Mini-split condensate pump
Quiet, automatic drainage for indoor heads that can't run a gravity drain. Lifts condensate up and away, and hides inside the line-set cover.

About this condensate pump
A mini-split condensate pump moves the water your indoor head produces up and out whenever a gravity drain isn't possible. Every mini-split makes condensate as it cools, and most systems drain it downhill through a sloped hose. When the head sits below the drain exit, on an interior wall with no downhill path, or at the end of a long horizontal run, gravity alone won't clear the water — and that's exactly what this pump is for.
When you need a condensate pump
- The indoor head is mounted lower than the point where the drain leaves the building
- An interior-wall install with no downhill route to the outside
- Basement or below-grade rooms where the drain has to travel upward
- Long horizontal runs where a gravity slope can't be maintained
Not sure what lift rating your run needs? Our condensate pump sizing calculator computes the required head and flow from your vertical lift and horizontal run.
How it works
A float switch senses condensate collecting in the head's drain pan and switches the pump on, lifting the water through small-diameter tubing to your drain line — up to about 33 ft of head. A built-in safety switch shuts the unit off before the pan can overflow, so a clog never becomes a leak. The pump is small enough to tuck behind the head or inside a line-set cover, keeping the install clean. Confirm your head's drain-fitting size and refrigerant against your installation manual, and see our line-set install guide for routing the drain alongside the line set.
