My pool is being closed today. I have a mesh safety cover. Usually I have to drain the pool a couple times over the winter because of snow and rain. I was thinking instead of going out in the cold winter I would just drain the pool down to around the return jets now. The pool company told not to do that because the water helps support the cover over the winter when it accumulates snow. Is this correct? I hear people draining their pools at closing all the time.
