Hello All, closing my pool for first time and could use some help. I live on the east coast and have drained water below skimmer and returns(1 skimmer 2 returns) trying to blow lines out and having a problem.
Im using a shop vac and when I blow into skimmer or filter pump no air blowing thru returns, blowing into filter pump I get air out of skimmer and vice versa but can't get air out of returns.
I capped the returns by the stair spas and still no luck, I also have a waterfall and slide that I shut but same results.
im new at this so any help would be greatly appreciated.
