If you’re a homeowner who wants to ensure that your sump pump motor runs smoothly and efficiently, attaching a capacitor to it can be a great idea. Capacitors are electrical components that store energy and help regulate the flow of electricity in a motor. By attaching a capacitor to your sump pump motor, you can help it run more efficiently and effectively, which can save you money on your energy bills and extend the life of your pump.
In this guide, we’ll walk you through the steps of attaching a capacitor to a sump pump motor, so you can keep your home safe and dry with confidence.
Understanding Capacitors and Sump Pump Motors
Capacitors are electrical devices that store energy in an electric field. They are commonly used in motors to start and run them efficiently. Capacitors are also used in sump pump motors to provide an extra boost of power when the pump starts up.
Sump pump motors are designed to remove water from basements and other areas prone to flooding. They are typically powered by electricity and use impellers to move water out of the area. Capacitors are important components in sump pump motors because they help to regulate the amount of power that is supplied to the motor.
When a sump pump motor is turned on, it requires a large amount of power to get started. Capacitors provide this extra power by storing energy and releasing it quickly when it is needed. This helps to ensure that the motor starts up quickly and efficiently, which is important in emergency situations where flooding is imminent.
It is important to note that capacitors can be dangerous if they are not handled properly. They can store a significant amount of energy and can discharge it quickly if they are shorted out.
Safety Precautions
When working with a sump pump motor, it is important to take certain safety precautions to avoid injury or damage to the equipment. Here are some safety measures that should be taken when attaching a capacitor to a sump pump motor:
- Wear safety gear: Capacitors are known to explode when shorted out, so it is important to wear safety gear like goggles, helmets, or eye protection to protect yourself from any potential harm.
- Turn off the power: Before working on the sump pump motor, make sure to turn off the power to avoid any electrical shocks. To do this, switch off the circuit breaker that supplies power to the sump pump motor.
- Discharge the capacitor: Capacitors store electrical energy even when the power is turned off. To avoid any electrical shocks, discharge the capacitor by shorting the terminals with a screwdriver or a resistor.
- Check the voltage rating: Make sure to use a capacitor with the correct voltage rating for the sump pump motor. Using a capacitor with a lower voltage rating can cause the capacitor to fail, while using a capacitor with a higher voltage rating can damage the motor.
- Follow the manufacturer’s instructions: Always follow the manufacturer’s instructions when attaching a capacitor to a sump pump motor. This will ensure that the capacitor is installed correctly and that the sump pump motor operates safely and efficiently.
By taking these simple precautions, you can ensure that the process of attaching a capacitor to a sump pump motor is done safely and without mishap.

Attaching a Capacitor to a Sump Pump Motor
- Start by turning off the power to the sump pump and also turning off the power at the circuit breaker.
- Depending on the brand and model of the sump pump, you can find the capacitor under the pump cover or on top of the motor. You can also take a look under the electrical end of the motor. If you’re unsure, check the manual for the exact location.
- Sump pumps tend to have both a run capacitor and a start capacitor. The rating of a start capacitor will be around 50-400 MFD and 125 VAC. On the other hand, it will be around 15-50 MFD and 370 VAC for the run capacitor.
- The cover protecting the capacitor will be held on by several screws. Remove all the screws, take the cover off and you’ll see the capacitor.
- Don’t touch the capacitor yet, because a full pump capacitor actually stores an electrical charge and may shock you even after the power is off.
- Before you try to remove the capacitor, you need to discharge this energy. To do this, place a screwdriver in the middle of the capacitor and across the leads.
- Remove the screws holding the capacitor in place.
- We highly recommend that before removing the leads you take a picture so that you can easily and correctly restore them as soon as you’ve added the new capacitor.
- Once the new capacitor is in place, it’s time to connect the motor leads to the sump pump capacitor and secure the capacitor in place. Also, look closely at the placement of the plastic strip.
- Place the cover in the exact position. Tighten all the screws and re-establish the power at the circuit breaker.
Conclusion
By following the steps outlined in this guide, you should now be able to attach a capacitor to your sump pump motor with ease. Remember to always take safety precautions when working with electrical components, such as turning off the power before beginning any work, and using the proper tools and equipment.
By adding a capacitor to your sump pump motor, you can help ensure that it runs efficiently and effectively, which can provide you with peace of mind during heavy rainfalls or flooding. With this simple upgrade, you can help protect your home and keep your sump pump running smoothly for years to come.
