How to stop air entering Pentair Pool Products D.E. Cartridge Style Filter Quad D.E. Swimming Pool Filter?

  Jessica BradleyJul 26, 2025
  To address air entering the Pentair Pool Products Swimming Pool Filter, first, correct any conditions in your filtration system that allow air to enter. If the skimmer is starving for water due to a low water level in the pool or spa while the pump is running, add water. Air bubbles or low water level in the pump hair and lint pot may be caused by low water level, a clogged skimmer basket, a split suction cleaner hose, a leak in the pump hair and lint pot lid, or a leak in the pump suction line. Address these issues accordingly. If air is discharged from the High Flow™ manual air relief valve on top of the filter when the valve is opened with the pump running, refer to the initial steps.

  Short filter runs in your Pentair Pool Products Swimming Pool Filter are normal until the water initially put into the pool has been completely filtered. If the issue persists, clean the filter elements, as plaster dust can cause short filter runs requiring frequent cleaning. Overcharging with D.E. can also cause this issue.

  If the pressure drops on the gauge of your Pentair Pool Products Swimming Pool Filter, shut off power to the pump and turn the motor shaft with your fingers. If it turns freely, disassemble the pump and check the impeller for clogs. If the impeller is not frozen or clogged, there may be an obstruction in the line between the pool and the pump.
