I did a dumb thing this morning. I backwashed my filter, then set to rinse(which I usually do for 10 seconds). I got called away while rinsing and completely forgot about it and left it on rinse for an hour. In the meantime, it drained enough water that the water level went below the skimmer and my pump lost its prime. I have added water back up to the proper level, but I can not get my pump to re-prime. I have closed the multi-port valve and the skimmer/drain valve, added water to the pump basket and let it run for over 5 minutes several different times, but it will not prime. Did I do some major damage? Any ideas as to what I need to do next? Thanks!
