Maybe I'm just paranoid AND forgetful - I remember cleaning out my skimmer sock recently and thought I put it back on the skimmer basket, but maybe I didn't? Anyway, this morning I see no skimmer sock on the basket and (perhaps because I have fresh memories of a giant soap-scum-and-hair clog that hubby cleared from the kids' bathroom sink) now I have this fear of a wad of skimmer sock somewhere between the skimmer and pump basket collecting all sorts of plant detritus behind it until the pump explodes from overexertion.
So - supposing the skimmer *did* ingest the sock - what would be some obvious signs (other than the sock making its way into the filter basket)? Is there any way to flush it out? I assume the "backflush" setting of the filter runs water to waste, not back to the pool.
