About the NICET ITWBS Level II Exam
NICET Inspection and Testing of Water-Based Systems Level II certifies Associate Engineering Technicians who, under limited supervision, inspect, test, and maintain wet and dry sprinkler systems, standpipes, fire pumps, private fire service mains, and water storage tanks. The exam was updated June 2, 2025 and is delivered as a 168-question, 185-minute computer-based test at Pearson testing centers. It is open book: NFPA codes are available as searchable on-screen PDFs, or candidates may bring physical copies. Core references are NFPA 25 (2023), NFPA 20 (2022), NFPA 72 (2022), and NFPA 291 (2022). Candidates need at least 2 years of water-based ITM experience plus verified performance measures.

NICET ITWBS Level II Exam Content Outline
Intermediate ITM Tasks (Dry, Wet, Standpipe, Deficiencies)
Dry system ITM: annual partial and 3-year full flow trip tests, quarterly priming water/low air alarm/QOD tests, 3-year air leakage test (40 psi, 2 hr, 3 psi max loss), compressors and nitrogen generators. Wet systems: monthly gauges, 5-year gauge calibration (3% of full scale), semiannual vane/pressure-switch waterflow tests, listed antifreeze, air vents, sprinkler age testing (50/20/15-year triggers). Standpipes: 5-year hydrostatic (200 psi/2 hr) and flow tests, hose valve and PRV testing. Classifying findings as critical, noncritical, or impairments
ITM for Water Supplies
Fire pumps: weekly 30-minute diesel and weekly/monthly 10-minute electric churn tests, annual flow test at churn/100%/150% with a 5% degradation limit, NFPA 20 (2022) curves (churn head max 140%), jockey pump settings, transfer switch tests, batteries and fuel (two-thirds full). Private mains: 5-year flow tests, annual hydrant flushing and lubrication, PIV operation, NFPA 291 (2022) flow testing, classification colors, and pitot calculations. Tanks: 3/5-year interior inspections, monthly water level, quarterly exterior, 40 degrees F minimum water temperature
Internal Obstruction Investigation
5-year internal piping assessment at the end of one main and one branch line, alternative video/nondestructive methods, NFPA 25 14.3.1 investigation triggers (foreign material in valves/pumps, plugged sprinklers, 50% water delivery time increase, extended shutdowns over 1 year), four-point examinations (system valve, riser, cross main, branch line), hydraulic flushing rates for 10 ft/s velocity (390/880/1,560 gpm for 4/6/8 in.), hydropneumatic flushing, MIC, calcium carbonate scale, ice plugs, and zebra mussels
Safety
PPE standards (ANSI Z89.1 head, Z87.1 eye), lockout/tagout under 29 CFR 1910.147 with personal locks, permit-required confined space atmospheric testing order (oxygen, flammables, toxics), 4:1 ladder angle with 3 ft extension and three-point contact, boom lift harness requirements, general industry 4 ft fall protection threshold, relieving stored air/water pressure before opening dry valves, and safety impairment procedures
Communication with AHJs and Customers
Pre-inspection scope reviews and scheduling with customers, notifying owners, alarm monitoring companies, and fire departments before alarm-activating tests and after restoration, NFPA 25 Chapter 15 impairment program (owner-designated coordinator, tags at the FDC and riser, fire watch or evacuation when out of service over 10 hours in 24), record retention (1 year past the next activity of that type; acceptance records for system life), and complete ITM reports with deficiency classification

Frequently Asked Questions
How many questions are on the NICET ITWBS Level II exam?
The updated exam released June 2, 2025 has 168 questions with a 185-minute time limit, delivered by computer at Pearson testing centers. That works out to roughly 66 seconds per question, so fast code navigation is essential even though the exam is open book.
Is the NICET ITWBS Level II exam open book?
Yes. NFPA codes and standards are provided on screen as searchable PDFs during the CBT exam, and candidates may alternatively bring physical copies of the referenced books. The primary references are NFPA 25 (2023), NFPA 20 (2022), NFPA 72 (2022), and NFPA 291 (2022).
What experience is required for NICET Level II in Inspection and Testing of Water-Based Systems?
Level II candidates need at least 2 years of documented water-based systems ITM experience, a work history description, and verified performance of key role-specific activities (performance measures). Level II technicians work under limited supervision on wet and dry systems, standpipes, fire pumps, private service mains, and tanks.
What topics make up most of the ITWBS Level II exam?
Intermediate ITM tasks for dry, wet, and standpipe systems plus deficiency classification are 30-40% of the exam, and ITM for water supplies (fire pumps, private fire service mains, water storage tanks) is another 25-35%. Internal obstruction investigation adds 10-20%, with safety and communication each 5-15%.
How much does the NICET ITWBS Level II exam cost and how long is certification valid?
The exam fee is $315 under NICET's standard CBT model. Certification is valid for 3 years and is renewed through Continuing Professional Development (CPD) points rather than retesting.
What is the difference between a deficiency and an impairment on this exam?
An impairment means the system or a portion of it is out of order and will not function in a fire event, such as a closed control valve, and triggers NFPA 25 Chapter 15 procedures. A critical deficiency materially affects performance without disabling the system, while a noncritical deficiency (like missing spare sprinklers) does not affect performance in a fire.
Which fire pump test values should I memorize for the exam?
Know the weekly 30-minute diesel and 10-minute electric churn runs (electric pumps monthly in many occupancies), the annual flow test at churn, 100%, and 150% of rated capacity, the 5% degradation limit against the acceptance curve, the 140% churn head limit from NFPA 20, and the two-thirds minimum diesel fuel level.
