My UV filter is currently on 24/7 and acts like a little hot water tank on the cold water line when there is no water flow for a few hours. I was thinking about putting in a flow switch that will turn it on and off. Is there any reason not to?
I also have a Rainfresh automatic backflushing iron filter that measures water flow. I am trying to figure out if I can tap into the internal curcuitry to power a relay that would control the UV filter. Does anyone have any electrical specs/diagrams for the head unit in the pics attached? I see 2 pins in a yellow plug on the circuit board that I'm hoping might be an external dry contact for water flow.
