Hi - just recently installed an osmolator. Mounted it in my sump. The water level dropped sufficiently to activate it today. It ran fine and cut off at the right level. I left the room and came back an hour or so later and there was a constant stream coming from the supply line from my reservoir. The controller showed a green light -- the pump was not active and the flow was not as intense as with the pump on. None-the-less it had raised the sump level by an inch before I caught it. Any suggestions? Jay.
