Its thermally protected motor ensures durability and ultra-silent operation at 19 dB. The pump’s Hall sensing float switch guarantees automatic activation and long-lasting service life.
With anti-vibration Velcro straps, the pump is easy to install in tight spaces such as line set covers and ceiling cavities. It includes a removable tank and filter for straightforward maintenance.
Little Giant EC-1-DV Mini Condensate Pump
The Little Giant EC-1-DV is a reliable choice for mini split or ductless air conditioners, with a flow rate of 2.7 GPH and a maximum head of 33 feet. It operates quietly at 21 dB, aided by a noise reducer included with the unit.
It supports multi-size hose adapters for compatibility with various drain connections and operates on 110-240 volts with a power consumption of 18 watts.
While its flow capacity is lower than some competitors, this pump is effective for light-duty applications or smaller capacity mini split systems.
Buying Guide: How to Choose the Best Pump for Mini Split HVAC Systems
Flow Rate and Pumping Capacity
Flow rate, typically measured in gallons per hour (GPH), determines how quickly the pump can remove condensation. Select a pump with a flow capacity suitable for your mini split system size and expected condensate volume. Pumps ranging from 9 to 11 GPH accommodate most residential mini split units.
Maximum Head (Lifting Capacity)
The maximum head indicates the highest vertical lift the pump can achieve when expelling water. For installations with longer vertical runs or complex routing, opting for a pump with a higher max head—over 50 feet or more—is essential to ensure reliable drainage without strain.
Noise Level
Since condensate pumps often operate near living spaces, quiet operation is critical. Most modern mini split pumps run below 20 decibels (dB), which is comparable to a whisper. If noise sensitivity is a concern, prioritize pumps rated 18 dB or lower.
Voltage Compatibility and Power Efficiency
Confirm the pump’s voltage requirements match your available power supply, typically 110V-240V in residential settings. Energy-efficient pumps with low standby and operating power consumption help reduce utility costs and environmental impact.
Installation and Mounting Options
Look for pumps with flexible installation features such as anti-vibration mounts, compact designs, and compatibility with standard tubing sizes. Wall-mounted or line-set cover mounting capabilities simplify integration into existing HVAC setups and minimize space usage.
Automatic Safety Features
Pumps equipped with float switches and safety shutoffs offer protection against water overflow by automatically stopping the connected HVAC equipment or triggering alarms. These features enhance reliability and prevent water damage.
Maintenance and Durability
Removable tanks and easy-to-clean filters improve maintenance convenience. Thermal protection on motors and durable construction extend pump lifespan, minimizing the need for replacement or repairs.
Compatibility with HVAC Equipment
Ensure the chosen pump suits your mini split system’s specifications and intended condensate volumes. Pumps designed for HVAC, dehumidifiers, and furnaces are generally versatile and reliable for mini split condensate removal.
