Welcome to Island County Septic Training

Pumping vs Inspection

Like a car, your septic system needs regular maintenance to prevent costly repairs or replacement. Septic Pumping should not be confused with a Septic Inspection. Inspections are required by law every 1-3 years depending on the type of system you have (Island County Code 8.07D). A thorough inspection will determine if your tank should be pumped or needs repair. The goal of pumping is to remove the solids from your tank. Your tank should be pumped when it is 1/3rd full of solids. Take Septic 101 to learn how to  avoid costly repairs and extend the life of your septic system. If you have a conventional gravity or pressure system, take Septic 201 to find out how to inspect it yourself.
