Hello - not too far away from closing the pool for the summer and was just trying to make sure I had everything I need. I have an auto cover so will not be lowering the water level at all. I see a lot of people that mention using the Air Supply Cyclone blower (about $332 on Amazon right now). Is this the best option for blowing out the lines? I have a shop vac but not sure if it will be powerful enough? Any other options? Thanks for the help.
