Unlike its competitors, the Little Giant 554550 has a non-flat plastic tank that improves overall efficiency. To put it simply, the gunk and slime that accumulates over time sit on a compartment, and is isolated from the float switch. This way, the switch is kept operational and free from any obstruction.
On that note, we should also mention that the tank is oil-resistant, meaning it can withstand damage upon exposure to oil.
In addition to the safety switch, the model also has an external high-level alarm that can be wired into almost any audio/visual or building management system. Thanks to the 20 feet of 3/8-inch tubing, the operator can connect an air handler shutdown or building automation system.
Lastly, the presence of a test switch makes it easier to test if the pump has been wired correctly, without pouring in water. In tandem with the 1/4 check valve, this feature will come especially handy when the pump needs to be completely emptied.
What Could’ve Been Better?
Since the pump is primarily designed to work with household appliances, it might not be the perfect option for draining large amounts of water. Also, we’d have appreciated the model a bit more if not for the float switch quality.

Why Did We Like It?
Having tried the Diversitech-22 Condensate Removal Pump, we wanted to test another unit from the brand when we came across the IQP-120. And we were glad to see that its performance is not too far either.
Firstly, the 1/30 horsepower motor runs on the minimum required speed to keep it serviceable for a longer span. Now we don’t mean that the speed is not sufficient for clearing the condensate, but what this feature does is that it keeps the motor from getting overworked. This also results in low heat generation, which enhances its durability. Apart from that, the stainless steel mounting tabs work just fine to hold the pump together.
An all-out feature is the unique self-cleaning mode, which reduces maintenance efforts. Upon sensing an excessive accumulation or inflow of unwanted particles, the pump uses condensate water to clean its interior. Furthermore, the 0.25-gallon transparent bottom tank allows you to keep a constant eye on the water level.
Here again, the light indicator system mounted on the top of the pump will assist you in keeping a check on the overall operation.
What Could’ve Been Better?
As much as we appreciate the clear bottom tank, we are equally concerned about its plastic construction. Since it’s not made with the most superior-grade plastic, you have to be extra careful to ensure that it doesn’t bump into any surface.

Buying Guide For The Best Condensate Pump
So what should you look for in an ideal condensate pump? Is it the power consumption, or is it the capacity of the motor?
We’re sure that several such questions may have popped into your mind while going through our extensive review. So, bear with us a bit more as we list out some of the most important factors to keep in mind while buying a condensate pump.
Voltage
One of the first things to consider is the voltage or the power required. While most residential condensate pumps can operate on the standard household current (115v or less), some high-performing units may require additional energy. In such cases, you can look out for power-saving features to bring down the electric bills.
Float Switch
The float switch is one of the key components that ensure the correct operation of a condensate pump. What it does is senses the level of water in the tank, and then ‘command’ the unit to start the drainage process. In that sense, it’s important to ensure a good quality float or angled design that reinforces durability.
Safety Switch
To be safe and user-friendly, many condensate pumps employ a safety switch that can be integrated into an alarm system or directly into the appliance. This way, it can automatically turn off the device in case of a power failure or pump malfunction.
Mount
In our opinion, it’s best to opt for a unit that can be mounted on the wall or placed on the floor. Unless you’re looking for a specialized pump with only a single appliance type, the dual installation option will give you room for future requirements. No matter the type, it’s better if the package includes all the related accessories.
Tank Size and Gallon Per Hour
Generally, most residential condensate pumps are equipped with 1/2-gallon tanks. However, you can opt for a bigger tank size in case of bigger appliances. Likewise, a gallon per hour (GPH) count of 120 or more is suitable for quick and regular drainage needs.
There are two main types of condensate pumps: peristaltic (also known as a tube pump) and centrifugal. Peristaltic pumps use a tubular system to move condensate, while centrifugal pumps use an impeller or electronic motor to force the condensate through the drainage pipe.
Noise levels vary, but many modern condensate pumps have sound-absorbing features to minimize noise. Review the product specifications to ensure the pump meets your desired noise level.
Some condensate pumps are designed specifically for commercial use. Make sure to verify the compatibility of the pump with your specific commercial appliance before installation.
Selecting the right size depends on your appliance’s condensation production rates and the required lift height. Always consult with the appliance manufacturer’s guidelines before making a purchase.
Condensate pumps typically come with detailed installation instructions. Make sure to follow the manual and local building codes when installing your pump. For complex installations, consider hiring a professional.
Yes, some condensate pumps are designed to handle condensation from multiple appliances simultaneously. Confirm the pump’s compatibility and capacity before purchasing.
Regularly inspect your condensate pump for blockages, kinks in the tubing, and any signs of wear or damage. Additionally, clean the reservoir, pump, and tubes periodically to ensure optimal performance.
If your pump is not functioning correctly, first inspect it for issues such as clogs, kinks, or leaks. If problems persist, consult the user manual or contact the manufacturer for assistance.
On average, a condensate pump should last for 5 to 10 years, depending on its quality, maintenance, and usage.
