I'm looking to install a top of the line irrigation system on my own lawn. I have 2 acres of turf. I have a well with a 3hp pump. 28 gpm @ the pressure tank. I will be working with an irrigation company to pull the pipe and mark heads. Me and my employee's will be the laborers, installing heads, valves and doing grunt work. I'm looking for opinions on what are the best heads, valves and controlers. I can purchase all brands: Hunter, Toro, Rain bird, Irritroll ect.. Set me up!
