What is a Sump Pump Float Switch?
The float switch is a component of the sump pump that rises and falls with water levels. Depending on these movements, it is responsible for activating and deactivating the motor.
The float switch is not heavy, and it hangs loosely from the arm to allow it to rise when the basin is filled with water.

How to Install a Float Switch on the Sump Pump
Replacing and installing a float switch can be a little tricky, especially if you are inexperienced in plumbing. Installing a float switch can be done at home, but you can also hire a professional to help with the process. There are a couple of ways you can go about installing;
- 1Replacing the older one with the same switch type.
- 2Replacing with a different float switch kind.
You need these items for the installation process;
Step One
Begin by emptying your sump pit. Run the pump until it is empty. After emptying the pit, disconnect the pump from the main power supply.
Step Two
Locate the float switch that you will be replacing. The float switch is attached either to the pump's side or found at the pit's bottom. Locate and remove it.
Step Three
Dismantle the float switch. After removing it from the pump, use the screwdriver to open up its casing and take note of the defective switch. Attach the new float switch and apply the waterproof glue.
Allow the glue time to dry off, after which you can reassemble the float switch parts together. If you are adding another float switch to the existing one, at this stage, you can bypass the wiring of the last switch and attach it with the new switch.
Step Four
Connect the float switch to the sump pump and ensure all the parts are properly sealed off. Return the pump to its pit. Run the pump to ensure everything is running smoothly.
What are the Benefits of a Float Switch?
There are different benefits for installing a float switch into your sump pump. Below is a comprehensive list of benefits of a float switch.
1. Eliminates the potential for water damage.
One of the most significant benefits of a sump pump float switch is that it reduces the potential for overflow, leading to water damage to the surrounding floor or ground surfaces.
When the water reaches the required level, the float switch automatically deactivates the sump pump, eliminating excess overflow.
2. Low potential for components to fail.
Given that it is a simple switch mechanism, it is less likely for components to malfunction when compared to other more complicated devices.
3. Low Cost
Another benefit of a sump pump float switch is that it is a low-cost feature that is easy to purchase and install. If the sump pump does not come equipped, the float switch can be installed by a technician at a reasonably affordable cost.
4. It reduces most and other microbial growth.
In addition to avoiding water damage, the automatic switch-off of the sump pump will remove the potential for the growth of mold in overflowed surfaces around the unit. This leads to a healthier environment.
5. It is effective
An automatic float switch activates and deactivates on its own depending on the water level. This reduces having to manually turn the pump on and off every time the water level rises and falls. It can work automatically at any time of the day and night.
6. Longer life for the sump pump
The majority of sump pumps fail because the float switch was unable to function. While sump pump float switches can be replaced or repaired, it only happens after severe damage in the basements or crawl spaces.
An excellent durable float switch will save you from dealing with a dysfunctional pump machine and a messy basement.
What to Consider When Choosing a Sump Pump Float Switch
Below are several factors to consider when purchasing a float switch.
1. The Type of Switch
Float switches come in two different types, and each functions differently from the other.
2. The Size of the Switch
Different sump pumps have various sizes of float switches. Therefore, when shopping for a float switch, ensure it is compatible with the sump pump you have at home.
It should ultimately be the correct fit and size for the sump pump. If it fails to fit the pump well, expect mediocre and unsatisfying performance from the pump.
3. Ease of Installation.
If you are going to install it on your own, you should consider purchasing one that is easy to install and use. Ensure the float switch has the appropriate features that will make it easy to install.
4. The Float Switch Build
the float switch should be designed with materials that are rust and corrosion-resistant. Many sump pumps are submersible, and this means the float switch will come in constant contact with debris and minerals in the water.
Since the float switch will contact such humid conditions, it is vital to ensure the switch is waterproof. The float switch should be made with sturdy materials too to ensure durability.
5. Is the Float Switch Electronic?
The majority of float switches function electronically. You should consider a float switch that features a water level sensor technology instead of having components that work mechanically. Some switches run automatically after detecting the water levels.
6. Is the Plug Piggyback?
The main advantage of having a piggyback plug is the ability to test the sump pump independently. Your work is to disconnect the cords from the wall and ensure they stay separate. Once it is done, you connect the pump to the outlet without the switch.
7. Alarm Systems
Some sump pumps come with an alarm system to alert you when it detects a problem while pumping the water.
8. Power Cord Length
It would help if you chose a model with at least ten feet cord to allow it to reach the basin from the power outlet. Using an extension cord can be an alternative. However, it is hazardous since it can short out or cause a fire outbreak.
Who Needs a Float Switch?
Sump pumps need a float switch to function. Without the float switch, the motor does not know precisely when to activate itself when the water level rises in the sump pump. Even the most powerful pump will not function if it doesn't know how to start and deactivate itself.
Homeowners who have a sump pump should ensure they have a float switch installed on their sump pumps. They should also have replacement float switches just in case the existing ones fail to function.
FAQs About the Sump Pump Float Switch
Q: Where is the float switch located on the sump pump?
A: The float switch can be located internally or externally. It is usually adjustable to allow the perfect fit with your water line and basin.
Q: How does a float switch work?
A: The float switch functions like an arm hanging off the side of the pump’s unit with a buoy attached.
Q: Why does a float switch fail?
A: Using an extension cord often results in overheating of the sump pump. Therefore, when the power source fluctuates in providing power, the float switch, despite functioning, won't turn the pump on.
This eventually stops the float switch from functioning. Float switches also get clogged, which prevents the switch from rising up the base, making it dysfunctional.

It is extremely important to make the best choice when you need a sump pump float switch replacement because, without one, you cannot make a sump pump run.
We recommend using the Superior Pump 92010 switch due to its amazing features at a reasonable price. In fact, it’s the best sump pump float switch for us.
