What is the purpose of hair strainers in a pool?

Hair strainers serve a specific function in a pool's filtration system by catching debris, such as hair, leaves, and other small particles, before they enter the main filtration system. This is crucial in maintaining the cleanliness of the water and preventing clogs in the pump and filter systems, which can lead to more significant issues if not addressed. By effectively trapping larger debris, hair strainers help ensure that the water can circulate properly and that the filtration system can operate efficiently. This, in turn, contributes to a more pleasant swimming environment by reducing the buildup of contaminants and promoting clearer water.
