Water Pump turning on and off

Why does the water pump in my apartment turns its self on for a few seconds every minute or two all the time.

This is more than likely caused by a dripping tap even just a few drips can drop the pressure in the pipes and cause the pump to turn on and bring the pressure back up.

Another possible cause is a leaking ball valve in a toilet cistern, many cisterns over flow internally into  toilet its self so you might never know you have a leak.

Apart from being annoying a pump turning on and off that frequently will have a shortened lifespan. Fixing a dripping tap or a leaking valve is a lot cheaper than replacing a water pump.
