The pool skimmer is a main entry point for your pool’s filtration system, and if the water level is too low or too high, the water cannot flow properly into the system’s pipes and filter equipment. Under normal operation, the pool water enters the filtration system through the skimmer, where it is transported through pipes or hoses into the filter and then returns back into the pool via the return jets. The skimmer also is responsible for trapping large pieces of debris, which are strained out by the skimmer’s basket.
If the water level is too low, no water at all flows into the skimmer and on through the filter system. Not only will there be no filtration occurring, but the filter equipment and pump motor may be damaged if it runs with no water flowing through it. If the water level is too high, on the other hand, the water flow through the pump system will not be as efficient.
The ideal water level is at the exact halfway point on the skimmer door, and when the level gets below the one-third point, more water should be added.
