Correspondingly, what causes a well pump to cycle on and off?
Short cycling of a water pump which is defined at SHORT CYCLING WATER PUMP means that the water pump or "well pump" turns on and off too rapidly or too frequently when water is being run in the building. The most-common cause of pump short-cycling is loss of air in the water pressure tank.
Beside above, should a well pump run constantly? When a well pump is running all the time and will not shut off the most common reason is that the well pump is not able to build enough pressure in the system to tell the pressure switch to turn the well pump off. Another common cause could be a leak in the plumbing from the well to the home.
Herein, how many times should a well pump cycle?
Even 1/2 HP pumps are recommended to have at least a 1 minute run time. Actually it stated as 300 cycles per day. And since there are 1440 minutes in a day, that would be a cycle every 4.8 minutes max. If the pump only needs to pump 8 gallons then it don't take long.
Why is my pressure short cycling?
Loss of air charge is, perhaps, the most common reasons your water pump will short cycle. If it's in the upper 70% of the tank, then that means there's not much air reserve, and likely this is the cause of your pump short cycling. To fix this, first make sure the air volume control valve is not dirty or leaking.
