The answer to 'drainage system disease' is that a poorly functioning drainage system can be caused by several issues, including clogged pipes, damaged components, or improper installation. Symptoms may include standing water, soggy soil, and even foundation damage. To address this, you'll first need to identify the root cause, which may require inspecting the system or consulting a professional landscaper.
For minor clogs or issues, homeowners may be able to perform some basic DIY maintenance, such as clearing debris from grates and cleaning out pipes. However, for more complex problems like structural damage or extensive blockages, it's best to call in a professional landscaping service that can properly diagnose and repair the system.
