Now I think I have it. Just get the suction going the old fashioned way, eh? One follow up - I do have a door to my deck very close to all of my tanks. What's the best way to get suction going? I can't imagine you could suck on the end of the hose and run back to tank????
Thanks for the suggestions - I will also check all of the parts for debris.
