I think I devised a pretty slick way to close the pool my self. I removed the drain plug from the pump after lowering the pool level to just below the skimmers and replaced the 1/4 plug with a quick fit 1/4 inch air compressor plug. I plugged in my pancake compressor and hooked it up to the quick release. I pressurized the system to about 10 psi and blew out the two skimmers, the main drain and the return lines. I went around twice to make sure the lines were dry. Worked great!. I have enjoyed this forum and hope this helps someone else.
