Getting ready to install this tonight Edge 40). I see the recommendations to have a timer and I understand the reasoning. Do flow switches really fail closed like that? As in, they fail and still send signal that there's flow when there's not? Only reason I ask is I have a VSP Pentair pump but no automation, just it's built in programming (runs about 12 hours a day). I do have a timer already installed from my prior non-vsp pump, right now it's just 24 hour on because I use the Pentair programming. I could use that existing timer to wire the outlet for the SWG and then run a new run to the pump (just more of a PITA because I have to open the switch housing for the pump). Even the timer isn't perfect, though. If my pump failed stopping water flow and the flow switch was bad and the timer was still energized it could still explode?
Side question, what RPM is typically required to get enough flow to activate the SWG?
