With my old Hayward pump, when I would open up the leaf trap I wouldn't lose much water from the pump basket area - maybe an inch or two. With the Pentair VS3050, every time I've opened it to clean out the basket all of the water siphons out? Should I be opening the filter air relief on the filter to try to offset the suction? I've been lucky and the pump has reprimed a few times, but this morning I had to pull out the hose and fill the pump which I never had to do with the old pump :grrrr:
