I just got the new style 300 deluxe internal, it has the long cone neck like the SM. I am very impressed with the build quality and how quiet it is. Here's the problem. I have the telescopic adjustment as high as it will go and I have the wedge pipe all the way in the closed position and water still comes out of the exit, I can't get the water level up high enough in the skimmer. it is sitting in 9" of water, does anybody have any suggestions and with the wedge pipe turned all the way closed shouldn't it stop the water from exiting coompletely? Thanks
