Buying Guide
When selecting a condensate pump for your mini split system, several critical factors determine the best choice for your specific installation. Pumping capacity is measured in gallons per hour (GPH) and should match or exceed your system’s condensate production rate. Most residential mini splits produce 1-3 gallons per hour during peak operation.
Maximum head height represents the vertical distance the pump can lift water. Measure from the pump location to the drain outlet, adding extra capacity for horizontal runs and fittings. A 30-40 foot capacity handles most residential installations, while commercial applications may require 60+ feet.
Noise levels are crucial for indoor installations. Look for pumps rated below 25 dB for living spaces. Units operating at 19-21 dB are virtually silent and ideal for bedrooms or quiet areas. Consider the pump’s location relative to occupied spaces when evaluating noise requirements.
Safety features prevent water damage through automatic shutoffs and alarm connections. High-level switches detect rising water and can shut down the AC unit or trigger alarms. This protection is essential for unattended operation and system reliability.
Installation flexibility affects placement options and ease of service. Compact designs fit within line set covers or ceiling spaces, while removable tanks enable easy maintenance. Consider access requirements for cleaning and filter replacement when planning installation.
Voltage compatibility ensures proper electrical connection. Universal voltage pumps (100-240V) offer greater installation flexibility, while fixed voltage units may require specific electrical configurations. Verify your system’s electrical requirements before selection.
Connection sizes must match your drainage system. Standard inlet sizes range from 3/8″ to 5/8″, while outlets typically accommodate 1/4″ to 3/8″ tubing. Ensure included adapters or purchase separately to achieve proper connections.
