Well, I hope the valve is serviceable because you do not have any clear pipe to re-plumb.
If the check valve is dead, you likely have to cut out and replace the Jandy valve, the flow sensor, and the union going to the SWG.
Or you could cut out the Ortega and use a smaller pipe glued to the inside of the Jandy valve, and then maybe turn down and add a Jandy/Pentair check valve vertically.
