The rust-proof half-gallon tank is composed of sturdy ABS plastic. Thermal overload protection is included in the 6-foot power cord of the condensate pump. You have the option of placing the condensate pump on a flat surface or mounting it on the wall.

The 554421 Condensate Pump is one of the most dependable and high-performing pumps from the company, and it’s perfect for intermittent usage. Its small size allows it to fit into even the tiniest of areas. When it’s time to change the pump after a few years, you should be able to do it yourself in minutes. Though it appears to be a little light and fragile in comparison to other pumps, its endurance may surprise you. If you’re searching for a low-cost solution with long-term dependability, we think this condensate pump is a great choice.

To be honest, the previous Little Giant pumps’ greater performance persuaded us to attempt a third unit. The 554421 Condensate Pump doesn’t make any extravagant claims, but it does a good job of delivering its promise. It’s also appropriate for heavy-duty applications because of its 80 GPH flow capacity.

Despite the fact that the plastic body does not appear to be extremely substantial, the ABS plastic substance makes it durable enough to sustain heavy use. Its powerful engine is thermally insulated and can withstand temperatures of up to 140 degrees Fahrenheit.

Diversitech Corporation IQP-120

best condensate pumps
Diversitech Corporation IQP-120 (Reference:

Pros & Cons

  • Silicone rubber feet for better stability
  • Vertical installation
  • Performs on standard household current
  • Four inlet holes
  • The plastic tank is prone to cracks and damage


Motor 1/30 horsepower
Tank capacity 0.25-gallon
Material Plastic


General Descriptions

To begin with, the 1/30 horsepower motor works at the lowest possible speed to keep it functional for a longer period. This feature does not suggest that the speed is insufficient for cleaning the condensate; rather, it prevents the motor from becoming overworked. This also means that it produces less heat, which increases its durability. Apart from that, the stainless steel mounting tabs keep the pump together well.

The unique self-cleaning mode, which lowers maintenance requirements, is a standout feature. When the pump detects an excessive buildup or influx of undesirable particles, it cleans its inside with condensate water. Additionally, the 0.25-gallon clear bottom tank allows you to monitor the water level at all times.

The light indication system on the top of the pump will let you keep an eye on the general functioning once again.

We like the glass bottom tank, but we’re a little concerned about the plastic construction. Because it’s not constructed of the highest quality plastic, you’ll have to be extra careful not to bang it into anything.

FUJIWARA Condensate Pump

best condensate pumps
FUJIWARA Condensate Pump (Reference:

Pros & Cons

  • Lightweight and slim design
  • 3-watt power consumption
  • Damage-free wall installation
  • Practically noise-free
  • Needs a longer drain line at extra cost


Flow rate 40 GPH
operating range 100-220v
inner diameter ½ inch


General Descriptions

This fully automated machine is the ideal combination of efficiency, dependability, and convenience at a price that won’t break the bank. Furthermore, it runs on a low-voltage source, which means it won’t raise your power cost.

First and foremost, the tiny and quirky design piqued our interest. And, while appearances should be the last thing on your mind when purchasing a condensate pump, we don’t mind its appealing design. So you get bonus points for it!

When it comes to performance, the completely autonomous operation is, without a doubt, the best. In the event of a rapid float displacement, the probe induction technique also avoids the possibility of anomalous drainage.

However, it may be useful to know that when the incoming flow exceeds the pump’s specified flow rate, i.e. 40 GPH, a small bottom hole on the unit will empty water. This system guards against a short circuit in the motor, ensuring its safety.

Not only can the pump be used to remove condensate from a variety of appliances, but its 100-220v working range adds to its versatility. Furthermore, the 32-foot lift should be perfect for resolving maximum condensate issues. It’s also a fantastic choice for usage in bedrooms because of the low sound output.

Only wall-mounting is supported by the Fujiwara Condensate Pump, and all necessary components are included in the package.

In comparison to the 32-foot lift, we thought the drain hose that came with the equipment was too short. As a result, we recommend buying a separate hose, preferably one that is approximately 100 feet long and has a 1/2-inch inner diameter. This will cost you more money, but it will ensure that your business runs well.

General Descriptions

This unit is no exception to the brand’s reputation for producing high-quality water pumps. Its’ easy-to-follow instructions and familiar design appeal to both novice and experienced users.

This model, like the Little Giant VCMX 20ULST, is designed to meet the various needs of home use. In that regard, the familiarity of design and application struck us. It’ll be simple to figure out how to operate a replacement pump if you’re seeking one.

The pump is useful for different appliances such as furnaces and dehumidifiers, however, we utilized it to remove condensate from our air conditioners. In the event of a power outage, an incorporated safety switch automatically turns off the pump. The high-impact thermoplastic tank can withstand a few blows with ease.

It also has a dual mount mechanism that allows for maximum installation versatility. It may be mounted on the wall or be placed on the floor, depending on your preference.

The WaterAce WACND Condensate Pump, with three intake holes and a 3/8-inch output, appears to be a no-nonsense pump that remains true to its mission.

Because this condensate pump isn’t the quietest on the market, you’ll probably want to keep it in the basement. We would have preferred a quieter pump for a pump aimed at household usage. We’re also not sure if it can deal with high-temperature condensate from a steam generator.

