InterNACHI Pool & Spa Inspector study guide
InterNACHI Pool & Spa Inspector · Work through your exam, one topic at a time.
The InterNACHI Certified Pool and Spa Inspector designation is an association certification for InterNACHI members who want to add pool and spa systems to their inspection service offerings. According to InterNACHI's certification page, the path has three published steps: join InterNACHI as a member, complete InterNACHI's free online "How to Inspect Pools and Spas" course, and abide by the Continuing Education Policy for InterNACHI Certified Inspectors. Once those steps are complete, the Pool and Spa Inspector logo becomes available for use by current certified inspectors who have successfully finished the course. The certification is aimed at working home inspectors and inspection-business owners rather than at pool service technicians or water-chemistry operators, and it is a membership benefit rather than a state license. Note that InterNACHI's page does not publish exam length, question count, time limit, passing score, fee, retake rules, or validity period, so candidates should confirm those details directly with InterNACHI before scheduling. Because the course is the stated requirement, preparation centers on it. Topics on this exam: Pool and Spa Inspection (How to Inspect Pools and Spas course content).

01Pool and Spa Inspection
The Pool and Spa Inspection domain tests whether you can read a pool as one system: circulation, filtration, heating, water chemistry, electrical bonding, and the safety features that prevent drowning and entrapment. The How to Inspect Pools and Spas content supplies the vocabulary; the exam asks you to apply it to visible conditions and keep the report inside a non-invasive, visible-only inspection. Water travels skimmer and main drain, then pump, filter, heater, and returns. Turnover is the time needed to move the full volume once; residential pools are commonly designed around an 8-hour turnover, while many commercial codes call for 6 hours or less.

- Practice questionsA residential pool's water level is found to be exactly at the midpoint of the skimmer weir opening.
- FlashcardsTurnover time. Total pool volume in gallons divided by the system flow rate in gallons per minute gives minutes per turnover; residential pools are commonly designed for about six to eight hours.
- Cheat sheetWater turnover time equals total volume divided by flow rate; residential pools are commonly designed for roughly a 6-8 hour turnover, and a longer measured turnover signals undersized pump, clogged filter, or restricted suction lines.
- Key termsSkimmer. A device at the waterline that draws surface water and floating debris into a collection basket before the water reaches the pump.
- Study planMap the full inspection scope for pools and spas: define the boundary between what an inspector observes and reports versus what a licensed contractor repairs, and list the systems covered (basin and shell, circulation, filtration, heating, sanitizing, electrical, safety barriers, deck and equipment area).
- Common mistakesCandidates default to a visual 'fence present' check because that is what most pre-listing walkthroughs emphasize, and they underestimate how many barrier defects are dimensional or functional rather than visible.
