My pool is due to get plastered Sunday. It was pumped out and cleaned last week. in advance of the tropical storm moving up the east coast, I opened one of my drain plugs in the deep end... at the time a little water flowed in. I knew the ground water table was 6" or so above the deep end floor. I left the plug open to see how much change I got during the rain. I now have about 2 to 2.5 feet of water in the deep end. The plug is still open, so I am guessing that this reflects the true ground water level. The deep end is about 20 x 16 by 7.5 deep at the deep point. There is another 30 ft to the shallow end wall.
They are still scheduled to plaster tomorrow. I know there are calculations I can do to determine the approximate height of ground water needed to exert greater force than the weight of the deep end and cause a problem... but I am just looking for some general info about whether this is anywhere near enough to cause an issue... and how PBs plaster a new pool where the water table is up a bit... I have 4 drain pots in the deep end... I am guessing they will run a pump or two during the plastering? My concern is if that does not keep up with the inflow, they will just plug it and plaster.
