This component is a plumbing connection designed for swimming pool circulation systems. It facilitates the return of filtered water back into the pool after it has passed through the filtration and heating systems. A common configuration features a two-inch diameter, enabling a standardized flow rate suitable for many residential pools. It is often constructed from durable PVC plastic to withstand the chemical environment of pool water.
The proper functioning of this fitting is crucial for maintaining water clarity and even distribution of chemicals throughout the pool. Its design allows for adjustable flow direction, aiding in the prevention of stagnant areas and promoting efficient sanitation. Historically, such fittings have evolved from simpler designs to incorporate features that enhance water circulation and minimize pressure loss, contributing to overall energy efficiency of the pool system.
