Broken Sprinkler Heads
Before running your sprinkler system, perform a visual inspection for broken heads. Since most irrigation systems are scheduled to run in the wee morning hours, damaged sprinkler heads often go unnoticed. In fact, many homeowners aren’t aware of the issue until they get an outrageous water bill in the mail.
To replace damaged heads, simply unscrew the head(also called a stem) and bring it to your local hardware store for a replacement.
Misaligned Spray Patterns
Systematically run each zone, making note of obstructed and misaligned spray patterns. Prevent dry, dead patches in your landscaping by trimming back any shrubs that interfere with spray heads. Adjust spray heads to avoid excessive over-spray on sidewalks, driveways, and areas that are prone to rot(such as window seals).
