Sorry Lastlight not quite following you here. When I was running it to test it, there was no noise, great siphon. The 1" drain has about 2" of 1 1/2" pipe sticking up and the 1/2 emerg rises to about halfway up the overflow teeth. there was no vortex at all, ran great like that for 3 days. Only problem was I used a ball valve instead of a gate on the drain which I will change. Problem came when I blocked main and the emergency line seemed a little small.
So are you saying that if I increase the secondary emerg drain size it might cause the siphon to not work the same ?? Presently the two lines are only 1 5/8 apart. A picture would help and I can't post one till tomorrow to clarify this.

It's an internal ..Never thought about this possiblity, definately a workable solution if the other doesn't
Thanks and sorry for needing the clarifacation.
