we have problems with ground water around our IG pool in spring and after heavy rains in the summer. For years we have used a siphon pump placed behind the liner to remove it when necessary. Over the past couple of years, we've noticed that some new pool installs have a dry well set up close to the perimeter of the pool, and its covered over with a cover similar to the skimmer cover. We were wondering if we could dig a hole just outside of the cement apron around our pool, place in a large plastic tube liner, fill part way with stone and use this to drain ground water away from behind our pool. Has anyone done this? I think it would be about 3-4 feet away from the edge of the pool. Thanks in advance for any thoughts or input!
