Why do I need my septic tank pumped? and How often do I need to pump my tank?
There are solids that collect in the bottom of your septic tank. These solids are not meant to pass into your absorption field. If these solids get into the absorption field, they can plug it and cause irrepairable damage. It is important to have your tank pumped and cleaned on a regular basis to prevent the buildup of these solids and to increase the longevity of your septic system. Depending upon usage and the size of your tank, it is recommended that your tank be pumped and cleaned every 2-4 years. The use of food disposals, powder laundry detergents, excess amounts of cleaning agents and heavy use of medications (like chemotherapy) may lead to the need for more frequent cleanings.
