Pool skimmers are designed to draw water from the surface and suck it through the pool’s filtration system. About the top 1/8 inch of water is drawn into the skimmer helping remove the contaminants and debris such as sunscreen, hair and leaves from the pool before they sink to the bottom.

What are the 2 holes in skimmer?

The second hole in the skimmer is connected to a pipe called an equalizer. This pipe goes down approximately two feet and through the concrete wall of the pool. It prevents the pump from taking in air if the pool’s water level dips below the skimmer opening.

Can you run pool pump if water is above skimmer?

If the water level is too high the debris floating next to the opening may pass by without being pulled into the skimmer. However if the water level is too low it may cause the skimmer to suck air into the system. If this happens you may run the risk of burning up your pool pumps motor.
