The skimmer weir is located at the entrance to the filter compartment, and is designed to allow water to enter the filter area. Additionally, the weir is designed to remove or skim any floating debris from the surface of the water.
When the filter area requires more water (jet pump activation), the weir will move down to allow more water to enter. Conversely, when the filter area requires less water (jet pump is deactivated), the weir will move up to decrease the amount of water entering the filter area.
The skimmer weir consists of a blade assembly, weir frame, pivot button, pivot brace, and a key.
If a weir blade becomes stuck in the up position, the jet pump can surge due to lack of water.
If a weir blade becomes stuck in the down position, the skimming action used to remove debris will be eliminated.
