Herbie Drain

[Parker]

On my set-up I don't run a riser on my primary and my emergency has a riser pretty close to 30" tall.

With the two pipes how far below the slots on the corner overflow does the main drain need to be ? An should the emergency drain be a 1/4", 1/2" , 3/4" , or 1" above the main drains height ? Can take pictures of my corner overflow if that helps too.
