The answer to 'sprinkler system has weeds' is that weeds in a sprinkler system are a common problem caused by cracks, gaps, or poor drainage in the system. Symptoms include weeds growing around sprinkler heads, reduced water pressure, and uneven water distribution. The solution may involve repairing the sprinkler system, improving drainage, and applying herbicide treatments.
For minor issues, homeowners can often address weeds in the sprinkler system themselves through simple maintenance and spot treatments. However, for more complex problems like broken pipes or faulty valves, it's best to call in a professional landscaping or irrigation technician to diagnose and fix the underlying issues.
