I own an 18X36 IG pool and live in Massachusetts. For as long as I've owned the house, I've used the Winter Safety Cover that the prior owners installed. It is the green mesh type that attaches through spring straps to large metal bolts/screws drilled into the concrete deck.
This fall I am having the concrete deck removed and will take the fall and spring to install pavers myself. Because of that the bolts that the winter cover attaches to hold down won't be in the ground before the winter starts.
So...Is it perfectly fine not to have the safety cover on the pool over the winter? I've got a pool fence and don't have children, so I don't think there is much safety risk. Are there other reasons (other than keeping leaves out during the fall) that make a winter safety cover something I really want attached all winter?
