I have been having problems with my deep well pump since it was put in in 1989. The bladder tank will run dry and I have to manually reset the pump. There is no rhyme or reason as to when it does this and I can found no pattern; like excessive loads; and it's not like the well is run low because I've never had to let it recover. I have replaced both the bladder tank and the pressure switch several times over the years, as well as having the well fractured, and still have the problem. Anyone with ideas. I've run out of things to try.
