    What was the setting on the pressurtrol? Cut in should be .5 psi, differential to setting 1.
    Remove the pressurtrol and see if you can blow into the pigtail. It's likely clogged and needs to be cleaned.

    What @HVACNUT said. And, if the pigtail is steel, replace it with a brass one that won't fill with rust.

    Thanks. THe settings on pressurtrolwere 0.5 and 1 on the inside wheel. I removed the pigtail and it was completely clogged. Water couldnt go through. I used copper #12 copper wire, wd40 and and brake cleaner to clean it. Problem solved.
