Hello, in past I have helped couple guys install sprinkler systems, they all had there preferences as to what equipment they used and what kinda pipe they used. I am looking to go out on my own this year doing a few installs, and am looking for some more advice on what I should use and equipment I should purchase. I like rainbird so going to use them, I prefer poly pipe over PVC.. as here it gets cold early in the fall, poly will give some if it freezes.. The thing I am tore between is, get a piece equipment that can vib plow the pipe in, or use a trencher on like a walk behind skid steer, or both? What do you prefer and why? Thanks in advance!
