I'm filling my pool up now and the water has reached the inlet/return line. There was some splashing around on my filter and then water started coming out the blue flat drain hose. I've got water filing the hoses and I don't want to take anything apart unless needed at this point and none of the openings on the multi-port are marked (I even have the book and it's not clear!). The filter handle is in the "Filter position" right now. Does this mean the opening to the skimmer is mis-hosed? Please help!
I'm fairly sure the hose from the pump to the filter (elbow) is correct.
