Why Pump Septic Tank Every Five Years?

Why Pump Septic Tank Every Five Years?

Published on March 2, 2023

Septic tanks need to be pumped every 3-5 years to remove the accumulated solids and scum that settle at the bottom of the tank. If these materials are not removed regularly, they can reduce the tank’s capacity, clog the discharge pipes, and eventually cause the system to fail. Pumping the tank ensures that it continues to function effectively and prevents more serious and expensive problems from arising in the future, such as a backup into the home, or a failed drain field.

Accumulated solids in a septic tank are the organic and inorganic materials that settle at the bottom of the tank over time. These materials include human waste, toilet paper, fats, oils, grease, and other household waste that are not broken down by the bacteria in the tank. Over time, these solids accumulate and form a layer that can reduce the capacity of the tank, clog discharge pipes, and negatively impact the overall performance of the septic system. Regular septic tank pumping helps to remove these accumulated solids, keeping the system functioning properly.

5 years is the longest a septic tank should ever go without being pumped. However, the frequency of septic tank pumping depends on several factors, including the size of the tank, the number of people living in the home, the volume of waste water produced, and the level of solids accumulation. As a general guideline, it is recommended that septic tanks be pumped every 3 to 5 years to maintain proper functioning. However, it is recommend pumping every 2 to 3 years for households with heavy usage. Regular pumping helps to prevent problems and ensures the long-term health of your septic system.