It has a strong build that can survive daily usage and is equipped with a slew of user-friendly features. This device may easily meet your needs if you’re looking for efficiency on a budget.

The Mars 21780 Condensate Pump accomplishes a number of things to increase its sturdiness. To begin with, the dip-proof housing design allows for better air circulation and avoids water droplets from forming on the motor. As a result, the motor can work to its maximum capacity.

The motor uses sealed ball bearings rather than the more conventional sleeve bushings to ensure silent operation. We were very happy with the float switch’s quality, especially after dealing with a handful of subpar switches previously.

This type, like the Little Giant Condensate Removal Pump, has a 1/2-gallon water tank and can drain up to 125 GPH. The built-in 250v safety switch can also be connected to a high-level alarm system or used to shut off equipment directly.

Finally, without disconnecting the condensate line, the fast-release silicone check valve allows for quick and easy service. The Mars 21780 Condensate Pump is one of the most user-friendly machines on the market because of this as well as its ease of installation.

Despite its efficiency for the price, the device is not without problems. The plastic tab that connects a sliding lock to the base is of special concern to us. Because the lock secures the hose and check valve, any damage to the tab renders the unit inoperable.

General Descriptions

Beckett is a well-known brand in the medium-sized condensate pump sector, and the CB151UL earns a spot on our list. Its innovative lightweight design is intended to improve overall performance and longevity. If you value safety and dependability above all else, this product could be the one for you.

In the food market, Beckett is a well-known name. This pump has a 115-volt motor with a 120-gallon-per-hour flow rate. Even somewhat bigger particles will easily pass through.

When it comes to the brand’s design, the innovative airflow mechanism does an excellent job of reducing heat generation and operational noise. Furthermore, the dual-float type design ensures that pump operations are not required frequently, extending the product’s service life.

The pump is simple to install and will perform effectively for a long time once it is turned on. Because the plastic tank that protects the pump is delicate and vulnerable to harm if struck or dropped, you must be careful where you place it.

The Beckett condensate pump is slightly more expensive than some of its Little Giant contemporaries, but it is a device that should last a long time if installed correctly.

The device has a 120 GPH flow rate and is powered by a powerful 115v motor. Furthermore, it is capable of passing medium-sized particles without causing any discomfort to the user. But it doesn’t stop there in terms of user-friendliness. The installation is straightforward and it can be installed from both sides. It comes with a 6-foot long power wire.

Overall, the Beckett CB151UL prioritizes both performance and safety. If premium cost isn’t a concern, this high-performing item might be a good value.

We were a little disappointed by the heavy plastic odor, especially after the OEM clearance. Furthermore, the float switch is prone to become stuck, and there are no clear instructions for how to set it up. To minimize any undesired spills, we recommend inspecting the switch before installing the device.

Little Giant VCMX-20ULST 554550 VCMX Series Automatic Condensate Removal Pump

best condensate pumps
Little Giant VCMX-20ULST 554550 VCMX Series Automatic Condensate Removal Pump (Reference:

Pros & Cons

  • Three inlets and a 6-feet power cord
  • 84 GPH and 1-feet lift
  • Includes wall mounting bracket
  • The Angled float switch doesn’t touch the tank’s bottom
  • 4 rubber feet reduce noise and vibration
  • Delicate float switch
  • May not be adaptable for draining a large amount of water


Operating 115v
Range 1/30hp
Material Non-flat plastic
Capacity 84GPH


General Descriptions

Another dependable Little Giant device is this pump. It provides 115 volts and 1/30 horsepower, making it an excellent choice for home appliances. At a one-foot raise, it has a powerful flow of 84 gallons per hour. It may be mounted on the wall or placed on the floor, with its rubber feet dampening vibrations. The VCMX 20ULST 554550 is a cost-effective and efficient condensate pump with a strong engine for forceful water discharge. It’s also appropriate for domestic usage because of its lower footprint.

This one is powered by a strong 1/30 Horsepower motor with an overload prevention system. Its cooling architecture, on the other hand, ensures a longer service life. One possible difficulty with this pump is that the reservoir isn’t clear enough to examine quickly, so you’ll have to trust that it’s operating properly.

We feel this pump is extremely cheaply priced, considering it has a larger lift capacity and better transfer rates than some other condensate pumps. This condensate pump should endure for a long time if you don’t use it for appliances that pump big volumes of water. The Little Giant 554550, unlike its competitors, features a non-flat plastic tank, which enhances overall efficiency. Simply put, the muck and slime that builds up over time collect in a compartment that is separate from the float switch. The switch will remain active and unobstructed in this manner.

On that note, it’s worth mentioning that the tank is oil-resistant, which means it can tolerate damage from oil. The model also contains a high-level external alarm that can be plugged into practically any audio/visual or building control system, in addition to the safety switch. The operator can link an air handler shutdown or building automation system to the 20 feet of the 3/8-inch tube.

Finally, the availability of a test switch makes it easy to determine if the pump has been properly wired without the use of water. This function, in combination with the 1/4 check valve, will be especially useful when the pump has to be entirely emptied.

Because the pump is intended for use with domestic appliances, it may not be the best choice for draining huge volumes of water. Also, if not for the poor quality of the float switch, we would have given the model a higher rating.
