So I'm still not clear on how to use the water level... now that I think about it.

Tell me if I'm right here..

1. Make your water level.

2. Fill the bucket to an identifiable reference point, and create a siphon in your tubing.

3. Tack the tubing to a reference stick (we'll say a 2x4 for our example)

4. Set your 2x4 and bucket together in an area that you KNOW is level, mark reference points on tubing as to where "level" is.

5. place your bucket in the "control" area for your grading.

6. to check level, hold your 2x4 in an area and view the water level in the tubing relative to your reference mark. If the water is below your reference mark, keep digging. If the water is above your reference mark, you're too low and need to add dirt.

7. Repeat this process in enough places throughout your work site to be confident that the entire site is level.

Is this correct?
