I have a friend who has the Jandy JVA's. I was there the other day and noticed that when they rotated from pool to spa, they rotated the wrong direction and dead headed both the intake and output feed of the Jandy valves. His Jandy valves are standard, using the middle ports as input and output to the pump.
The JVA's are mounted 180 degrees from what I would consider the normal mounting position. Have these been installed wrong?
I think that what I should do is take them off and rotate 180 degrees and re-install. Then flip the switches on both JVA's from the current position to the other position.
Does this sound right?
