That makes perfect sense. I wouldn't have thought of that prior to my install. Thanks!

I think I get it. So when using a Wye fitting it's best to have the Wye angled off on the same plane as the main trunk as opposed to pointing straight down?

Yes...it helps prevent a lot of material that "passes by" that drop from falling down into the drop.
