stagecrewgod said:The "Vacuum Hose end" appears to be an vacuum adaptor. On the skimmer next to the suction port it says WHITE and next to the "Main Drain" port it says BLUE. My vacuum has a white end and blue end. Is there something behind this? Thanks!
The adapter being in there is probably blocking half of your flow from the drain or from both the drain and skimmer, depending where it is.
