Opening my 15x30 AGP for the first time. It has a typical water-line skimmer, but also has 2 floor drains(??? Discs in the bottom that return water to the Filter-IN line, WHEN OPENED).
Bought the house last summer, and I know that the previous owners had the floor drains CLOSED, and NOT running water to the filter during normal operation - not sure if that is b/c I'm not supposed to have them opened, or if they just left them closed to preserve their winterization.
Seems like I was told somewhere on TFP that I should OPEN them, that it will help with pool circulation. Is that correct? Should I open them? If so, should I open them up all the way? Won't that cut down on water going through the skimmer, and thus reduce skimmer efficiency? (although there is the basked at the front of the filter, so I guess it is likely irrelevant which path the water takes to get to the filter?)
