I found a few articles in regards to this, but I'm still confused on what to get.
I tried 6.5hp shop vac and it'd do skimmers just fine, but for whatever reason it would not do returns or even vacuum line. I can't figure out why, as vacuum line works just fine when used, and it doesn't go through filter\heater. Main drain - forget it.
I know yellow and orange Mighty Vac do the job, but spending over $300 for something I'd use only once a year seems like an overkill.
As for compressors, can someone recommend the specs on what's needed?
Someone (I believe on this site) mentioned that 2 scfm is not good enough. And then pancake ones are not good enough. Then 2HP may not be enough. I don't know anything about air compressors, so need help
What is good enough and safe to use? how much psi is too much and can damage lines?
P.S. Would something like this be enough to blow all lines?

Or do I need something like this (my neighbor will have this one on upcoming garage sale for about $150. just found out )?
