I was out vacuuming earlier, everything went fine. I putting up vac and hose. I reach over and kill the power to the pump via the timer override switch like I always do when im done vacuuming. I notice immediately that the pump filter basket goes empty. I check all connections, everything is tight, no leaks anywhere. I restart pump with override switch, and loosen the pump basket cover a bit to free up all the air in the basket, and once its nearly all gone I tightened the cover back down. I let the pump run for a few minutes until all bubbles are gone. Pool circulating fine, all valves open. (I have one underwater inlet, one for the Hayward skimmer, and the return.)
I kill the pump power again... water drains out, pump lost prime again....
1. Where is the water going? Because I cant find a leak or any water anywhere outside the pool.
2. What the ####### happened and how do I fix it?
