Has anyone tried putting a fill up hole on the top of the 3.5 Gallon Waterers? I wanted to know how well it worked and is it easier than taking the bottom off and filling it?
It will just drain out as fast as you put it in---or close because it will be getting air in the top. Example-----fill your kitchen sink with water-----lay a glass in the water on its side. Now keeping the drinking end under water stand the glass up---upside down-----now lift the glass----it stays full of water until the drinking rim gets out the water----then it dumps. Now get a piece of pipe with both ends open----stand it in the sink water and draw it up towards the facet turn the water on and try to fill it----it want fill just like drilling a hole in this waterer in the top----all the water will go out.
