Decided to try it, and ordered a UP2/E.... just delivered today.
Very compact, tank testing seems to work
great. Might get another I like it so much (so far). Run them in parallel for redundancy and also have the ability to drain the water tanks
2x the speed.
The two led's (one blue and one multi colored) will tell you a multitude of things about the pump
- solid colors, flashing, etc.... Very cool stuff.
