Hi all. I am using an RO line with a solenoid and water level sensor as my ATO and have an aqualife smart buddie with my RODI setup. I've noticed that when the solenoid shuts off the line, the smart buddie will occasionally click (probably every 30 seconds or so) and a small trickle of water will come out of the waste line. I thought the smart buddie was supposed to completely stop the water flow coming from the RODI but is this normal?
