I recently replaced the pump on a deep well after the shaft sheared. Prior to this our water pressure was fairly decent. After replacing the pump the water pressure starts off good but quickly peters out. I have a galvanized pressure tank with 40-60 cut-in cut-out setting. I drained the tank completely to make sure there was an air charge but that didn’t help at all. Is there anything else I can try? Would it be wise to replace the galvanized tank? If so, should I replace it with another galvanized tank or should I go with a bladder tank? Are there any gotchas associated with switching from one type of tank to the other?
