The lines are different length for sure, but I was surprised to find the water depth to be consistantly about 14'. From the pictures of the orginal dig I was hoping for a deeper hole at the far end. Muskrats dug into the bank about 5 years after the pond was built plus normal sluffing of the banks filled it in pretty well.
I'm not sure how to run two seperate lines without having them twist. The windmill head could rotate more than 360 deg since there are no stops.
I figure the airflow is bound to change with the weather, but with no power to the pond and no desire to install a solar system at this time (about the price of a pump and dredge)this will have to suffice.
At least with the valves I could possibly shut one diffuser off in the winter. We have never had a fish kill, so I will probably just disconnect the air line since we like to skate.
I'll put pictures on too if I can figure out how to!
