Septic Inspections: What to Expect & Why They're Important
A septic inspection is a professional evaluation of a septic system to ensure it is functioning properly, preventing leaks, blockages, and contamination. Inspections are typically required when buying/selling a home, experiencing drainage issues, or as part of routine maintenance.
Types of Septic Inspections
Visual (Basic) Inspection
- Performed during a home inspection or routine check-up.
- Involves checking:
✔ Water levels in the tank
✔ Drain field condition
✔ Signs of leaks or backups
🔍 Best for: Regular maintenance or real estate transactions.
Full (Comprehensive) Inspection
- A more detailed assessment of septic tank, pipes, baffles, and drain field.
- This type of inspection involves:
✔ Pumping the tank to inspect for cracks, leaks, or sludge buildup.
✔ Flow testing to check drainage efficiency.
✔ Dye testing (if needed) to detect leaks.
🔧 Best for: Older systems, suspected issues, or before major property renovations.
What Happens During a Septic Inspection?
🔹 Step 1: Initial Assessment
- The inspector asks about the system's history and recent issues.
- Check water levels in the tank for signs of backup.
🔹 Step 2: Tank Inspection
- Opens the septic tank lid to examine sludge and scum layers.
- Measures solids buildup—if it's over 30% of the tank capacity, pumping is required.
🔹 Step 3: Drain Field Evaluation
- Check for standing water, odors, or lush grass, which indicate drainage problems.
- May use a probe or camera inspection for underground pipes.
🔹 Step 4: System Testing
- Flow test: Runs water through the system to detect slow drainage.
- Dye test (optional): A colored dye is flushed to check for leaks.
🔹 Step 5: Reporting & Recommendations
- The inspector provides a detailed report on the system condition.
- Recommends repairs, pumping, or system replacement if needed.
Signs You Need a Septic Inspection
✔ Slow drains or gurgling pipes
✔ Sewage odors near drains or yard
✔ Soggy ground or standing water above the drain field
✔ Toilets backing up frequently
✔ It’s been over 3-5 years since the last inspection
How Often Should a Septic System Be Inspected?
- Residential Homes: Every 3-5 years (or annually if heavily used).
- Commercial Properties: Every 1-3 years, depending on system size.
