If you ask a septic professional how often you should pump your tank, you will get either a short or long answer. The short answer is “it depends” while the longer one will most likely include a long list of variables. Here are some factors that will affect how often you need septic tank pumping:
Tank size. Your septic tank was designed for the size of your home, usually based on the number of bedrooms in the house. The bigger the tank, the less often it will need to be pumped.
Household members. The tank size versus the number of people in your household will influence how often you need to have a pumping service. A big house with only 2-3 people may be able to go three years or more without pumping. A 2-bedroom home with four adults living in it may need septic tank pumping every year.
Special events. Big parties or guests through the holidays can impact how often you need your tank emptied.
Age of the system. An older septic system may not be as efficient, requiring more frequent septic tank pumping.
Garbage disposal. If you use a garbage disposal in your home, it can increase the solid waste in your tank. Consider composting or other options if you want to reduce solid waste.
Vacations and other homes. If you take frequent trips or vacations, you may not need to have your tank pumped as often.
There is not a simple answer to how often you will need your septic tank pumped; it can change as your life changes. The best way to stay on top of your pumping schedule is to have your tank and system inspected by a septic professional annually.
