How often should my septictank be serviced?
Local health departments recommend that the accumulated solids in the bottom of the septic tank be pumped out every three to five years. The more people using a system, the more quickly the solids accumulate, and the more often the tank will need to be pumped. Also, using a garbage disposal increases the solids in a septic tank. Pumping out the tank on a regular basis will help prevent solids from entering the drainfield and causing blockages in the drainfield.
