Newbie here, and new pool owner, but I'm mechanically inclined and learn quickly. I'd like to close the pool myself and watched the pool company do it last year.
I can't figure out where to disconnect on the intake end to blow out the intake lines. I have two intake lines, pool and spa, connected rigidly to a selector valve and then connected rigidly to the pump. Can I disconnect further up between the pump and the filter and then blow air backwards (in the opposite direction in which it pumps water) through the pump and out the intake lines? Pictures attached.
Also, I have a 6.5 peak HP Shop Vac with a 2" blower port - will this develop enough pressure & volume to blow out the lines? I'll have to improvise to adapt the Shop Vac port to the pool PVC - so will the adapter need to be air-tight, or just a friction-fit adapter from the home store is good enough? My pump is about 6' higher in elevation from the pool. Thanks!
