Not really sure I needed to send a picture, but since I'm new and still learning, valves is not something I've spent much time on. Just perfecting the water chemistry for now. Anyway, I had a new SWG installed a few weeks ago and I'm sure the guy was trying to be helpful, but I just want to understand why he did it and if he's correct for adjusting. He said something like I don't need that much water going to the heater? At least, that's what I think he said, hence, why I'm sending the picture When he made the adjustment, the PSI on my filter gauge went from 12 (that's the number when cleaned or new) down to 8. Can you guys explain why he did that? Would that affect the amount of chlorine the SWG produces (less, more or doesn't matter)? Should I change it back? I think the valve was in the middle before.
Thanks for your help.
