I am plumbing/dry fitting a Herbie overflow. I have the two drain lines coming down from the bulkheads to the sump. One of the drain lines will be a straight shot into the sump. The other drain line will have two 45 slants. Should the main or the emergency drain be the straight shot?
Thanks,

I'd use the straight shot as the main. But, I'd make sure the other one will handle the needed return flow if the primary fails.

Keep it the way you have it. You're going to be throttling the main drain anyway so any (extremely slight) slowdown from the 45's will be irrelevant.

*Although I highly recommend using a gate valve, not a ball.
+1 to this

The adjustments I make to the gate valves on the two systems I maintain are around 1/32 of a turn of the gate valve wheel. Doing that with a ball valve would be frustrating to me.

Bonus points for buying a nice quality valve though :)
