I've seen this mentioned a couple times, what is a water level expansion module? Curious minds.....

I haven't decided which method I'm going to use yet.
The 2 options are positive pressure created by water displacement inside a 1/2" pvc pipe and resistance change on an eTape.
The one I have been using for the past month is eTape.
I'm going to switch to pressure next week or so to evaluate.
