Understanding Your Septic System

When to Schedule a Septic Inspection

Your septic system is an underground wastewater treatment structure. It typically includes a tank and a drain field, used for homes that are not connected to city sewer systems. Regular inspections and maintenance are essential to prevent issues such as backups, leaks, and system failures.

The Importance of Regular Inspections

Routine inspections are crucial for several reasons: 

  • Prevent costly repairs: Detecting issues early can prevent major, expensive repairs.
  • Ensure health safety: A malfunctioning system can lead to contamination of local water sources.
  • Increase lifespan: Regular maintenance can extend the life of your septic system.
  • Compliance: Local regulations may require regular septic inspections.

Routine Inspections

It’s generally recommended to schedule a septic inspection every three years. This schedule allows professionals to check for:

  • Tank levels
  • Leaks
  • Blockages
  • Structural integrity

Signs of System Trouble

Certain signs indicate immediate attention is needed: 

  • Slow drains: Might indicate a blockage or full tank.
  • Unpleasant odors: Could be a sign of leaks or backups.
  • Wet spots in the yard: May indicate drain field issues.

Before Buying or Selling a Home

Real estate transactions are a prime time to schedule an inspection. This ensures the system is functioning correctly and can prevent potential disputes or unexpected costs.

After Major Storms

Heavy rainfall or flooding can stress your septic system. Post-storm inspections ensure everything is intact and functioning correctly.

Increased Household Usage

A growing household means more wastewater. Septic systems designed for fewer people may need more frequent inspections to keep up with increased usage.

Seasonal Considerations
