I am not a stranger to irrigation. Most of my experience is in repairs but I do have a decent amount of experience in installs. But I have never designed a system. I do have a design that I am working on for my parents house and have done alot of research, but I also know that its my first design and that stuff does not always work as planned. I am kinda wanting to go with a manifold type system as opposed to having lots of small valve boxes all over the place. What do you all prefer and why so. I do understand that both have their places but what do you prefer and why.
