Factors to Consider for Choosing the Best Sump Pump Float Switch

Sump Pump Float Switch

When selecting the perfect and good working float switch, it’s essential to weigh all of your options. From type and size to weight, each factor is key for keeping your system running seamlessly. So let’s dive into what features make a great sump pump switch.

1. Type of Float Switch

When shopping for a sump pump, decide which float switch type is best to fit your needs. Whether you choose a tethered or vertical switch model, each one offers distinct advantages depending on the setup of your system.

For larger sump pits, tethered switches are the perfect hassle-free option. They automatically detect changes in water level and switch your pump on or off, so you don’t have to monitor it manually every day.

On the other hand, vertical switches are mounted on the pump and move up and down with the pump itself. They are a great choice for smaller sump pits. You can consider a top-mount float switch if you have a pedestal sump pump.

These switches also turn the pump on and off based on the water level but are integrated with the pump’s motor. Because of this, they can switch the pump on and off faster than tethered pumps.

2. Switch Material

Durability is key when selecting a sump pump switch, and it’s worth considering the materials used in its construction. That could make all the difference for long-term use.

You’ll want to steer clear of switches that might succumb to rust or damage after prolonged exposure to moisture.

For your sump pump to keep working effectively and reliably, choose robust switches crafted from corrosion-proof materials such as neoprene, PVC or high-grade plastic. That way, you can rest easy knowing that it won’t be affected by the dampness of its environment.

3. Compatibility With Your Sump Pump Model

Not all sump pump switches are made alike. Before buying a float switch, make sure it’s compatible with your specific model. This way, you can enjoy the peace of mind that your device will perform up to expectations and avoid costly damages.

If you have a pedestal or submersible sump pump, check the manufacturer’s specifications and recommendations to ensure that you get a switch that is compatible with your pump.

4. Power Cord Length

cast iron sump pumps

Your sump pump’s setup isn’t a simple plug-and-play like you might expect. Powering it up requires more thought. The key is selecting the best power cord length for your installation.

Go too short and say goodbye to an easy install, but keep that cord too long and all sorts of safety issues can come into play. Finding just the right size means properly positioning your sump pump, so choose wisely.

It’s probably best to have at least 9 feet of cord for a sump pump switch setup. This should provide enough flexibility for most installations without creating unnecessary risks or inconveniences. 

In general, power cords from 9 to 15 feet can offer better options for positioning your sump pump within a reasonable distance from the power outlet. That way, you can easily install the switch.

This will ensure your sump pump kicks on when the water rises and pumps out the basement water through the discharge pipe.

5. Dimensions of the Switch

You also need to think about the size and weight of the sump pump switch. The switch should not be too large, as it may not fit comfortably within the pit.

It should also not be too heavy, as it may cause the pump to tip over or become unstable. So, choosing a switch that’s the right size and weight for your sump pump setup is essential.

The dimensions of a sump pump float switch can vary depending on the specific model and manufacturer. You can find a variety of sizes for sump pump switches to suit your specific needs. 

In terms of length, options range from 2.25 inches to 8 inches. With regards to width, you can find electronic float switches with widths varying from 1.1 inches to 4 inches.

As for the height of the sump pump switch, you can select sizes ranging from 4.5 inches to 10.1 inches. 

Sump pump switches with higher dimensions are recommended for larger sump pits. Choose a sump pump switch with dimensions at the lower end of the range if you have a small sump basin.

6. Environmental Conditions

When choosing a sump pump float switch, the environmental circumstances in which it will be installed must be considered. The float switch must be weather-resistant and durable if the sump pit is exposed to extreme temperatures or humidity.

Coatings and materials used in the switch should be able to withstand harsh environmental conditions and perform optimally.

Also, understanding the maximum temperature range that the switch can handle is critical to prevent malfunctions or premature failure. Therefore, it is critical to choose a switch that is specifically designed for the environmental conditions of the installation.

How long does a sump pump switch last?

electronic switches

When it comes to a sump pump switch, the life of each is determined by an array of factors. From quality and conditions during operation to how often it is used, they all play their part in determining just how long your trusty sump pump switch will last you.

These hardworking components can survive anywhere between 5-10 years on average. However, the actual duration can vary considerably.

When installed correctly, a high-quality switch can last up to 10 years. A poorly made switch or improper installation can result in a shorter lifespan.

Additionally, if the sump pump operates frequently, the switch may wear out faster, resulting in eventual failure. In contrast, infrequent use may prolong the switch’s lifespan.

Operating conditions such as excessive humidity, water pressure, and debris accumulation can also determine the switch’s durability, ultimately affecting its lifespan.

How high should I set my sump pump float switch?

To determine the appropriate height for your sump pump float switch, it is important to consider the size of your sump pit and the power of your sump pump motor.

Ideally, the float switch should hang a few inches above the top of the motor. This ensures that the switch is triggered when the water level rises to the appropriate level in the pit. However, the exact height may vary depending on these factors.

Setting your sump pump float switch too low leads to energy waste and a worn-out pump, but setting it too high could mean serious flooding danger for your property. Ensure you get that sweet spot in between so everyone stays safe and sound.

How do you test a sump pump switch?

How do you test a sump pump switch

To test a sump pump switch, fill a 5-gallon bucket or other large container with water and slowly pour it into the pump basin.  If the rising water level activates the switch and the pump starts pumping the water out, your sump pump is working effectively. 

But, if the water level gets near the top of the pit and the pump doesn’t activate, you may have a bad switch. Ensure that the switch is properly wired and the float is free of debris and moves freely.

Safeguard Your Home with a Reliable Sump Pump Switch

Get serious protection for your home with a top-notch sump pump switch. Look for corrosion resistance, high heat tolerance, extra long power cord, powerful sensitivity and whisper-quiet operation to keep everything running smoothly and securely.

Superior’s model stands out as the top choice due to its robust build of corrosion-resistant materials and long power cord, all while running quietly and responding quickly with great sensitivity. Make sure you stay protected by investing in this reliable option that won’t let you down.
