I have a 2HP hayward Northstar.
Have not a single issue with it, until Hurricane Ike and lack of power.
Not sure if that is the reason, but since power was restored (16 days no running) about every other day the water level in the pump basket falls low enough to be below the impeller station.
I can not see any leaks, but I do know that if I open a valve or air release all the water will drain out of the filter and lines, but still be above the impeller. So this whole below the impeller thing is throwing me off.
If I fill the basket so water is in the impeller, it creates prime and starts working fine.
So something is leaking the water out to below the impeller inlet. But I am clueless at this point.
