HI - first timer on this forum, in-ground gunite pool owner for 20+ years, Wakefield, MA - currently 40" of snow sitting on my cover...
For the past two years I'm noticing that my cover (and water) is being push WAY down by the weight of the snow that sits on my cover. Someone told me that it comes out the top of the pool but that's not the case in my situation as we got a light snow and the cover was sinking (pre-frozen in Dec). It's now about 3 feet below the level it was when I closed the pool (I don't drain any water when I close for the season).
Can it be getting pushed out thru my center drain in the deep end? I don't have any leaks during pool season and this has only started happening about two years ago. The water level is below the light so I don't think it could be that. Any insight would be helpful and very much appreciated.
