The answer to 'why is my septic tank' is that a septic tank can experience various issues that require attention. Common causes include a blocked or clogged drain field, a full septic tank, tree root intrusion, and improper maintenance. Symptoms may include slow draining sinks, gurgling sounds, sewage odors, and standing water around the septic system.
In many cases, minor issues can be addressed through DIY maintenance like pumping the septic tank, clearing the drain field, or addressing tree root problems. However, more significant problems may require the expertise of a professional septic system technician to diagnose and repair the issue properly. It's important to address septic tank problems promptly to prevent further damage and costly repairs.
