At Drainbo, we understand that septic system cleaning isn’t generally something you think about on a regular basis. That’s why we have created a guide of how often to clean your septic tank to make sure it’s operating at peak efficiency: 

If you have a septic system that is less than three years old, you typically only have to treat it twice per year. 
For septic systems that are five years old, it is recommended to treat them with our all natural septic treatment every 3-4 months. 
Septic tanks that are older than five years should be treated every 3 months or 4 times per year.
