Understanding How a Septic Tank Works
Before learning how often should you empty your septic tank, it helps to know how your system functions.
A septic system separates solids (sludge) from liquids (effluent). Over time, the sludge builds up. When it reaches a certain level, the system can no longer function properly, leading to backups, odors, drain clogs, and even total system failure.
This is why regular septic tank pump out services are essential.
