Pool Return Lines
In the illustration below, you can see how typical pool return lines deposit heated, filtered, purified water near the top of the waterline—and typically only at three to four locations.
Typical pool circulation and dead zone consequences
Have you ever swam in a pool and suddenly hit a stretch of cold, dense, seemingly “heavy” water? If so, then you have experienced a dead zone.
Even a pool with the best pump is vulnerable to a dead zone, a mass of slow-moving “sluggish” water that inhibits optimal heating, filtration, and purification.
Because a pump can circulate “return” water through only three to four return lines in a typical pool, these patches of “zombie water” form. And when they do, it means bad news for your pool.

As a result, the odds for rapid, thorough dispersion are severely limited: The freshly treated water tends to remain near the surface, from where it slowly and incompletely disperses into other areas. By the time it does, the water is no longer as clean, warm, or pure!
Maintaining excellent water quality requires proper circulation, effective filtration, and balanced water chemistry working together.
Water quality is supported by:
When each of these systems works together, your swimming pool stays cleaner, clearer, and more enjoyable while helping protect the pool’s finish and equipment for years to come.
