A sample question. Tabbed Plumber's bank cites the section for every answer.

Answers you can check.

Every explanation names the section it came from, so you learn where the answer lives instead of memorizing a letter.

  • Find it. Exactly where to look in your book.

  • Report a problem. Flag a question from the answer screen.

Questions people ask

Which codes does Tabbed Plumber cover?

The Uniform Plumbing Code (2021) and the International Plumbing Code (2018), with fuel gas questions from the International Fuel Gas Code. Your licensing board tells you which code and edition your exam uses.

Does it match my exam's format?

You pick the exam you are taking, and practice exams run in that format: the ICC national exams, Kansas, Maryland, Montana, Nebraska, Washington and a UPC exam in the IAPMO format.

How do you know the answers are right?

Every answer cites the code section it comes from and passes a separate blind check before it ships. If you spot a problem, tap Report a problem under the explanation. Fixes ship in updates.

Do I need my own code book?

Yes. Most journeyman exams are open book, and Tabbed Plumber's lookup drills train you to find things fast in your own tabbed book. The app cites sections but doesn't reproduce code text or tables.

Does it work offline?

Yes. Everything works without a connection, on the job site or in the truck. Nothing leaves your phone.

How much is it?

Free to start: 10 questions a day with explanations, plus free calc practice. The Exam Pass is $24.99, a one-time purchase that unlocks everything for both codes. No subscription.

Can it guarantee I pass?

No study tool can. Passing depends on your own preparation. Tabbed Plumber shows a readiness estimate so you can see where to focus.

Is it affiliated with IAPMO or ICC?

No. Tabbed Plumber is an independent study aid, not affiliated with or approved by IAPMO, the International Code Council, PSI, Prometric, Pearson VUE or any licensing board.
