I'm pondering attempting to close the pool myself for the first time this year. Been reading in this forum and watching lots of youtube videos. I have A LOT of questions. But, I'll start with this. Below is my setup. Seems relatively normal. Intakes are on the right of the picture, returns are on the left. My first major question... None of the PVC valves seem to disconnect easily. So, if I have the Cyclone and hose attachment, where would I use blow the out return lines from?
