I normally had someone come and close the pool, but am ready do it this year. And of course, with that come questions.
Our pool has the big gizmos thing for the skimmer and we plan to use that. The person whom closed for us in the past would always put the empty gallon jug of shock into the skimmer too, and I never understood why. Is that really necessary?
What is the best way to completely drain/empty the lines? How does one go about the bottom drain? Shall all the return valve be in closed position as well?
I am sure there will be other questions, but that's all for now. Thank you so much for the usual help.
