Helped my father replace his shallow well pump with a Gould j05 pump with bladder tank. The pump is about 3 feet from the well head. The pump was primed but will not biuld presure. The well has two pipes and is about 35 feet deep. He did have a old rubber hose on the suction side and would collapse when the pump ran, this was replaced with PVC. I am not sure were to start trouble shooting the problem.
