You should periodically inspect your home's septic system. If properly designed, constructed and maintained, your septic system can provide long-term, effective treatment of household wastewater. If your septic system isn’t maintained properly, you may need to replace it, causing you to spend money needlessly.
The typical household septic system should be inspected from one to three years depending on the complexity of the system. Every three years for a gravity system, once a year for all others.
