Common Problems in an Irrigation System
Understanding the most common issues in an irrigation system will help you diagnose and fix them efficiently. Below are some frequent problems:

If some areas of your lawn receive more water than others, you may have:
- Misaligned or damaged sprinkler heads
- Clogged nozzles
- Incorrect system settings
Adjust sprinkler positioning and settings to ensure even coverage.
3. Sprinkler Heads Not Spraying Properly
Blocked or broken sprinkler heads can be a major problem. Inspect each head for dirt and debris, replacing or cleaning them as needed.
