Question

My well pump comes on every 30 minutes without water usage. There are no leaks. Any ideas?

Answer 1

Could be a leak in the pressure tank. Check all toilets since they can leak from the tank to the bowl without showing up well.

Answer 2

check valve leak at the well point?

Answer 3

check the pressure in your pressure tank. May need to be reset.  

Answer 4

Probably in the pipe to the pump (If submersible) or to the foot valve if above ground pump. I have had problems with foot valve getting gravel in them causing water to leak back into well. I would shut water off at pump going into house. See if pump still cycles on and off, if so and you see no sign of leakage in well house. You will then have to pull (or have pulled) the pipe out of well. When doing this keep close watch for water coming from pin hole in pipe. If PVC pipe you can cut out bad section and add coupling.  

Answer 5

It is maintaining pressure in the system.  Yes there is a leak.  In the  pump itself.
