When it comes to owning a home with a septic system, regular inspections aren’t just a good idea — they’re essential for preventing costly repairs and keeping your wastewater system running smoothly. Whether you’re buying a new home, selling your property or simply performing routine maintenance, a septic inspection offers peace of mind and valuable insight into the health of your system.
But what exactly happens during a septic inspection?
In this guide, we’ll walk you through the process step-by-step, explain what inspectors look for and cover the different tools and techniques used to make sure your septic system is in top condition.
Why Inspections Are Important
Your septic system works quietly in the background, handling all wastewater from your sinks, showers, toilets and appliances. Over time, components can wear down, blockages can form and drainfields can become saturated — all of which may lead to septic system failure if left unchecked.

A septic inspection helps:
- Detect minor issues before they become major repairs.
- Confirm your system is functioning efficiently.
- Ensure compliance with local health codes and regulations.
- Provide a clear status report for real estate transactions.
In short, a septic inspection is an investment in your property’s safety, value and environmental health.
Two Types of Septic Inspections
Before we dive into the process, it’s helpful to know that there are generally two types of inspections:
1. Visual Inspection – Often performed during a home sale, this type of inspection involves a general check of the visible components of the system and a simple water test to ensure basic functionality.
2. Full Inspection – A more in-depth evaluation that includes opening the septic tank, measuring sludge and scum levels, checking all mechanical parts and assessing the drainfield’s condition.
The level of inspection you need depends on your situation — but for homeowners committed to long-term care, a full inspection is usually best.
These Are the Most Common Steps in a Septic Inspection
During a standard septic inspection, your technician will go through a series of steps to assess the health and functionality of your system. Here’s what’s typically included:
1. Locating and Accessing the Septic System
The first step is to locate all components of your septic system — including the septic tank, drainfield and distribution box. If your access lids aren’t exposed, the inspector may need to dig them up. This ensures that each part of the system can be properly examined.
2. Visual Examination of Key Components
A thorough visual inspection includes checking:
- Septic Tank – The inspector examines the tank for cracks, leaks, corrosion and overall structural integrity. They’ll also look for signs of improper maintenance or overloading.
- Drainfield – The drainfield’s surface is checked for standing water, soggy patches or strong odors, which could indicate a problem with wastewater absorption.
- Distribution Box – This component ensures wastewater is evenly distributed to the drainfield. Inspectors check for blockages, damage or uneven flow.
- Piping – Pipes are inspected for breaks, clogs or root intrusion that could restrict flow.
- Indoor Plumbing – Toilets, sinks and drains are tested to confirm water is flowing freely into the system.
- Records and Compliance – The inspector may review past maintenance records and make sure your system complies with local health regulations.
3. Functional Testing
Once the visual inspection is complete, the inspector will run water through the system by flushing toilets and running faucets. This helps check for slow drainage, backups or unusual noises that could indicate a clog or blockage.
4. Advanced Inspection Techniques
In some cases, your inspector may use specialized tools to get a more accurate picture of your septic system’s condition. These may include:
- Camera Inspection – A small video camera is inserted into the pipes to check for cracks, corrosion or obstructions without the need for excavation.
- Sludge Judge Test – This test measures the thickness of the sludge and scum layers inside your septic tank. If levels are too high, it’s a sign that your tank needs to be pumped.
- Probe Test – A soil probe is used in the drainfield to evaluate how well the soil is absorbing and filtering wastewater.
Common Issues Found During an Inspection
A septic inspection may uncover issues such as:
- Overfull septic tanks
- Clogged or damaged pipes
- Saturated drainfields
- Root intrusion
- Improper system sizing
- Failing baffles or filters
The sooner these problems are caught, the easier — and often less expensive — they are to fix.
How to Prepare for a Septic Inspection
You can make the inspection process smoother by:
- Providing maintenance and pumping records.
- Clearing the area around the septic tank and drainfield.
- Ensuring access lids are visible or easy to uncover.
- Avoiding heavy water usage right before the inspection.
How Often Should You Schedule an Inspection?
For most households, it’s recommended to have a septic inspection every three to five years, or more frequently if your system experiences heavy water usage. If you’re buying or selling a property, an inspection should be completed as part of the transaction process.
What Happens After the Inspection?
Once the inspection is complete, your technician will provide a detailed report outlining the condition of your septic system, any repairs needed and recommendations for future maintenance. If repairs are necessary, addressing them quickly will help prevent further damage and more expensive fixes down the line.
The Importance of Proactive Septic System Management
A septic inspection is more than just a quick check — it’s a comprehensive evaluation of your system’s health.
By understanding what happens during the process, you can be better prepared, ensure your septic system remains in peak condition and avoid unexpected (and costly) surprises.
