Check Valve Orientation

[sansters]

I'm having what I think are check valve problems - the spa is draining while the pool is off. I've changed the valve on the left, and the valve on the right is facing sideways so I've left that alone. The problem is still there. It looks like I've had this issue before in this forum but never got confirmation if the valve on the right is facing the right way or is it intentionally sideways?

For the check valve on the right there should be an arrow on the window of the check valve, it should be pointing at the pump. It also looks like your return diverter is set for spa fill(based on bypass/equalizer) and intake diverter is pool suction.
