I woke up this morning thinking I was going to have an overflowing pool given the heavy rain we got last night. Instead I lost several inches of water. Water was barely getting into the skimmer. Now yesterday we had a pool party and I turned on the waterfall, and at the end of the night when the rain started coming down, I neglected to shut off the waterfall. Now my first thought this morning was that there could be a leak in the piping feeding the falls, which can be the case since I barely ever turn this thing on. However could it be something else? We had some pretty heavy winds last night also. Thoughts?
