Mary- I tried to E-mail you because this might get involved, but they say your address is bad. So lets try to solve this one step at a time. Find your pressure guage, it should be near a tank where the well line comes into the house , or outside in a well house. Run some water and read the lowest point the pressure gets to before it starts going back up. That is the cut-in pressure- what is it? Turn off the water and make sure none is being used, running toilets, drippy faucets, etc. The pressure should increase and finally stabalize. That is the cut-out pressure- what is it? Now watch the guage for 5-10 minutes. Does the pressure remain the same or slowly drop?
