But Some Things Last Longer Than Others

Turned out it wasn't the pump after all.  It was the pressure switch.  In addition to calling the well driller, I called the regular plumbing and heating guy and also left him a message.  He called me back at 8:00 AM and said he would be there between 10:00 and 11:00.  He showed up promptly at 10:00 and had the problem fixed by 10:15. It's only a temporary fix though.  The switch needs to be replaced as well as the pressure tank.  He said that he might be able to do it tomorrow or next week for sure.  Meanwhile we have running water in the house again.  Yay!
