[Resolved] The 6mm tap valves To Parent Forum October 30, 2020 at 1:17 pm #652 fusiongrowerParticipant I couldn’t find anything in the instructions but how do you know if they are turned on? I have two one that goes just before the reservoir and another at the end of the line. Are they open when the arrows point forwards?
