Advance the cable until you feel resistance from the clog. Keep trees and large shrubs planted at least
Ground settling causes sections of the pipe to sink, creating a low spot (belly).
This is the most common scenario. Septic systems rely on bacteria to break down solids. However, the use of harsh antibacterial cleaners, excessive water usage, or flushing non-biodegradable items (often euphemistically labeled "flushable" wipes) can overwhelm the tank's biology. When the tank fills with sludge faster than it can decompose, solids migrate into the outlet pipe and clog the drain field.
Implementing strict preventative habits protects your system from future failures.
