Newbie here.....We just opened our pool this weekend and I am completely drawing a blank regarding how the 3-way valves should be positioned. One valve can turn off/on the spa drain (set to off), another valve controls the skimmers (both on), and the third valve controls the pool drain (set to open). Is this the right configuration? The only reason I am questioning this setup, is the pump, when turned on, is very loud, and doesn't seem to be fully primed (water is flowing, but water in basket doesn't reach the top of the lid). Another issue which concerns me, when I manually vacuum the pool, the pump loses its pressure after a couple minutes (one skimmer is off and the pool drain is set to off). I can't seem to "fully" prime/fill the filter basket.
I included a picture to show you the setup. Pump/DE filter is at the top.
Any help would be greatly appreciated.
Thank you in advance!
