When a sprinkler control valve quits working, a chain reaction can occur. The ground dries up, the grass turns brown and dies, and you wonder whats going on now? The best way to keep your lawn healthy and head off this problem is to do a manual check of your sprinklers once a week. When you find a problem you can correct it before any permanent damage occurs. I went on vacation and came home to an area of grass that was dead. I checked the valve and it wouldn’t come on automatically.
