Hi I am wondering about setting a siphon out to fill a dugout before winter, it will be coming about 400 feet and all downhill from a different dugout. I have about a million gallons to move. Was wondering if anyone had experience with this type of thing and what size of hose is best. We have pumped it with a 6 inch honda pump a few times but gets to be a pain to have to go and fuel it up a couple times a day. Plus the expense of the pump wear and tear and the fuel. She's all down hill anyways.
