How often should pools equipped with ORP controllers be tested?

Pools equipped with Oxidation-Reduction Potential (ORP) controllers should be tested before daily opening and once during operation to ensure that the chemical balance and sanitation levels are properly maintained throughout the day.

The reason for conducting these tests at the start of the day is to establish a baseline for water quality. This initial check guarantees that the sanitizer levels are adequate for safe swimming conditions. Furthermore, performing a subsequent test during operation allows operators to monitor any fluctuations in water quality that may arise due to volume of use, weather conditions, or other factors that could impact the sanitation process.

The frequency specified is aligned with best practices in pool management to safeguard public health while ensuring regulatory compliance. Maintaining proper water chemistry not only enhances swimmer safety but also prolongs the life of the pool equipment and infrastructure.
