Water leaks in wells, I just pulled my well pump out at a mere 390 feet,
older galvanized 11/4 « steel, where the Water rose and dropped the pipe
was is poor shape, not leaking yet but it will l suggest if the pump is pul
l Ed then replace it with well pipe either sch 80 or 120 depending on the
depth.
Fun times
