I was talking with a friend yesterday and learned of a new to me pool closing method. Its easier than the normal drain the skimmer and return line method, but is it legit? Swears he has done it this way for years. I am here to ask what downside there is to this method.
The procedure is to run pump and add antifreeze directly to skimmers until it is visible coming thru return lines. Shut off pump. Plug return lines and install gizmos on skimmers. Place valve in winterize position. Your done.
This is in Cincinnati OH and inground pool.
Sounds too easy. What's the rest of the story?
