I don't have a main drain in the pool and 1 skimmer w/2 returns so I believe this makes things a lil easier for me.Thanks for the assist.

The Cyclone is a great piece of machinery. Given your pool, you probably could have accomplished this by using the blow out plugs with the Schrader valves. Lowering water below the skimmers, using an air compressor, along with a shop vac for the skimmer, then clearing the return lines one at a time. You could have even isolated one return, or burped the system as well.
