Question
I'd like to get water to a garden i have on the far side of my property.  It's a 400' run from the house, and i'd like to be able to run 2 standard garden sprinklers.  It's a 15 ft elevation drop.  Eventually i'll bury the lines.  Can i go with flexible 3/4" poly hose?

Answer
Hey Paul, I would think if you are only going to hook up 2 heads(less than 6 gallons per minute) the 3/4" poly line would work just fine. But to play it safe, and just in case you might want to add on to the system later on, for a little more money, I would run a 1" poly line. Good luck and have a great day.
