The swimming pool eyeball inlet, also referred to as a return jet, is a key component in a pool’s circulation system, designed to return clean, filtered water from the filtration system back into the swimming pool. Named for its ball-shaped, adjustable nozzle, the eyeball inlet allows for directional flow control, making it an essential tool for maintaining balanced water circulation and optimal chemical distribution.
Typically installed in the pool wall just below the waterline, the eyeball inlet is engineered from durable, corrosion-resistant materials such as ABS plastic or PVC, making it suitable for long-term exposure to pool chemicals, UV rays, and varying water temperatures. The nozzle can be manually adjusted to direct the flow of returning water, helping to improve water movement throughout the pool, reduce dead spots where algae can grow, and enhance surface skimming.
Eyeball inlets play a crucial role in keeping the pool water clean and evenly heated, especially when used in conjunction with the pool’s main drain, skimmers, and heating systems. By directing water flow strategically, they also assist in more effective cleaning during vacuuming and ensure that sanitizing chemicals are evenly dispersed throughout the pool.
These fittings come in a variety of sizes, styles, and flow ratings to match different plumbing systems and pool designs. Some models include interchangeable eyeball nozzles or flow restrictors to adjust the pressure and direction of water return even further. Installation is typically straightforward, with the inlet threaded or glued into a return line fitting in the pool wall.
Ideal for residential and commercial pools, spas, and water features, the eyeball inlet is a small yet highly functional element that enhances the efficiency, cleanliness, and overall performance of the swimming pool system.
