I have been using one on my elos MIDI for about a year now. I have it located in my RO/DI chamber in my elos sump that holds approx 4 gallons of water. It has been working great so far. When the water level gets below the tip of the stainless steel probe it will kick on the pump which is quite powerful. There is a manual button on the controller that you can push to manually activate the pump which if just pushed quickly seems to put out a minimum of a 1/4 cup. The tip of the probe has developed a little of a rust color on it but it is still working just fine. Spoke with Jesse at elos and the color may be coming from GFO.
