I...... Eliminate the low spots and provide a continuous grade on the air lines. To quote 10X "These lines go up and over the bank out to the diffusers." Cut the lines thru the bank to keep the downward grade and eliminate the "traps" to fix the problem instead of continually fighting it year after year?
If I cut through the bank at the level that the line is, I will be in about 7-8 feet of water. I don't know of any way to cut through the bank with the lines and maintain the integrity of the bank while doing so. Maybe there is a technique for it but I can picture a damn breaking or a leak forming by running it through. Wouldn't that give the water a nice straight path to leak? They cut a "key" around the perimeter when they made the pond to eliminate any direct path for the water.
