ones you don't. Every exam lets you come back to bookmarked questions, but some lock the ones you've seen once you take a break, so finish your bookmarks first.

On your second pass, return to your bookmarks one at a time. You have 3 hours for 70 questions, which is about 2 minutes 34 seconds per question, so keep moving and don't let one question hold you up. Before you finish, answer anything you skipped. A blank can't earn a point.

Study Tips

Our practice exam is specifically designed to mimic the testing conditions at all exam centers. While untimed PDF study guides might help with studying, they don’t prepare you for the challenge of managing your time during an actual test.

Give yourself at least three to six weeks. Use your exam's candidate bulletin as your roadmap for what's tested, and spend your time on finding-it-fast skills over rote memorization. In practice, aim for three clean passes at 80% or higher — setting your practice bar above the real cut score gives you a comfortable margin on test day.

Don't let the clock rattle you. It's easy to feel overwhelmed when facing a page full of questions, a racing mind, and a ticking clock. Stay calm and stick to your planned pace. If you've been monitoring your progress consistently, you'll have enough time to finish. Even if the final minutes feel rushed, as long as you have only as many questions remaining as you should at that point, you're exactly where you need to be.

Your license won't show your exam score. Whether you ace it or squeak by, you walk out licensed either way — as we like to say, C's get licenses. Aim to pass, not to be perfect, and don't tally your score as you go; that pressure only drags your performance down.

Sample Kansas Journeyman Plumber with Gas (ICC KGR, 2018 IPC/IFGC) Practice Questions

Here are a few questions from our practice question bank, each with its answer and reference.

Sample 1 — Water Supply and Distribution

Question: You are setting a new water service in the same trench as the building sewer. The sewer piping is NOT constructed of a material listed in the building sewer pipe table, and the water service will run parallel to it at the same elevation. What horizontal separation is required between the two pipes?

• A. 5 feet of undisturbed or compacted earth
• B. 3 feet of undisturbed or compacted earth
• C. 12 inches of undisturbed or compacted earth
• D. 10 feet of undisturbed or compacted earth

Correct Answer: A

IPC 603.2 requires that where a building sewer in a common trench is not of a material listed in Table 702.2, the water service pipe and the sewer be separated horizontally by not less than 5 feet of undisturbed or compacted earth. The separation does not apply at crossings that are sleeved, or where the bottom of the water service is at least 12 inches above the top of the sewer.

Reference: IPC 2018 Chapter 6, Section 603.2 (Separation of Water Service and Building Sewer)

Sample 2 — Sanitary Drainage

Question: You are a master plumber supervising a crew installing a building sewer that is 6 inches in diameter and 280 feet long. How many cleanouts are required along this run at a minimum?

• A. 4
• B. 2
• C. 1
• D. 3

Correct Answer: D

Per IPC Section 708.1.2, building sewers smaller than 8 inches shall have cleanouts at intervals of not more than 100 feet. Per Section 708.1.3, a cleanout is also required at or near the junction of the building drain and sewer. For a 280-foot run, cleanouts are needed at intervals of 100 feet (at approximately 0 ft/junction, 100 ft, and 200 ft), requiring a minimum of 3 cleanouts to serve the entire length.

Reference: IPC 2018 Sections 708.1.2 and 708.1.3

Sample 3 — Plumbing Vent Requirements

Question: In a common vent arrangement where fixture drains connect at different levels, which fixture is prohibited from being the upper fixture?

• A. Shower
• B. Water closet
• C. Bathtub
• D. Lavatory

Correct Answer: B

Per IPC Section 911.3, where fixture drains being common vented connect at different levels, the upper fixture shall not be a water closet. The vertical drain connecting the two fixture drains is considered the vent for the lower fixture drain.

Reference: IPC 2018 Section 911.3

Sample 4 — Traps, Interceptors, and Separators

Question: Which of the following is a prohibited trap type with NO exceptions allowed under the plumbing code?

• A. Drum trap
• B. Traps constructed of approved corrosion-resistant material with interior partitions
• C. S-trap
• D. Traps with interior partitions integral to the fixture

Correct Answer: C

Per IPC Section 1002.3, S-traps are listed as prohibited traps with no exception. Drum traps are also prohibited but have an exception allowing their use as solids interceptors or for chemical waste systems. Traps with interior partitions that are integral with the fixture or constructed of approved corrosion-resistant material are permitted.

Reference: IPC 2018 Section 1002.3
