And that would describe my situation: 35' from the pump to the closest point on the pool (in my case, the skimmer). Then another 8' horizontal to the drain.

That's why I go to the trouble at all to try to blow it out, to get water out of that horizontal run. I'd like to know the density of this RV antifreeze I hear about. If poured into water, will it sink or float? Or just mix?

Maybe I can get Letterman to try this for me??
