I have edge pump for vanishing edge that has electronic levolor autofill. I'm still trying to figure out how this autofill works but what do you recommend on how long should I run edge pump for? IS the longer I run it, the more water adds with auto fill? I turned it off after 15-20 min of running the pump and I can see the levolor power/sensor/fill are still one for sometime after that, so seems like it doesn't matter how long edge pump runs ?
