My spa overflows into the pool, when running. I’ve noticed that we are losing water. I turned the flow off to my spa, and during a week, it has drained about halfway down. I haven’t noticed any loss of water in the pool, not like it has been. The level of the spa water, normally is about 8-10” higher than the pool water. With the spa flow off, the water has drained down, and the spa water level is about 2 - 2 1/2” lower than the pool level. I was told that the “back-flow” valve might be leaking. Is that the same as the check valve? I can see where that check valve is, and i have never seen any sign of it leaking. Would there be another valve underground that could be leaking?

Yes, the check valve is the same thing as the back-flow valve. The check valve is the most common reason for a spa to drain lower than normal. You wouldn't notice water leaking outside of the check valve. It would drain through the pipe and back to the pool.
