What is a Septic Inspection?

A septic inspection involves a thorough check of the septic system, including the tank, drainfield, and other components. Inspectors look for signs of wear and tear, leaks, and other problems that could lead to costly repairs or replacements.

Why It’s Critical Before Buying a Property

When you’re buying a property, the last thing you want is to discover unexpected issues after the purchase. A septic inspection provides peace of mind and ensures that the system is functioning correctly. It can reveal potential problems like:

  • Tank damage or leaks
  • Drainfield failures
  • Clogged pipes
  • Inadequate system size

Inspection Components: What to Expect

Tank Inspection

The tank is the heart of the septic system. Inspectors will:

  1. Measure the scum and sludge layers
  2. Check for leaks and cracks
  3. Ensure the tank is the proper size for the household

Drainfield Examination

The drainfield disperses wastewater into the soil. An inspection will:

  1. Assess the soil absorption capacity
  2. Look for standing water which indicates poor drainage
  3. Verify the field’s size matches the tank’s capacity

System Components

Other parts of the system include:

  1. Pipes and pumps: Checked for leaks or damage
  2. Baffles and filters: Ensure they are clean and functioning correctly
  3. Septic alarms: Verify these are operational to alert you of issues
