Septic System Inspections for Tigard Homes
A septic inspection tells you whether the system under a Tigard property is working, what shape the tank and drain field are in, and what repairs might be coming. It is one of the most useful reports you can have before buying or selling a home that is not on city sewer.
Request a call and a septic company that inspects systems in Tigard and King City, Durham, Tualatin will explain what their inspection includes and when they can get out.
Inside a septic inspection
Inspectors look at the system from the house to the drain field. They confirm where the main line leaves the house, open the tank to check its condition and levels, and inspect the baffles and any effluent filter. Outside, they walk the drain field and look for soggy ground, lush grass stripes or odors. Some inspections add a camera run through the lines or a hydraulic load test that sends a measured amount of water through the system.
Choosing the right level of inspection
Not every inspection is the same. Some lenders or buyers only need a basic functional check, while others want the tank pumped and inspected empty, plus a look at the distribution box and drain field. If the system is old, has no records, or the home has been vacant, ask for the more complete option. It costs more up front but gives a far clearer answer.
When to get a septic inspection
Get an inspection before buying a home with a septic system, before listing your own, and when you refinance if the lender asks for one. It also makes sense every few years as part of routine care. Other good times are after a major backup, before adding a bedroom or bathroom, or when the home has been empty a long time. Many owners schedule an inspection at the same time as pumping to save a trip.
Why the written report matters
The report is what you, your lender and the other party in a sale will rely on. It should describe the system in plain terms, note its condition, and separate urgent problems from routine maintenance. A report with measurements and photos is far more useful than a single line saying the system passed.
Getting the property ready
Clear access to the tank lid and drain field, unlock gates and keep pets inside. Let the inspector know about any past backups, alarms or repairs. If the home is vacant, ask whether water should be run ahead of time. the Washington County health department may have records for the system that the inspector can use, so it helps to request them early.
Questions to ask a septic inspector
Ask what their inspection includes, whether the tank will be opened, and whether pumping is part of it. Ask if they probe or test the drain field, how long the inspection takes and when you will get the report. Confirm licensing or certification required where you live and ask for a sample report so you know what to expect.
When to inspect even without a sale in Tigard
An inspection in Tigard makes sense after buying a home without records, after a backup or before an addition. It tells you the size, layout and condition of the system. Knowing that ahead of time helps you budget for pumping or repairs instead of being surprised by them.

Septic Inspection questions in Tigard

- Should the tank be pumped before an inspection?
- Many inspectors prefer to see the tank before and during pumping so they can judge how the system has been working. Ask the inspector what they want rather than pumping on your own beforehand.
- Who pays for a septic inspection during a sale?
