Depends if you want drain dry or wet. Lowered mine slightly from this picture to have drain a little wet. No teeth on the overflow but 2 high of the egg-crating. Top of emer standpipe is about even with water level of display.

For main was running without standpipe and didn't effect level in overflow (controlled by gate valve). Have standpipe now only to lessen the amount of water draining back to sump.

Hey thanks guys. When you say loud is that in the actual display or in the sump? I'm just curious as it doesn't matter if it's the sump as that's in my basement.

My herbie drain is silent it actually requires tweaking the odd time or after water changes I find, I hear basically nothing in the sump see either.
