20'x40' inground vinyl, built in fall 2011.
I wasn't planning on opening the pool for another few weeks but I wanted to take a look under the cover today just to see if the water was still clear. Last year (our first year) it was green but we put a much improved cover on last fall. This is the mess I found. The water level is about 3 foot low. The original shape of the pool seems to be there under the liner bulges.
My gut feeling is that its my fault for leaving a sump pump in the pool to maintain the level over the winter and its has siphoned off after shutting down the pump. I'm just guessing at this point but it seems like an odd height for a hole.
I'm in shock right now, what do I do?
Will the liner go back to correct shape when I refill?
Is this going to cost me a fortune and is my wife going to kill me?
