Durso Style Drain Whistling

[Wayne]

I will drill another hole, I already have a 1/4" hole there and it has been like this without problem for months now. I can't really see why my addition to the end of the pipe would change anything. I may also plug the open to air end and see if that helps.

Anyone know more about putting T's on the end. I heard it would help and I had nothing to do Sunday... Idle hands...
