I have a Pentair Intellichlor that I think might have a bad flow switch. When I run the pump normally the Flow light is red. If I turn a manual valve coming from the filter about a quarter of the way closed it raises the filter pressure from 10 to 14 and then the flow light on the Intellichlor turn from red to green. My guess is that the switch works with the higher pressure. How much pressure is needed for the switch? Is the switch bad?
Thank You,
