The answer to 'sprinkler system dying' is that a failing sprinkler system can be caused by a variety of issues, including broken pipes, malfunctioning valves, outdated components, or a damaged control system. Symptoms may include uneven water coverage, low water pressure, or areas of the lawn not receiving any water at all.
In many cases, the problem can be diagnosed and repaired by a DIY homeowner, but more complex issues may require the expertise of a professional landscaping or irrigation specialist. If you're unsure of the cause or don't feel comfortable making the repairs yourself, it's best to call in a pro to assess the system and provide a solution.
