Unless I am not understanding the setup correctly.

Ohhh dear. I think you're right.

Wow, how did I miss that.

Um .. yeah Jason, I'm sorry but Dale's right. I clearly didn't have enough coooffffeeee after 4 hours of sleep last night.

A T won't work at all. All the water will need to come all the way up, and then back down again in order for a hole to service as a siphon break. As long as you have this looped up over the top of the desired water surface, I think it will work (it will be the same as if it looped over the top of the tank wall).

I think it's that (and still have to figure out a way to deal with the water coming out the hole when the pump is turned on), or, use the drilled holes for a closed loop.

Man alive ... do I ever feel dumb. Sorry man.
