Need Plumbing Feedback

[zenom]

I am working on my herbie drain for the new 165 gallon. Please let me know if you see any problems. Basically I have a quick disconnect on both emergency and normal drain. I have the gate valve right under the tank, then elbows going to the sump.

None of this is glued yet, I wanted to make sure it looked decent before I did so. I know I need to support the pvc somehow yet as well. Mostly wanted to make sure the gate valve placement etc looked ok.
