Certified Pool Operator Practice Test 2025 – All-in-One Guide for Exam Success!

Filtration and recirculation pumps should operate for 12 hours continuously for public spas and therapy pools because this ensures proper filtration and circulation of the water to maintain optimal water quality and safety for bathers. Pool and spa operators should also monitor and adjust this time as needed depending on the size and usage of the facility. The other options (B, C, D) are incorrect because they either exceed the recommended operating time (B 18 hours) or are insufficient to maintain proper water filtration (C: 24 hours, D: 8 hours).
