About this app

Study for the NICET Water-Based Systems Layout certification, then keep the
tools. 1,000 practice questions, full-length timed mock exams at the real
sitting lengths, 32 lessons, and hydraulic calculators you will still open on
site after you pass. Everything works offline.

Built by a working fire protection tech, not a content farm.

FULL-LENGTH MOCK EXAMS

The papers run at the lengths NICET actually publishes, not a rounded-off
sample. Level I is 105 questions in 2.5 hours. Level II is 120 in 3.75 hours.
Level III is TWO separate sittings, because that is how NICET runs it: General
Plans at 70 questions in 175 minutes, and Hydraulics & Water Supply Planning at
60 questions in 4 hours. Level IV is 110 questions in 4h 20m. Sitting a paper at
its real length is most of the preparation.

1,000 QUESTIONS ACROSS TWELVE WORK ELEMENTS

Codes and standards, occupancy and commodity classification, water supply and
underground, hydraulic calculations, sprinklers and discharge, spacing and
obstructions, system types, pipe and hangers, storage protection, standpipes and
fire pumps, inspection and testing, and plans and submittals. Every answer
carries the NFPA 13 chapter it came from, so you learn where to look, not just
what to circle.

HYDRAULICS AND FIELD TOOLS

Hazen-Williams friction loss, K-factor and discharge, density/area, water supply
curves and hydrant flow tests, elevation loss, pipe volume, fire pump checks and
a drawing scale tool. Every calculator uses actual internal diameter, not
nominal, because that is where hand calculations usually go wrong.

REFERENCE THAT LOADS INSTANTLY

18 formulas with worked examples, 25 plan symbols, 155 glossary terms and 127
review cards with spaced repetition. No signal required, which matters in a
mechanical room.

FREE AND FULL ACCESS

All 32 lessons are free, permanently. The warm-up quiz and the whole reference
library are free. Full access is a ONE-TIME PURCHASE that unlocks every
full-length mock exam. There is no subscription, no account and no login. You
can also unlock a single full-length exam by watching an ad if you would rather
not pay.

WHO IT IS FOR

Sprinkler fitters and designers sitting NICET Water-Based Layout at any level,
apprentices working toward Level I, and layout techs who want the hydraulics on
their phone instead of on a laptop in the truck.
