The answer to 'why is my irrigation system erosion' is that irrigation systems can cause erosion due to improper installation, damaged components, or excessive water pressure. Symptoms of irrigation system erosion include visible channels, sinkholes, or wet spots in the lawn. Common causes include sprinklers aimed improperly, broken pipes, or insufficient drainage.
To fix irrigation system erosion, you may need to adjust sprinkler heads, replace damaged pipes, or improve the drainage system. Simple DIY fixes like adjusting sprinklers or filling in small holes are often possible. However, for more complex issues like major pipe leaks or drainage problems, it's best to call a professional irrigation technician to assess and repair the system.
