Hi all, glad to be part of your forum (new member). I have an inground pool and I'm getting ready to open it. There was a tremendous amount of water on the cover (like thousands of gallons); we had a very hard winter. I've been pumping water off of it all day and have made a big dent in it, but now it seems like the water level underneath the cover is getting low too, like I'm draining the whole pool in the process of draining the cover. Am I doing something wrong? Should I stop and call a professional?
