    In my other threads one idea is to put a second manifold in the middle of where my lawn is going to go between my circular driveways, this is where the tap comes into the house. I think I could hire a plumber to do this in what it would save in me in other costs, even with the additional backflow cost. Plus it would be a heck of lot less work up front.

    This would mean though that i need to run 200+ feet of sprinkler wire.

    I am pretty sure I can use 18 gauge wire on the colored wires but might want to go 14 on the return. Here is my question.

    Can you purchase a single cable that contains a mix of gauges as described? I need one with 5 colors for the five valves that will go in there. If so can you recommend a place on the web to buy it from?

    Thanks

    I am guessing to do what I am looking for here, I will need to buy one 14-1 wire for the return and another 18-5 wire for the colors?

    I'm guessing by return you mean common, no need for it to be larger unless your are running more than one zone at a time.

    Yes common, when you say larger, than 18 or 14?

    I saying that if I were doing this I would run an 8 conductor wire out to the box of all the same size. I would also use a larger wire as cost of wire is nominal and this way you could add 2 circuits later. BTW I know very little about irrigation but quite bit about low voltage controls.

    Standard irrigation wire works for those distances. I would run 8 wire also in case a wire goes bad over the years. Also the 8 wire will stretch less being pulled(if your pulling instead of trenching) the distance discribed.
