So we have the pool store open and close our pool. They came out today to start draining the cover and put the hose in. around 12:00 I noticed the cover was mostly drained and it looks like there is barely any water in the pool. I checked the picture from October when we closed and the water level was significantly higher, plus the hose has been in since 8am. Does anyone know what this could be? Could they have messed up closing it? They are coming to open tomorrow and they said the openers will let them know if there is an issue. any idea what I might need to expect?
