Okay, so I scanned all the previous discussion about converting a Hayward AquaTrol RJ to HP (inline configuration with flow switch) but nobody seems to be able to weigh in on it. Some threads say the RJ lacks the phone jack for the flow cell or that it has the jack but does not recognize the cell. Others say you can just buy the cell and plug it in and it will work. Has anyone tried this? It's been some years since many of these discussions... do we have a definitive answer yet?
