House is in northern maine, on an Artisian well, Am using a jet style goulds pump, pump is loosing it prime, and when the pump is running, I get only about 27 PSI, pump was in the basement of old house. basement was filled in and concrete slab poured for new house, lines were spliced and buried. I think I already know the answer to this question but am just making sure im right. either im leaking air somewhere in the line or the jet is clogged.
