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?
