WHEN THE COVER WAS REMOVED FOR THE SPRING THE WATER LEVEL WAS LOW. WHAT COULD BE THE CAUSE??
-Before jumping to conclusions that the pool has a leak there are a few other things to take a look at. Check the cover for holes, even the smallest hole will allow the water to perk up from underneath. If a cover pump is used to remove rain water the pump will also be removing the pool water as well. If there is no hole in the cover, a lot of water displacement can happen. This occurs when rain water or snow weight becomes so great that it is pushing down on the cover, which then pushes the water from underneath up and out of the pool. This usually happens with big snow storms or if a cover pump is not used.

This happens when debris or organic material that gets passed through the skimmer and pump baskets and gets lodged in the impellar.
