A few days ago the Jandy Actuator Valve failed and caused all of the water to be sucked out of the spa and into the pool through the pump. A day passed before I noticed. When I noticed the problem, I quickly refilled the spa and replaced the valve, unfortunately not before a lot of air was sucked into the pump.
Once I got the spa refilled and manually changed the valve to pull from the pool, the pump started right back up. Over the last several days I've noticed the pool isn't looking as good as usual and the pump isn't completely full of water as it should be. I can tell through the window where I take the filter basket out that its sometimes only half full of water.
When I take the lid off the pump, the water fills the pump so there's no need to use a hose to fill it. I've tried to open the air release valve on the filter. When I do this air comes out, but so does a lot of water. All of the instructions I've found say to close the air release valve once you get water coming out.
