CPO Pool & Spa Equipment & Facilities Flashcards

What is the primary benefit of an automated chemical dosing system?

Answer: It dispenses sanitizers at a controlled, consistent rate to maintain proper chemical balance automatically

Automated chemical feeders maintain consistent sanitizer levels by dosing at controlled rates, reducing the risk of dangerous under- or over-dosing between manual checks.

What maintenance task should be performed on the pump strainer basket regularly?

Answer: Inspect and clean it to remove debris that could restrict flow and damage the pump

Regular strainer basket cleaning removes accumulated hair, leaves, and debris that would otherwise restrict pump flow, cause cavitation, or damage the impeller.

What is the purpose of a pool vacuum system?

Answer: To remove settled debris from pool floors and walls that filters and skimmers cannot capture

Pool vacuums — manual or automatic — remove debris that has settled on the pool floor and walls, which skimmers cannot reach and which would otherwise decompose and affect water quality.

What does a pressure gauge on the filter housing indicate when it reads higher than normal?

Answer: The filter media needs backwashing or cleaning due to accumulated debris

A rising pressure reading above the clean baseline indicates the filter media is loaded with debris and restricting flow, signaling the need for backwashing or cleaning.

What type of pool lighting is recommended for energy efficiency and longevity in modern facilities?

Answer: LED lighting for low energy consumption and long service life

LED pool lighting consumes significantly less energy than traditional options and lasts much longer, reducing both operating costs and the frequency of hazardous underwater lamp replacements.

What is the CPO-recommended pH range for pool water?

Answer: 7.2–7.8

The recommended pH range of 7.2–7.8 (ideal 7.4–7.6) balances chlorine effectiveness, swimmer comfort, and protection of pool surfaces and equipment from corrosion or scaling.
