I have done a few irrigation installs and have done some maintenance but I am by no means a expert. What i do know is enough to get me into trouble but you have to start learning somewhere, right? Well I am going to be expanding into another town next year hopefully and most of the lawns there are irrigated. What I have noticed is they water everyday even when it rains. All these places are on city water so they have to be spending a bundle on water. I was going to sell them on being able to save them so much money per month if they would go with us. I figured I would install the Hunter(I am drawing a blank on the name of it right now) option of measuring rain, water and all that to control there water as well as cut it back to maybe three days a week instead of 7. What I am wondering is how much money could I save them by doing this. I know it is going to depend on the size of the lawn, what they are running as far as heads and all that. I am just looking for a general ballpark.
