I think the bottom picture is a skimmer? Is there water in it?
All the valve's look to be open, there is a SWG on there.. I do not see any pressure after the SWG on the pressure gauge.. but there is pressure in the filter (unless that is broken) Is there a valve or blockage between the filter and the heater/SWG ?
I don't think that is possible so the pressure gauge is probably broken.
It looks like the suction valves are set properly in the picture so my only suggestion is that there might be something blocking the skimmer line. To test this theory or perhaps clear the blockage, can you turn off the other suction line so the skimmer is the only thing that is active? If the filter pressure goes down a lot or you get a lot of air in the pump basket, the line is probably blocked.
Not sure what the 2 vertical pipes leads too but it goes to the overhead. I closed the main drain valve got some circulation in the skimmers pressure gauge jumped up to 7
Do you mean Pentair? I think that is the motor number but good enough for an ID.
Best I can tell, things are working as they should. The pump is an up rated 1 HP so it is not very big and the pressure and suction will not be all that high with that pump. The flow rate and head loss perfectly match a Challenger pump's head curve B which is for the up rated 1 HP. So that looks good too.
If the skimmer was plugged, the suction would be much higher than 7" hg. It just may be that you can't tell the water is going into the skimmer. You might try throwing something that floats in front of the skimmer and see if it gets drawn in.
