I have read each of the other threads completely now. I'm a plumber by trade so p-traps I can understand. Do I need loops going down and coming back up or just on the way back up?
I'm think maybe just one run of 1/4 down the bore hole then, with the cap tube at the top. I'm sure this time of year the water table is at maybe 6 feet down. Should I not fill the bore hole? If water is best then filling with sand will only make it worse? I'm sure some dirt will fall in over time though.
I made a sketch up of what I am thinking. Any thing I'm totally forgetting?
