Septic tank owners should have their tanks pumped approximately every three to five years to avoid clogs and other issues, recommends the Massachusetts Department of Energy and Environmental Affairs. Septic tanks are also pumped to fix certain problems, including clogs and blockages.
Septic systems that are heavily used or those that service large households might need to be pumped on a more frequent basis.
Homeowners need to carefully choose septic tank pumping services that are properly licensed and insured. After the service is performed, the company must provide a detailed receipt that lists the date, total cost and how many gallons were pumped.
