It is an inground pool. I am at work now so I can not tell you what brand the pump or filter is. I was worried about running it too long without water flowing through it so the longest I let it run was maybe 15 seconds. Do I need to let it run longer? I placed a hose directly in the pump filter and I did notice a pinkish liquid coming out of one of the skimmers in the pool. I assume it was antifreeze. Are all lines to and from the pump supposed to be open while priming?
