This morning the electrician comes out to temporarily power up the pump to get the water moving. I start to walk around and check the returns to see how the flow was moving. I start to think that this pool has five returns and and I can only find four??? The electrician says he doesn't know. So I begin to feel around and sure enough, there is a return that wasn't cut out through the liner! The pump ran for 10-15 minutes putting water between the liner and steel wall/concrete. The PB says he will be out today. What should be done to get this fixed? Is this amount of water enough to be worried about?
