Keep up with the preventive maintenance you can do yourself. I see so many home owners that pay no mind to their sprinkler system until there's a major problem with it. Preventive maintenance is the best but the least practiced.
I have recently started a new blog,
http://sprinklerbuddy.com/blog/, if any of the pros on here would like to post a guest blog on the topic of lawn irrigation, contact my admin. Your welcome to include a link as well. Guest blogs must remain informative and not a sales pitch.
