Thanks.

The water line is adjustable using a valve on the full siphon drain line. Generally, the water line is ~ the horizontal center line of the elbow. The elbow will not be fully submerged usually. On 1.5" pipe, the bottom of the Tee is 2 3/8" below the elbow center line. The inlet to the elbow is a little less. You want the inlet of the elbow ~1" give or take off the floor of the external overflow, ideally. The above drawing has some "wiggle" room to adjust the Tee up and down, to dial things in.
