Residential Septic Inspections
Portland, OR — DEQ-Certified, Written Reports, Lender-Ready
Septic Inspections the Portland Metro Can Rely On
Lil’ Stinky has been inspecting residential septic systems across Clackamas, Multnomah, Washington, Marion, Columbia, and Yamhill counties for more than 25 years. Our inspectors are DEQ-certified and provide written inspection reports that satisfy lender and real estate transaction requirements throughout Oregon.
What separates Lil’ Stinky from a quick once-over inspection is simple: we pump the tank first—every time. You can’t properly inspect what you can’t see. Once the tank is emptied, we evaluate every major component, explain exactly what we found in plain English, and provide a written report you can actually rely on.
✔ Every Inspection Includes
- Complete septic tank pumping before inspection
- DEQ-certified septic inspectors
- Inspection of visible septic components
- Easy-to-understand written findings
- Reports accepted for Oregon real estate transactions
Three Situations That Require a Septic Inspection
Whether you’re buying a home, maintaining your system, or troubleshooting a problem, a professional inspection can save you thousands in unexpected repairs.
You’re Buying or Selling a Property
This is the most time-critical situation. In the Portland metro area, many homes outside city sewer service rely on septic systems—especially in Clackamas, Columbia, and Yamhill counties.
Routine Maintenance
Every Lil’ Stinky pump visit includes a visual inspection of accessible components. If you’d like a more complete evaluation—including a flow test and drain field assessment—we can perform that during your routine pumping appointment.
Septic systems rarely fail overnight. Routine inspections help identify small issues before they become expensive repairs.
Troubleshooting a Problem
Slow drains, sewage odors, pooling water, system alarms, or sewage backups aren’t “wait and see” situations. They’re signs your septic system is already under stress.
Lil’ Stinky will identify what’s causing the problem, explain your options in plain language, and recommend the right solution—without pressure or scare tactics.
What the Inspection Covers
Here is exactly what Lil’ Stinky evaluates:
We locate all access points and inspect tank walls for cracks, separations, or corrosion. Old concrete tanks in particular are prone to structural issues that look fine from the lid.
Failed baffles are one of the most common causes of drain field damage. We inspect both for condition and function — this is not optional.
We measure both layers and tell you how close the tank is to needing a pump if it hasn’t been done already.
We run water from the house while watching what enters the tank. This confirms the inlet line is clear and functioning.
If your system has a distribution box, we check it for cracks, damage, or uneven flow to the drain field laterals.
We look for surface saturation, sewage odors, vegetation anomalies, and any visible signs the field is being overloaded or failing.
You leave with a written report: every finding, every component condition, and specific next steps. Not vague language. Not a list of recommended repairs designed to sell you services. Straight answers.
Oregon DEQ and What It Means for Portland-Area Homeowners
Oregon regulates all onsite wastewater systems under OAR Chapter 340, Division 71. A few practical points:
Unpermitted changes to a septic system — rerouting lines, adding bathrooms without upsizing the tank, modifying the drain field — create compliance problems for every future owner. Lil' Stinky inspectors know Oregon DEQ standards and county-specific requirements across all six counties we serve. We flag compliance issues in our written reports so you know exactly what you're dealing with.
Lil' Stinky is a member of the National Onsite Wastewater Recycling Association (NOWRA), the Oregon Onsite Wastewater Association (O2WA), and operates in line with EPA SepticSmart guidelines. That's the professional network that keeps our team current on Oregon regulations.

Frequently Asked Questions
Does the inspection include pumping?
Yes — always. Pumping is required to properly inspect the interior. You get both in a single visit.
How long does an inspection take?
Usually two to three hours. More complex systems or difficult access takes longer. We give you a realistic time estimate upfront.
What if the system fails inspection?
We give you a written report that explains what failed, why, and what your options are. Many common failures — damaged baffles, blocked inlet lines, minor cracks — are repairable without replacing the whole system. If you’re in a real estate transaction, the report gives you documented grounds to negotiate.
Do you flag non-compliant conditions?
Yes. Older systems especially may have components that don’t meet current Oregon DEQ standards. We note these in the report and explain whether it creates an immediate compliance obligation or only becomes an issue upon future modification.
The seller says the system is ‘fine.’ Do I still need an inspection?
Yes. The seller’s opinion of the system’s condition has no legal standing and zero diagnostic value. A written inspection report from a DEQ-certified provider does. Get it done.
