Howdy gents. I've had a Pentair Intelliflo VS installed since last June. It worked perfectly all summer and for the first time ever I didn't battle algae in the hot months.
Problem though, I can't get the dang thing to prime for the life of me! It starts up, ramps up to top speed and reads "priming". Occasionally it pulls in large amounts of water, but the second the power reverts back to a lower setting, BAM! The basket empties and it runs dry for a period before giving me the alarm and shutting off. Other times it will never start out pulling water, just a trickle from the pool to the pump. The basket sits mostly empty. When I add water per the manual, it drains backward, into the pool and never stays in the basket. I've tried bleeding the air from the filter until water shoots out and that works off and on, but I just can't get this thing to prime and run with a full flow of water. Any thoughts? I've read the old thread where a guy had similar problems, but mine seems different. It's not the "priming time" it's that the dang basket is empty and therefore the pump can't prime itself. Pump is only about 12-18" above pool surface. Thanks for the help.
