DG,
Glad you got it running... I have the useless SVRS option on my IntelliFlo, and have found that low water, when trying to prime, will often cause mine to go into the entrapment mode and shut the pump off. It will also shut off if I close the air relief valve on the filter too quickly... For my pump anyway, you have to push the reset button to clear the fault, otherwise it will try to prime several times and then shut off altogether.
I run my pump 24/7 for a number of reasons, but one of them is so that I don't have to prime everyday...
Thanks,
Jim R.
