The answer to 'my irrigation installation looks bad' is that there are several common causes, such as improper installation, damaged pipes or sprinkler heads, and clogged or malfunctioning components. Symptoms may include uneven water coverage, pooling, or visible leaks. To address the issue, you'll need to inspect the system and identify the root cause.
If the problem is due to improper installation or minor repairs, you may be able to fix it yourself with some DIY troubleshooting and repair. However, for more complex issues like major leaks, damaged underground pipes, or problems with the irrigation controller, it's best to call in a professional landscaping or irrigation specialist. They have the expertise and equipment to properly diagnose and resolve the problem.
