12 volt water pump

I have a very similar situation where I use an RV water pump. I'm going to assume that you have a section of garden hose connected to the pump to allow you to travel from tree to tree? The problem that I see with the bilge pumps and the one linked to in post #2 is that they run continuously so when you shut off the flow at the end of the hose, what happens to the pump? The RV pumps have a built in pressure switch to alleviate this problem. I suppose a person could rig up their own pressure switch somewhere after the pump.

BTW - I do something similar to you with your gallon jugs except I use 5 gallon pails with a 1/8" hole drilled in the bottom of the sidewall. I'm not sure that 1 gallon of water would do that much for a small tree.

bilge pumps have loose fitting impellers ( no real pressure ) so shutting it off with a standard hose spray won't do any damage... or simply put the end of the hose back into the tractor tank and let it run ( use a small clip to hold the end from falling out of the tank)
