As seen here, I need to get the liner out of my not-yet-completed pool. There is 3-4" of water in the liner right now. We tried to use a ShopVac, but it didn't have the oompf to pull water the five or so feet to the tank. My wife found this pump, which others have used to drain pools. Is it safe? Do I need to put anything under it to protect the liner?
Thanks in advance for your help.
