Troubleshooting Problems

Here are steps to troubleshoot your standard gravity septic system:

Open the septic tank lid and check the water level.
This is the first and most important indicator of where a problem may exist.

• • Take photos of the inside of the tank and water level this may help a septic technician diagnose the issue by phone.

If the water level is normal:
The issue is likely in the plumbing line inside the house or in the pipe running from the house to the tank.

1. • • This could be a simple clog or blockage.
     • A sewer snake may be able to clear the line.
     • If the pipe has collapsed or deteriorated, it will need to be repaired or replaced.
2.  

If the water level is high:
The problem is likely beyond the tank.

Possible causes include:

• • • Excess sludge buildup in the tank
    • A clogged outlet line leaving the tank
    • Drainfield (drain field) failure due to:
      • Soil saturation
      • Crushed lines from heavy vehicles
      • Shifting soil
      • Root intrusion

Inspect the line leading to the drainfield:
Using a sewer snake to clear the outlet line and if the snake pulls back mud, this may indicate the line is damaged or broken.

Observe the tank during pumping:
If a large amount of wastewater quickly flows back into the tank after pumping, it is a strong sign that the drainfield is saturated or failing.
