My apologies for posting here, but I'm getting quite a bit frustrated with the line clearing process. Hopefully the attached picture will suffice in helping those visualize what I'm trying to describe. I consulted with my pool company, pool store, and youtube and I'm pretty darn confused.
I SLAM'ed the pool, dropped the water line four inches below skimmer and attached gizmo extensions to both skimmer boxes. I kept my pump on "filter" mode, leaving it off of course. I attempted to blow the shallow end skimmer returns by shutting of my main drain intake and deep end return. This produced some water flow. However, I didnt have any return plugs, so ran to the pool store to buy them (5 minutes). While I was gone, I left the filter on waste, to drop my water level an additional inch. When I returned, the filter was "filter" and not "waste". Now when I attempt to do any clearing, I'm getting very little water blowing out the returns.
As for the main drain, I have no idea how to blow that out. I closed my skimmer intake and deep end return while blowing air through one of the shallow end returns thinking this might funnel its way through the system and out the main drain... no dice. This is probably an incorrect procedure to begin with. For now I covered with a leaf net and thought I'd look here for advice before calling in a pro.
Any assistance is appreciated.
