Septic Inspections for Real Estate Transactions & More

Septic inspections are commonly required during real estate transactions, but they can also be helpful for homeowners who want to better understand the condition of their system.


You may need a septic inspection if:


  • You are buying a home with a septic system
  • You are selling a home and township regulations require an inspection
  • Your municipality requires septic system compliance
  • You want to verify the condition of an older septic system
  • You are experiencing drainage or septic performance issues
  • You want peace of mind before purchasing a property


Because septic systems are buried underground, an inspection is often the only way to determine whether the system is functioning properly before problems arise.

Who Needs a Septic Inspection?

What Is Included in a Septic Inspection?

A professional septic inspection helps verify the condition and functionality of your onsite sewage system. During an inspection, our technicians will:


  • Locate the septic tank and system components
  • Identify the size, layout, and condition of the system
  • Inspect tank components such as tees and baffles
  • Check for cracked pipes or structural damage
  • Measure sludge and scum levels
  • Evaluate system performance and drainage
  • Identify any visible signs of system failure


After the inspection, we provide documentation that can be used for township compliance or real estate transactions, along with recommendations if any maintenance or repairs are needed.

SEPTIC SYSTEM 101

Understanding How Your System Works

If you’ve never owned a home with a septic system before, it’s helpful to understand how the system works and why inspections are important. Most septic systems include three main components:


Septic Tank

Wastewater from the home flows into the septic tank, where solids settle to the bottom and form sludge while oils and grease float to the top. Natural bacteria begin breaking down the waste during this process.


Distribution System

Partially treated wastewater flows out of the septic tank through distribution pipes or a distribution box that directs the liquid evenly into the drainfield.


Drainfield (Absorption Area)

The drainfield is made up of soil and stone where natural bacteria complete the wastewater treatment process. The soil filters the water before it safely returns to the environment.



Over time, solid waste builds up in the tank and must be pumped out regularly, typically every 2–3 years, to prevent damage to the system. A septic inspection helps verify that each part of the system is functioning as it should.

Not all inspections are related to real estate transactions. Sometimes homeowners request a diagnostic inspection when something doesn’t seem quite right.


If your septic tank has recently been pumped but you are still experiencing problems, our team can perform a site visit or diagnostic inspection to identify the cause.


During a diagnostic inspection we may:


  • Check the tank and system connections
  • Inspect pipes, tees, and baffles
  • Measure scum and sludge layers
  • Evaluate distribution boxes or septic pumps
  • Assess the condition of the drainfield


This process helps determine whether the issue is related to the septic system itself or another plumbing problem within the home. Addressing septic issues early can help prevent system failure or costly repairs down the road.

  • How often should a septic system be inspected?

    Most septic systems should be inspected every 3–5 years during routine septic service, though inspections are often required when buying or selling a home.

  • Is a septic inspection required when selling a home?

    Many municipalities in Central Pennsylvania require septic inspections before a property transfer. Requirements vary by township, so it’s best to check local regulations.

  • What is a septic certification?

    A septic certification is a document stating that the onsite sewage system has been inspected and found to be functioning properly according to current standards.

  • Can the septic tank be pumped during the inspection?

    Yes. In most cases, septic pumping can be performed at the same time as the inspection if needed.

  • What happens if the system fails the inspection?

    If problems are found, our technicians will explain the issue and provide recommendations for repairs or improvements.

  • How long does a septic inspection take?

    Most inspections take 1–2 hours, depending on the type of system and accessibility of components.

  • Do all septic inspections require a hydraulic load test?

    No, not every septic inspection requires a hydraulic load test. These tests are typically only required when a property has been vacant for more than 7 days prior to the inspection. When a home has not been occupied, the septic system hasn’t been receiving normal water usage, so a hydraulic load test may be used to simulate typical household water flow and ensure the system and drainfield are functioning properly.


    If a hydraulic load test is required for your inspection, our technicians can perform the test and provide the necessary documentation for township compliance or real estate transactions.
