Why does my spa keep draining into my pool?
Normally if a pool system is perfect, it’s sealed so that the water won’t drain out from the pump or anywhere else when it shuts off, but if there’s an air leak, it loses that seal and everything floods back to the pool. That’s another reason why your spa could drain out.
How does spa check valve work?
A check valve in easy terms is a valve that allows water to only go one way/direction. So if you have a raised spa water can only go TO the spa and when the pump turns off the valve shuts not allowing the water to go backwards inside your plumbing allowing the water level in the spa stay put.
Where is my spa check valve?
As such, a common location for a check valve is on the incoming suction pipe, in front of the filter pump.

The function of the Check Valve is to stop water from doing what it naturally does when the pool turns off, which is to flow in the direction of least resistance which is back down the pipe into the pool.
