I've been running one of
these on my reefer 170 connected to a JBJ ATO. My container is mounted on the floor 32 inches from the pump and the pump is 30 inches off the floor and it has been working great pulling the water that far. Its also very noisy when the container runs dry, which is usually in the middle of the night but at least it lets me know I need to swap jugs (tank is in the bedroom). A little soldering is involved and its not sleek and cool looking but it works. On my larger system I use an old MJ 1200 also connected to a JBJ unit only it is pushing water rather pulling and it works great as well. I'm not into super high tech ATO units. Give me a good solid unit with a mecahnical float switch and a cheap pump and I'm happy.
