Abstract
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.
Claims14
In a swimming pool having a skimmer including a walled region and an intake water line for connection to filtration equipment, a seal for protecting said skimmer and said water line from ice damage comprising:
- a hollow body having an outer wall of resilient material, said body extending from said intake water line to be compressibly disposed within said skimmer walled region upon formation of ice therearound;
- a first end of said body having valve means for introducing and maintaining air under pressure to said intake water line;
- said first end comprises means extending upward for providing a grip to screw said seal into said intake water line with said valve means positioned in the center of said grip providing means;
- a second end of said body having a cylindrical projection, said projection having means for securing said body to said intake water line;
- and
- means within said body extending from said first end to said second end for directing said air through said body.
