It has rained several inches over the past few days so we desperately need to rain water out of the pool. When we had a crack fixed by a fiberglass pool professional several years ago, I was told to never drain the pool if there is ground water present because it can cause the fiberglass to crack or even pop out of the ground, even if the pool is full of water. Unfortunately, I don't have a sump pit to drain water out from around the pool. Could I safely drain it if I used a sump pump and directed the water far away from the pool? Or do I need to wait 24 hours before draining it so the ground can dry out some? After seeing how much it costs to fix a crack in a fiberglass pool, I'm always hesitant to drain water out after heavy rains.
