spa water level drops
Lately I've noticed that my spa water level drops to the level of the pool when the pump is not running. It is a slow gradual drop. I have a spa that is raised 6" above the level of the deck. The spa has a spillway that circulates into the pool when the pump is running
What could be causing this? I don't believe the water is leaking out because when the pump is running the water level raises back up to the level of the spillway and the water level in the pool seem to be holding steady.
