First of all I did read the instructions in the closing section. However, as a newbie some of the steps are not clear to me. The pool company usually closes the pool using a compressor and that is not covered in the closing section (sad to say I don't even know where to plug the compressor in). Also not covered is how to do it without having to lower the water level below the skimmers. My main concern is blowing out the lines and making sure the heater gets done as well. I've attached some pictures of my filter, SWG and heater, hopefully someone can point me in the right direction. Thanks.
