The emergency is already on a 90° angle, the drain is going straight out the bottom with a standpipe and the emergency drain is drilled into the side about 1.5" above the top of the standpipe. It's just a bulkhead in the side of the overflow. I have the drain standpipe not far from the bottom of the weir teeth to keep the overflow quiet. It's easy enough to set it up so I have a small trickle down the emergency drain. I would have to extend the plumbing because I left it short of the sump water level on purpose so I could hear it if water was ever going through it. If I extend the emergency drain below the water level of the sump, is the water going to back up the drain or will it actually work its way into the sump? I guess it would be fine as long as it's not straight up and down.
