In the process of replacing some of my pool plumbing, the water level in the pool dropped a foot or so. After I got the plumbing replaced, I forced water into the skimmer inputs. The input from the skimmers to the pump seems ok, but there is very little input from the bottom drain. I think the problem is air in the line to the bottom drain, but I can't figure out how to get the circulation going again. Any ideas?
