The treatment system of a pool is typically recommended to be installed in which of the following flow arrangements?

The recommended flow arrangement for a pool treatment system is vital for ensuring proper circulation, filtration, and sanitation of the water. The correct answer outlines the most effective configuration for this system, which allows for optimal performance and maintenance of water quality.

In this arrangement, the skimmer or gutter line serves as the initial point for water collection, capturing debris and contaminants from the surface of the pool. Following this, the main drain line contributes to overall water circulation, ensuring that all areas of the pool are effectively serviced. The inclusion of adjustment valves allows for control of water flow and distribution throughout the system, which is essential for maintaining balanced water chemistry and efficient operation of the treatment components.

The sequence continues with a hair strainer, which prevents larger debris from entering the pump and causing clogs. This is crucial for protecting subsequent components. The placement of the disinfectant feeder after the pump and filter is significant—it ensures that sanitized water is returned to the pool efficiently after having passed through the filtering process, crucial for proper disinfection and maintaining water clarity.

The introduction of a filter aid pump and filters aids in enhancing the filtration process by allowing for additional treatment before returning water to the pool. Furthermore, the inclusion of pH feeders allows for fine-tuning of water chemistry
