I finally got my system wired up to a controller. 7 of my valves are on one side of the house and 3 more are on the opposite side. I mounted my controller direcly above the 7 on the side of the house. I only really need to power two of the other 3 valves. I did some quick measuring and it's about 80feet distance and I'd have to run at least 3 wires. I went and priced out 250 feet of 20ga wire and Are there any alternatives out there?
