I tried to heat our pool for the first time a few days ago and probably messed everything up moving all of the valves. Prior to my blind manipulation of the valves the pump would turn on automatically from 9pm to 3am and I could hear the waterfall from the spa poor into the pool. Now, the waterfall does not turn on (don't even know how to turn it on) and I don't see any movement in the water (not even from the automatic cleaner my husband bought). I'm not sure how the valves work despite countless hours of reading blogs and watching youtube videos. Please help.
