I'm a new pool owner, and I came home to something quite interesting this morning. The pool water level was about 3 inches lower than it was yesterday. I set the timer and was not home when the pump turned on last night and this morning. Now when the pump primes up, water seems to be pumped right out of the drain. Any ideas on how to fix this? At first I thought it was a broken pipe problem, until I ran the pump a few minutes and water started flowing from the drain. I haven't moved any of the levers. I'm attaching pics of my setup, and the drain where the water was flowing out. Any advice would be greatly appreciated!
