Why is it essential to maintain appropriate water levels in the pool?

Maintaining appropriate water levels in a pool is crucial primarily to prevent pump damage and ensure proper skimming action. When water levels are too low, the skimmer will not function effectively, potentially disrupting the filtration process and allowing debris to accumulate in the pool. Lower water levels can cause the pump to run dry, leading to overheating and serious damage. Furthermore, the hydraulic balance of the pool system relies on optimal water levels for sufficient water flow and circulation, which is critical for maintaining water quality and clarity. By keeping the water at the appropriate level, operators ensure that pumps and filtration systems operate efficiently, contributing to a clean and safe swimming environment. All in all, while other factors like visual appeal, temperature, and chemical usage are important, they secondary to the need for a functioning and protected pool system.
