These are real pages from the book. The table of contents is the full one: 9 parts and 65 topics.
It's 10 p.m. and a practice question asks: a head sits 10 inches from a beam. Can the deflector go above the bottom of the beam? You've hung heads next to beams for years. And you still hesitate.
The code gives it to you as a table and a paragraph: distance from the beam in one column, inches in the other. Nothing shows you the beam, the head and the gap, so by morning the numbers have blurred.
In this book the beam rule has its own page: the beam drawn in section, the head beside it, the horizontal distance and the deflector height marked, and the rule in a box: under one foot away, the deflector stays at or below the bottom of the beam.
Same with K-factor and Q = K√P, the beam rule, hanger spacing, equivalent lengths and the fire flow test on N^1.85 paper. Each one gets its own page.
You look at the drawing, it makes sense, and you answer without going back to the code book.
Reading the plans, hazards and system types, the sprinkler itself, spacing, obstructions, piping and bracing, hydraulic calcs, water supply and working plans: 69 pages, all illustrated.
Think of it this way:
You're in the exam, or across the table from the plan reviewer. A 5-foot-wide duct runs right under your heads. Do you need sprinklers below it? You need the answer now, not after twenty minutes in the code.
You open the page on wide obstructions and see the duct drawn under the ceiling, the heads above it, the 4-ft line marked and the extra head underneath.
Same with the beam rule, the three times rule, hanger spacing, the density/area curves and the fire flow test: each one on its own page.
Sprinkler Layout Illustrated is 9 parts and 65 topics, all drawn, ending with a full worked hydraulic calc, common layout mistakes drawn wrong and right, and an exam-day quick reference.
What you see drawn, you don't have to memorize.
You open any plan and know where to look: how the NICET layout exam is mapped, how NFPA 13 is organized, scale, fire protection symbols, the reflected ceiling plan, sections and ceiling heights.
The occupancy hazard classes, classifying a real building, the density/area curves, hose stream allowance, wet, dry, preaction, deluge and antifreeze systems.
The parts of a sprinkler, K-factor and Q = K√P, temperature ratings and colors, upright, pendent and sidewall, response types, ESFR and CMSA.
Coverage area S × L, maximum coverage by hazard, distance to walls, minimum distance between heads, deflector distance, sloped ceilings, small rooms and concealed spaces.
You stop guessing around beams, ducts and columns: why obstructions matter, the beam rule, the three times rule, ducts and wide obstructions, clearance to storage, open trusses and soffits.
Pipe materials and C-factors, mains and branch lines, pipe schedule sizing, hanger spacing, armovers, hanger components, seismic sway bracing and flexible couplings.
You run every calc in the same order: design area, how many heads flow, the remote head, Hazen-Williams, equivalent lengths, elevation, node to node, balancing, and a full worked example.
The fire flow test, plotting on N^1.85 paper, available flow at any pressure, underground and backflow losses, fire pumps, FDCs, standpipes and tanks.
Your plans go out complete: what goes on the working plans, riser details, the hydraulic data sign, acceptance testing, and an exam-day quick reference. The most common mistakes, before and after, come in the bonus book.
At the end of the book: A full worked hydraulic calc, riser and hydraulic data sign details, and an exam-day quick reference.
Exam-style questions on hazard classes, spacing, obstructions and hydraulic calcs, each answer worked out step by step so you see where the number comes from.
The errors plan reviewers flag most often, each drawn wrong and then right, so you catch them on your own drawings before anyone else does.

You already know the pipe. The book shows you the design side the way you see the job: one drawing per topic, with the rule and its number next to it.
You review by part, from hazard classes to the six-step hydraulic calc, and finish with the exam-day quick reference and the practice book.
You keep it next to the code to check a spacing, an obstruction or a C-factor at a glance, and catch the common mistakes before the plans go out.

Yes. It's written for people who already know the field side, not for beginners. It covers the layout core from Level I up: reading plans, hazard classes, spacing, obstructions, piping, and the hydraulic calc step by step with supply curves and a full worked example. Rack storage and in-rack design aren't covered in depth: check the index against your level's content outline.
Code values are checked against the current edition of NFPA 13 (2025), with cross-references to NFPA 14, 20 and 24. The exam scope follows the NICET Water-Based Systems Layout content outlines. If your exam references an earlier edition, check values against the edition it lists.
No. It's an independent illustrated study book. It's not published by or affiliated with NICET or NFPA, and it doesn't reproduce the standard: it explains and draws the rules in its own words. It doesn't give you a certificate or NICET credit: certification only comes through NICET's own exams and requirements.
No. Keep NFPA 13 and your company notes. What this adds: each rule drawn on its own page, in the order you study it, with the numbers in one box, so you find the beam rule or a C-factor at a glance instead of digging through chapters. It doesn't replace NFPA 13, formal training, or the judgment of the engineer of record or the AHJ.
No. They're written for this book, in exam style, with every answer worked out step by step. They're not official questions from any exam.
The book and the 2 bonus books come as PDFs by email.
No. It's a one-time payment.
Yes. It's a printable PDF: you can print the whole book or just the pages you want to keep at the office.
