Why it matters
The Knocokie 83939 Mini-Split Condensate Pump lifts condensate from a mini-split head when the drain line can't run downhill; its listing gives 38L/h of flow.
Small mini-split pumps fit inside the line-set cover or the head's trunk. Size the lift for the vertical rise plus some margin, and wire the safety switch, where it has one, to stop the system if the water can't drain.
The listing gives dimensions of 5.31 inL x 7.68 inW x 3.94 inH, a shipping or unit weight of 1.5 pounds and plastic construction.
