Just imagine walking into your utility room and you see water splattered on the floor. This is a major possibility if the condensate pump is not working properly. Safety switches and long-lasting motors are just a few features of the condensate pumps which will turn off the HVAC system if a leak is detected.
For modern requirements, condensate pumps have also evolved. The mini split condensate pumps are designed for being convenient and get rid of the condensate without any complicated pipe structure.
Selecting the best mini split condensate pump can be a task more difficult than you can imagine. Therefore, we have made your job easier by listing some of the basic factors that will help in the process.
- Flow Rate: The flow rate of the mini splits is the primary consideration as it decides the amount of water that will be discharged through the pump in a minute. The unit of measurement is gallons per minute and the range should be between 0.15 gpm to 3 gpm.
- Noise Level: The noise level is an important factor as you want to have a conversation in the room and you would not like the other noise to disrupt the ongoing conversation. As the normal conversation is about 50 decibels, you should look for a mini split condensate pump that is around 20 decibels in the noise level.
- Lifting Height: Finally, the lifting height is determined by the maximum height at which the condensate pump is capable of functioning. For a mini split condensate pump, the maximum height should be between 20 feet and 35 feet.
More details and discussion on the features to look for when buying a mini split condensate pump are given in the “Buying Guide” given later in the article. In the following section, we have listed the best mini split condensate pumps with their notable features, advantages, and drawbacks. Check them all out and select your best one.

Things to Consider When Looking for a Mini Split Condensate Pump
There are many factors to consider while buying a mini-split condensate pump and you must understand what these factors are and how they affect the performance and align with your requirements. All the required factors are given below, check and then decide which one you can go for.
1. Flow Rate
The flow rate of the mini split condensate pumps are also referred to as the rate of the total volume discharged through the pump in a minute. The unit which is generally used to express this is gpm or gallons per minute. The mini splits do not require a very high power pump as most of the water is evaporated in the drain pipe.
But, for the extra water and to prevent the infiltration of insects or unconditioned air, the condensate pumps become inevitable. The ideal flow rate of the condensate pumps for mini splits should be between the range of 0.15 gpm and 3 gpm. This range of flow rate will get rid of the excess water and make sure that the mini splits can function properly.
2. Noise Level
It is normal for the mini split condensate pumps to make a little noise, but it should not be loud enough to distract from the conversation that is going on in the room. For this, we need to understand the noise level of different things. Firstly, total silence is rated at 0dB while whispers are near about 15dB. And normal conversation is rated at 50dB. It is recommended to go for those mini split condensate pumps that have noise levels around 20dB so that it does not overpower any conversation.
3. Lifting Height
The lifting height refers to the maximum height at which the condensate pump can pump. Now, there is a simple rule to install a mini split condensate pump for a room with a standard ceiling height. The rule says that pumps should be installed at the height of 6 feet above the ground. This enables the ceiling to be 4 feet to 6 feet above the pump. Now, for the proper functioning of the pump, for any air to be conditioned should be between the range of the lifting height should be between 20 feet to 35 feet.
4. Type of Pump
There are two considerations we need to keep in mind when discussing the types of mini split condensate pumps. Based on the design, there are two types of condensate pumps-dynamic or centrifugal pumps and positive displacement pumps. The first kind uses velocity and fluid momentum to create the pump pressure, they are the most common.
The second kind works on the principle of contracting and expanding the cavities through which the fluid passes. They offer a slow but steady flow with high pressure. Based on the application, there are two kinds: circulation and sump pumps. The former closes the cooling or heating system by returning the condensate from storage to the system for reuse, while the latter is installed in areas or compartments to get rid of the unwanted build-up.
When choosing the mini split condensate pump, always check the voltage requirement, and it is better to go for the one that is compatible with the voltage unit of the mini split air conditioner. If the pump does not receive the proper power required by it, the pump can damage the whole system and make it non-functional.
6. Tank Capacity
The tanks of the condensate pumps can usually hold water capacity ranging from 2 litres to 4 litres or 0.5 gallon to 1 gallon. There are many smaller units of these pumps that do not feature a tank, and it is installed directly on the drain pipe so that it can condense the water out of the pan.
Finally, you should check the warranty that the brand offers. The terms and conditions of the warranty can vary, so it is suggested to check them thoroughly. Most of the mini splits condensate pumps, however, come with a warranty and can last for 5 years to 10 years. For some products, you can register for a lifetime warranty within 60 days of installation.
Mini Split Condensate Pump FAQs
Ans: The smaller mini split evaporator does not need condensate pumps as the evaporator pan can drain out by gravitational force. But for that you need to make sure that the drainage system is proper.
Ans: The condensate pump should at least last for 3 months if not more.
Ans: On average, you can expect 5 gallons to 20 gallons of condensate each day by a mini split system.
Ans: The condensation pump uses 60 watts of electricity approximately. It is a low-power consuming device with simple functioning.
