So a minute on and a minute off has always been the minimum rule of thumb. Two minutes on and two minutes off is just that much better for the motor. With the old conventional pressure tank method, the pressure tank fills at the rate the pump can produce, less the amount of water being used at the time.
Usually means the system is losing pressure caused by a drippy faucet or a small leak in the system.
If the home has a ten gallon per minute well pump, it's cycle time will be 3.5 minutes when called upon to fill the 119 gallon tank. Well pumps should have a minimum 2 minute cycle time to avoid premature failure.
Check the pressure switch: The pressure switch is responsible for turning the pump on and off as needed. If the switch is faulty, it can cause the pump to turn on and off too frequently, leading to short cycling. Use a multimeter to test the switch and replace it if necessary.
One of the common signs of bad water pump functionality is overheating. The pump may not leak coolant, but the pump mechanism itself may have failed. Over time the fins of the pump can actually wear down to the point where they are no longer moving coolant.

Common Causes Of Water Pump Short Cycling
The most common cause of water pump short cycling is a loss of adequate air charge in the water tank.
There is a reason gas pumps have an annoying habit of shutting off. Gas pump nozzles are designed with a device on the end that turn off the fuel flow when the gasoline runs back into it. This is a safety mechanism which prevents the gas from coming out and spilling when filling up the tank.
Thus, x = 21 hours. An electric pump can fill a tank in 3 hours. Because of a leak in the tank, it took 312 hours to fill the tank.
Starter borehole pumps can run for up to 24 hours. However, your everyday borehole pump will run between 6 & 8 hours. It is not good for your borehole pump to run continuously. If you run electrical pumps continuously, your utility bill will skyrocket.
Your well pump shouldn't run constantly. In fact, if you have this problem, you'll quickly see your electric bill going up. If you're noticing that it is, or if you're having problems with it cycling on and off repeatedly, it may be a sign of a problem.
A significant leak anywhere in the well piping lowers the water pressure in the system. So if the pressure is too low, your pump won't shut off and instead will continue running all the time.
If your pressure tank becomes waterlogged, it can lead to short cycling, which can cause your well pump to turn off at a high rate of speed and potentially burn out prematurely. If your pressure tank is waterlogged, you will need to replace the tank and pump which is costly and inconvenient.
Too Little Air in the Reservoir Tank
These tanks depend on air pressure within to regulate the pressure switch. If the inside air pressure drops, the tank will not trigger the pressure switch correctly, causing the pump to switch ON and OFF erroneously.
If the water supply pipes become clogged, the pump will short cycle. A clog in the water supply creates high water pressure very quickly. The best way to check for this is to check the water filter. If it's dirty or blocked, replace it, and you may restore function.
Pump Won't Start
There are several reasons why a booster pump doesn't start including a lack of power, water in the break tank, tripping, sensor failure, problems with the control panel and motor failure. Firstly if there is a power cut then the pumps won't run and there will be no water delivered.
Well pump short cycling refers to the situation where the pump turns on and off repeatedly within a short period. Depending on your water usage, your well pump should run for a few minutes and then stay off for a significant duration.
My pump overrun is lasting a long time - is this normal? Usually, the process for a pump overrun will last for around ten minutes. But if you notice your boiler is still running for hours after you've turned it off, there may be another problem at hand.
Another problem that a carbon dioxide test could possibly reveal is a ruptured cylinder head, which causes similar symptoms to a failed head gasket. In many cases, a cylinder head crack will be too tiny for the human eye to spot, yet it could still be a major problem.
