I have a well that supplies only outdoor water faucet water. Inside water is municipal. The well has a submersible pump and there is no water tank. I've never had a well before. All works reasonably well except when I am not consuming water, the pump kicks on and off about every 15 minutes. My water pressure is 50 psi and I don't really notice the pressure drop that should cause the pump to kick on. Nothing appears to be leaking either. The on/off is annoying. I'm in the habit of turning the pump off when not in use however the switch is hidden down in the basement so its a pain to have to turn on/off each use - mostly in summer when watering plants outdoors. I'd prefer to leave it on but the cycling is irritating. Is this a standard thing or a sign of some abnormal issue?
