Alan M. - thank you for your answer.
You say "the outlet pipe should be 1/2the diameter(3" in your case) up from the baffle."
Seeing the walls will be 12" does that mean 3" from the bottom or 3" from the top? Sorry to be so thick......
Thank you.
Howard
3" from bottom, so the tube will extend down approx. 9" from the top.
Looking forward to starting this one.
I'll keep you posted.
