DC70,
Now I see what you were saying! Thank you for the drawing! As they say a picture is worth a thousand words. You wanted to reduce the amount of noise and thought you were going to need to move to the far end of the dam. However, after moving the 4” vent pipe a little over 3’ the noise was dampened (muffled) enough by the smaller 4” pipe. Btw your drawing is much neater than mine.
Thanks!

How do you manually prime the siphon if you wanted to do a drawdown?
