Hayward Paramount Paralevel 004760290201 White Paralevel Complete Water Leveler. Paralevel is continually working behind the scenes to ensure that your pool or spa is at its ideal level. You can rest easy knowing that your pool’s water level is being monitored and adjusted automatically. If you ever need to make a manual adjustment Paralevel’s “Posi-click” adjustment makes it easy. One full turn equals ¼” (6 mm) of water level adjustment. Unlike other water levelers Paralevel offers “Smart Sensing”, which means it will ignore water sloshing in the pool as it only senses the pools true level.
