CPI CPI Spa & Hot Tub Specific Requirements 2 — Questions and Answers
Question 1: What is the typical minimum turnover rate requirement for a public spa?
- Every 8 hours
- Every 4 hours
- Every 30 minutes (Correct answer)
- Every 2 hours
Correct answer: Every 30 minutes
Most state codes require spa water to turn over completely every 30 minutes due to the high bather-to-water-volume ratio.
Question 2: What suction fitting requirement specifically applies to spas to prevent hair entrapment?
- Suction fittings must be chrome-plated
- Suction outlets must meet ANSI/APSP-16 entrapment protection standards (Correct answer)
- Suction fittings must be located on the spa floor only
- Suction outlets must be at least 6 inches in diameter
Correct answer: Suction outlets must meet ANSI/APSP-16 entrapment protection standards
All spa suction outlets must comply with ANSI/APSP-16 to provide certified entrapment protection for hair and body.
Question 3: What minimum bather load restriction is typically posted for public spas?
- There is no occupancy limit for spas
- Occupancy is set at 1 bather per 10 square feet of water surface area
- One person per jet
- Occupancy is set based on seating positions or square footage per code (Correct answer)
Correct answer: Occupancy is set based on seating positions or square footage per code
Occupancy limits for public spas are set by state/local code, typically based on available seating positions or a defined square footage formula.
Question 4: During a CPI inspection, what should an inspector check regarding a spa's skimmer?
- Color and aesthetics of the skimmer lid
- Presence, condition, and correct flow rate of the skimmer (Correct answer)
- Whether the skimmer is made of PVC or ABS
- The brand marking on the skimmer basket
Correct answer: Presence, condition, and correct flow rate of the skimmer
The inspector must verify the skimmer is present, undamaged, and that flow through it falls within the manufacturer's rated range.
Question 5: What is the role of a thermal cover (hard cover) on a spa when it is not in use?
- Purely decorative
- Prevents heat loss, evaporation, and unauthorized access (Correct answer)
- Increases water temperature above 104°F
- Substitutes for a fence barrier
Correct answer: Prevents heat loss, evaporation, and unauthorized access
A thermal hard cover conserves heat, reduces chemical evaporation, and helps restrict unsupervised access when the spa is closed.
Question 6: What is the minimum required free chlorine level for a public spa in most US jurisdictions?
- 0.5–1.0 ppm
- 1.0–3.0 ppm
- 3.0–5.0 ppm (Correct answer)
- 5.0–10.0 ppm
Correct answer: 3.0–5.0 ppm
Most US health codes require public spa free chlorine to be maintained between 3.0 and 5.0 ppm due to elevated temperatures reducing sanitizer efficacy.
