A regulated return might help if the pump isn't faulty. I don't run the ad2s for their regulated setup or reliability.

just called pureflow they told me its sucking air.....

Yup. Never ran it with pureflows wimpy excuse of a wiring harness. Made my own heavy gauge harness.

Sump with an NPT and only 3 fittings between it and the pump...... hmmmm if it's sucking air... the installer did a major fail, and there should be a leak. I don't think that's the problem.
