I had a service close my pool this past fall. I am in NJ and we had about a foot of snow last week. After an all-day rain storm yesterday, the snow has washed away. Today I noticed one of the skimmer covers raised up. I know when the pool was closed, the skimmers were sealed up and an empty antifreeze container was placed on top.
Today I slid the raised skimmer cover back from the mesh winter cover and I can see the skimmer has water in it and the empty antifreeze container has floated to the top, therefore pushing the skimmer cover up.
I assume the water got into the skimmer from the rising level of pool water (water was dropped below skimmer in the Fall) or water that found its way in through the finger hole in the cover.
Is this normal? If not, is there something I should do to fix this situation? I'm concerned about the water freezing and cracking the skimmer.
