How often should septic tank systems be pumped according to the Massachusetts Plumbing Code?

Septic tank systems should be pumped out every 2 to 3 years, depending on usage, as per the Massachusetts Plumbing Code. This timeframe is recommended to ensure the long-term functionality and efficiency of the septic system. Regular pumping helps to remove accumulated solids that can lead to clogs and system failure if left untreated. The frequency may vary based on the size of the tank, the number of people in the household, and the amount of wastewater generated. By adhering to this guideline, homeowners can prevent potential issues that may arise from neglecting their septic system, ensuring proper sewage treatment and protecting the environment.
