So i had a company close my pool. I went out there after a week and the skimmer gizmo plastic thing was floating in the skimmer. It has rained since then and the skimmer is full of water now. I called the well know company and he said just screw the gizmo back in. I said but its full of water now. He says" i put antifreeze in the line and it will be ok." Is this ok? Should i vacuum the skimmer line out and put more antifreeze back in then put the skimmer gizmo back in? Advice please, im a new pool owner
