I used to use a shop vac exhaust and I would jam it into the stanchion for the skimmer and the returns. That was a pain because i needed 2 people, one to hold the blower and one to see when the pipe was clear (no line of sight from the filter). This year I hooked up an auto tire compressor to the pump basket and blew the lines, I just don't trust that I blew the line completely. I was looking at the cyclone blower but the price is a little up there at $350. What can you recommend? Thanks.
