摘要： An improved seal for insertion into a skimmer of a swimming pool that attaches to an intake pipe of the pool filtration equipment and extends into the walled region of the skimmer to provide a compressible body absorbing the expansion of ice during freeze-up of the pool. The seal comprises an air valve for introducing air via an inner shaft into the intake pipe line to clear out water. The seal obviates having to lower the pool water level.
