      Comments about Par Max 1, Miniature Automatic Demand Pump:

      The cooler in my boat drained directly into the bilge. I prefer to keep any water I can from entering into the bilge. I'm using this pump to lift the cooler water to my sink drain above the boat's water line to drain outside. The pump handles the load quite nicely. It works as advertised. I'm very pleased.
