Consumer reports says a well pump runs about 700 watts. Multiply that by 3 to get a rough estimate of the starting wattage for the pump and you run about 2100 which still leaves plenty of wiggle room in terms of wattage. How many watts does a well pump draw?
How many amps does a well pump use?
This is a common pump style for well pumps, and it is often 240 volts and 1 HP. This means that it will draw 10 amps of current, but when started, it might draw as much as 35 amps. The higher draw will only last for 5-10 seconds in most cases. A shallow well pump might need a lot of wattage, and they can be quite loud.
What size generator do I need for a submersible well pump?

How to determine wattage of well pump?
To determine your well pump’s wattage, you have to know the horsepower. And to know the horsepower, you have to know the size of the well pump. All this is determined by how much water is needed. But there are many different sizes of pumps depending on what size household or community is using the well.
What are the different types of well pumps?
There are four different types of well pumps that are most commonly used. These include the submersible pump, jet pump, turbine pump, and cylinder pump.
How many watts does a generator need?

How does a water pump work?
Most water systems also include a pressure or hydropneumatic tank, which is a water storage container. This is usually found in a utility room or basement but may also be underground in some cases. The pressure tank does several things including: 1 Providing a reserve supply of water for times of highest demand 2 Building up a new reserve supply of water every time the pump runs so it does not have to start and stop as often 3 To store the water and provide you water when the pump is not running
What is a well pump?
The well pump is the motorized unit that pumps the water from the well casing to the surface when it is needed.
How to find out how much horsepower a water pump needs?
The water horsepower needed equals the minimum power that is needed to run the pump.
What is a well screen?
The cap also has a vent that helps control the pressure while the well is pumping. The well screen on the bottom of the casing helps keep sediment out of the well. They are typically made of a perforated pipe, slotted pipe, or a continuous slot.
How many watts does a shallow well pump use?
A shallow well pump might need a lot of wattage, and they can be quite loud. These well pumps draw about 750 watts running and 15-1800 when starting.
How many volts does a pump use?

How many amps does a jet pump need?
Jet pump style well pumps can vary in size from ½ HP to 1 ½ HP. This style of well pump will usually need anywhere from 10.8-21.04 max amps to run. The lower end of the run amps will be lower for this style at 5.4-10.7 amps.
How many amps does a 1.5 HP submersible pump meter out?
A submersible pump that is 230 v with a 1.5 HP motor will meter out at about 11.4 amps per leg. This is an average size pump, but you might find that your unique pump carries more or less amperage based on the arrangement of the motor.
How much power does a pump need?
As a rule, the bigger the pump, the more electricity that it will need to both run and start. Smaller pumps might only need about 10-35 watts while running, and larger or more powerful pumps might need as much as 25 watts and up.
Can you see what amperage is being drawn?
It is not always possible to go and look at the actual equipment to see what amperage is being drawn when it is in use. This is not a concern with above-ground units, but that is rarely where these pumps are located.
How many volts does a well pump need?
Most submersible well pumps are 230 volts and require a 2 pole circuit breaker (2 circuit breakers connected together).
How many watts does a pump produce?
Pumps are rated by the usable work that they perform after all the electrical and mechanical inefficiencies have been lost. The pump may produce 1 HP/946 watts of usable water flow/pressure, but the actual amount of power required to do this is a bit higher due to the inefficiencies.
What is the label on a submersible pump?
This label has information like how many horsepower or kilowatts the motor is rated for, how many amps the motor is expected to use and the voltage that the pump needs to run properly. Finding this label on the above ground pump is usually the work of just a few seconds, but what about the submersible pump? It is often located hundreds of feet in the ground!
How to check if a well pump has 4 wires?
If you want to double check and you have a 4 wire motor, shut the power off to the well pump , disconnect the yellow, black and red wires, switch the T6-600 to the Omega sign (for resistance readings in ohms) and touch the red/black tester leads to the red and black wires that lead to the pump and write the number down.

What is a 40 amp breaker?
A 40 amp breaker means the pump is smaller than 3 hp will use ~14 amps/3000 watts during operation. A 50 amp breaker means the pump is smaller than 5 hp will use ~25amps/5500 watts during operation. NOTICE that the circuit breaker is significantly larger than the amount of current/amperage the pump uses during operation.
How to Determine the Voltage of a Well Pump?
Determining your well pump’s proper voltage is essential. Running your system on the wrong voltage is not advisable. Your pump would perhaps refuse to operate. Moreover, you can damage it as you let it run on higher amps.
What voltage is a submersible pump?
First, most old submersible pumps are 220V. This is particularly true for those that people install in deep wells.
Why do you need a bigger well pump?
In other cases, you’re drawing from a much deeper well. In this situation, you will need to use a larger pump. Large pumps use 220V. Because they require more voltage to start. And using a larger 220V well pump for a deep well will cost you a lot less eventually. The case is the same for situations that you have a much longer wire requirement. This is because the higher voltage allows the pump to run more smoothly. This is true even with heavier loads. It can last you longer than a 110V pump would.
How far can you run a well pump?
In some cases, you’re drawing from a shallow well. This only requires less than a 100-foot wire to run. But getting a dual voltage well pump that can run on either 110V or 220V would be your best option. This is in case you eventually require more than a 100-foot wire to run your pump. When you switch it to 220V, you can go up to 400 feet with the wire connection.
How many terminals are there in a 240V pump?
240V pumps use pressure switches with 4 terminals. The 2 outer terminals are for the breaker box, while the 2 inner terminals connect to the control box.
Why can't a pump build enough pressure?
The pump can’t build enough pressure. Because the power output is considerably reduced. Moreover, the water supply won’t be as reliable. And it’s because of the weak water pressure.
Can you run a 220V generator with 110V?
As we mentioned earlier, it’s always advisable to run any motor or device on its designated voltage. You may think of running a 220V with a 110V generator. But the pressure will be substantially weaker. Not only that, it can overheat and burn up your pump motor as well. And not to mention the damage it might do to your generator too.
