I have a 14K fiberglass pool and I need to blow out the lines including the 8' deep end main drain.

Does anyone use an air compressor to blow out the lines of their IG pool?
If so what pressure is the max? Is there enough volume?
If not what kind of commercial blower is best?

I have a nice air compressor but I understand volume is needed not so much pressure. I nice electric leaf blower does nothing for my returns, let alone the deep end.

thanks Kevin
