I tried the Mermaid but had issues with water flow. I have a 12K BTU with a March LC-3 pump. The Mermain Condensator seemed to decrease the flow quite a bit and thus I had issues with cooling the old AC unit.
And then I found the simple answer: Tom Aquatics Aqua Lifter—Dosing Pump
. It can lift up to 30 inches and sucks my drain pan dry. My issue is that I can not even drain to the bilge due to a rise in the tubing path. This at least gets it to the bilge. And all for $15!
