Septic System Plumbing Diagnosis

What causes a septic system to back up?
Backups on a septic system come from either the building side or the tank and drain field side. Afford-A-Rooter checks the building side first, the drain lines that carry wastewater from your fixtures out to the tank, since a break, root intrusion, or blockage there can look identical to a full tank. If the building-side lines are clear and the tank needs cleaning, that work goes to our sister company.
- Slow drains at multiple fixtures can mean a blocked line before the tank
- Root intrusion into older clay or cast iron lines is common in established neighborhoods
- A tank that has not been serviced in years is more likely to be the actual cause
Signs to check the septic system
- Multiple drains in the house running slow at once
- Sewage odor near the yard or drain field
- Gurgling from toilets or floor drains
- Standing water over the drain field
