Leo, thanks for the information. I think I understand what you are describing, but would like to see a picture if you do not mind. Here is a picture of the outer pipe, drilled and painted. I need to finish installing the grade316 Stainless hardware and put it in place. The vertical line of bolts are on 1" centers with the highest being at full pool level, that way I can easily tell my water level up to a 20" drop.
Stand pipe.
