Understanding Amps and Horsepower
Amps and horsepower are two terms that are commonly used to describe the power of a pool pump. Understanding these terms is crucial if you want to make informed decisions about your pool’s equipment.
Amps are a measure of the amount of electrical current that is flowing through a circuit. A pool pump’s amp rating refers to the amount of current that it draws when it’s running. This is important because your pool’s electrical system is designed to handle a certain amount of current.
Horsepower is a measure of power. In the context of a pool pump, it refers to the amount of work that the pump can do in a certain amount of time. A higher horsepower rating means that the pump can move more water and do so more quickly.
It’s important to understand the relationship between amps and horsepower because they are related. A higher horsepower rating generally means that the pump will draw more amps when it’s running.
In general, you want to choose a pump with a horsepower rating that’s appropriate for the size of your pool. A pump with too low a horsepower rating will struggle to keep your pool clean, while a pump with too high a rating will draw more amps than necessary and increase your energy costs.
Now that you have a basic understanding of amps and horsepower, let’s take a look at some of the factors that can affect the amount of current that a pool pump draws.
The Relationship Between Amps and Horsepower
Understanding the relationship between amps and horsepower is crucial when dealing with pool pumps. The two are interdependent, and knowing how to calculate one from the other can help you make informed decisions about your pool pump.
First, it’s important to note that horsepower is a measure of power, while amps are a measure of current. A 1 HP pool pump will generally pull between 10-15 amps of current, but this can vary based on a few different factors.
One way to think about the relationship between amps and horsepower is that amps are the “workload” that the motor is carrying, while horsepower is the “capacity” of the motor to do that work. So, a motor with a higher horsepower rating will be able to handle a higher workload, meaning it will draw more amps.
It’s also worth noting that a pool pump’s amp draw can fluctuate based on how hard the pump is working. For example, if you’re running your pool pump at a higher speed, it will likely draw more amps than if it’s running at a lower speed.
Overall, understanding the relationship between amps and horsepower is important when choosing a pool pump and when making decisions about how to run your pool efficiently. By knowing how to calculate one from the other, you can make informed decisions about your pool’s energy usage.
How to Convert Horsepower to Amps
If you want to know how many amps your 1 horsepower pool pump draws, you’ll need to use a conversion formula. The formula for converting horsepower to amps is:
- Multiply the horsepower rating by 74For example, 1 horsepower x 746 = 746.
- Divide the result by the voltage of the circuit. For example, if your circuit is 120 volts, then 746 ÷ 120 = 6.22 amps.
- Remember that this calculation is only an estimate, and actual amp draw may vary depending on the specific pump and other factors.
If you don’t know the voltage of your circuit, you can use a multimeter to measure it. Make sure to turn off the power to the circuit before using the multimeter to avoid electrocution.
It’s important to note that this calculation only applies to the power consumption of the motor. Other components, such as the pump, filter, and heater, will also draw power and contribute to the overall electrical load of your pool system.

|---|---|---|
| Flow Rate | 50 GPM | |
| Total Dynamic Head (TDH) | 50 feet | |
| Power | 1 HP |
To determine the size of the pool pump required for your swimming pool, you need to calculate the flow rate and the total dynamic head (TDH) of your pool. Once you have these values, you can use them to find the correct size of pool pump for your needs. In this example, we will use a 1 HP pool pump and the following values: a flow rate of 50 gallons per minute and a TDH of 50 feet.
To calculate the head loss in the pool plumbing, you will need to add up the friction losses and the dynamic head losses. Friction losses occur when water flows through pipes, fittings, and valves. Dynamic head losses are caused by the resistance of the water to flow through the pool’s features, such as the skimmers, main drain, and return lines. In this example, we will assume a total head loss of 50 feet.
To calculate the power consumption of the pool pump, you will need to know the efficiency of the pump. Efficiency is the ratio of the output power to the input power, expressed as a percentage. In this example, we will assume an efficiency of 80%, which means that 80% of the power consumed by the pool pump is used to move water through the system, while the remaining 20% is lost as heat.

How to Reduce Amp Draw in Your Pool Pump
If you’re concerned about the energy usage of your pool pump, there are several steps you can take to reduce its amp draw. Reducing amp draw means that your pool pump will use less electricity, which can save you money on your energy bills.
The first step to reducing your pool pump’s amp draw is to make sure that your pool’s water circulation system is properly balanced. An unbalanced system can cause the pump to work harder than necessary, leading to increased energy usage. Ensure that your pool’s water returns are evenly spaced and that the pool skimmer is not obstructed.
Cleaning your pool pump’s filter is also an essential part of reducing amp draw. A clogged filter can cause the pump to work harder than necessary to circulate water, leading to increased energy usage. Make sure to clean your pool pump’s filter regularly, especially during periods of heavy pool use.
Installing a variable-speed pool pump is another way to reduce amp draw. These pumps can adjust their speed to match the water flow requirements of your pool, which can lead to significant energy savings. While a variable-speed pump may be more expensive than a traditional single-speed pump, the energy savings over time can make up for the initial investment.
Finally, reducing the amount of time your pool pump runs each day can also help to lower its amp draw. Most pools only need to run their pumps for 6-8 hours per day to maintain proper water circulation. Consider using a timer or automated pool control system to regulate your pump’s run time.
Regular Maintenance and Cleaning
Regular maintenance and cleaning of your pool pump can help reduce its amp draw and increase its efficiency. It’s essential to clean the pump’s basket and filter regularly to avoid debris buildup that could affect its performance. Ensure you also check the impeller and pump housing for any clogs or damage that could cause the pump to work harder than necessary.
Check the motor bearings for any wear and tear that could result in extra friction and more energy consumption. Replace any worn out bearings immediately to avoid any further damage to the motor.
Monitor the pump’s operation and look out for any unusual noises or vibrations. If you notice any problems, turn off the pump immediately and inspect it for any damage.
