Recently purchased a Summer Escapes 16' x 48" ProSeries Metal-Frame Above-Ground Pool. 3 Days to level the gound, set up the pool and all sides are level. Pool is now filled but water is off about 1" on the side directly accross from the skimmer. Plugged pump in and this is where the problem starts...the Skimmer/Filer Pump System is mounted to the side of the pool through the precut opening and the skimmer weir/door is not opening and closing properly so the pump is sucking in more air than water which you can see as it comes through the return. If you slowely open the weir/door and allow the water to fill in everything works perfect. I feel this may be caused by the other side of the pool being off level by an 1", could this be the problem, or could maybe the gasket and frame been tighten down too much? Any easy fixes other than draining 18K + gallons of water to re-level?
