How often should a septic tank be inspected?

Septic tanks should be inspected regularly to ensure they are functioning properly and to prevent potential failures that can lead to environmental contamination and health hazards. The most widely accepted recommendation is to have a septic tank inspected every 3 to 5 years, depending on the size of the tank, the number of people using it, and the specific conditions of the household.

An inspection frequency of biannually, as the selected answer suggests, is more frequent than standard guidelines typically recommend. While more frequent inspections can certainly help identify and resolve minor issues before they become serious problems, the standard practice generally advises inspections conducted at least every 3 to 5 years for routine maintenance. This ensures the tank's integrity and function without the more excessive schedule that might not be necessary for every household.

Regular maintenance includes not only inspection but also pumping the tank when necessary, which can depend on the volume of waste produced in relation to the tank's size. The goal of these inspections is to prolong the life of the septic system and safeguard public health and the environment.
