Plumbing Trade References (FBC-Plumbing & handbooks)
The Florida Building Code — Plumbing and Fuel Gas volumes plus the standard trade handbooks: where sizing rules, fixture requirements, and DWV provisions live.
274 questions in our bank cite this reference.
The one thing to know
Plumbing code questions are chapter questions: water supply, DWV, vents, and fixtures each live in their own chapter. Learn the chapter map and the definitions chapter cold.
Your tab set
Florida exams allow pre-tabbed, highlighted references. Build these tabs before exam day, in book order.
Permit scope, rough-in and final inspection sequence
Defined terms
Clearances, accessible fixtures, overflows, materials
Safety devices (T&P relief), safe pans, drain terminations
Sizing, backflow prevention devices, pressure limits, thermal expansion, lead-free rules, pipe joints
DFU sizing, slopes, cleanouts, backwater valves, sumps & ejectors; storm/sanitary separation (Ch. 11)
Vent methods (wet, circuit, island), trap arm distance, termination
Trap seals, prohibited traps, grease interceptors
Gas piping sizing & testing, sediment traps, CSST bonding, venting categories, regulators
Category 1 piped gas/vacuum systems: zone valves, alarms, outlet pressures, brazing & verification
Class I/II/III standpipes, hose connections, fire department connections
Collector orientation & tilt, open vs closed loop, heat exchangers, freeze and scald protection
Isometrics and symbols, grade & fall, fitting takeoff, gas demand (Plumbers Handbook / Mathematics for Plumbers)
Highlight the question, underline the answer
Don't just tab your books — mark them as you practice. Every time a question sends you into a reference, leave a two-part mark behind: highlight the passage the question is about, and underline the exact words that answer it. Do this through your whole question bank and the book turns into a map of the tested material — so on exam day you recognize the spot, not just the section.
- 1
Highlight what the question asks about
When you look up a practice question, highlight the sentence or table the question turns on. That block is now a visual landmark you'll spot on a fast flip.
- 2
Underline the exact answer
Inside the highlight, underline the specific number, deadline, or phrase that is the answer — with a fine-tip pen. Highlight = the topic; underline = the fact.
- 3
Color-code by what trips you up
Use one highlighter color for deadlines and numbers, another for definitions, a third for the answers you got wrong twice. Your weak spots become the brightest marks in the book.
- 4
Let your tabs and marks compound
A tab gets you to the chapter; the highlight gets you to the paragraph; the underline gets you to the answer. Built up across a full question bank, that three-layer trail is the open-book skill the exam actually tests.
The reference lists allow underlining with pen or highlighter, bar handwritten and typewritten notes in the books, and bar making any marks during the exam — so every mark goes in before you walk in, and none of them can be written notes.
Navigating under time pressure
- FBC-Plumbing Chapter 2 is definitions — defined terms decide trick questions.
- Fuel gas questions route to the separate FBC — Fuel Gas volume, not the plumbing volume.
- Math-heavy questions (grades, offsets, gas demand) come from the handbook side, not the code.
