Jgray152;1862019; said:I decided to do some work on the design of the cover. After many thoughts and designs, I have sketched this out.
The way it works is as the water level rises and the air gets forced or pulle dout through the purge tube, the air will start to get forced to the sides of the cover. Especially after the water level get to the point of touching the cover, all the air will be forced to the sides and pushed around to the purge tube.
