How Often To Clean Septic Tank Filter. Cleaning your septic tank regularly will help to avoid excess scum and sludge accumulation to free up space for decantation. The department of health (dep) recommends replacing or cleaning the filter annually.
Still, overly frequent clogging is not the norm for the septic tank filter. What is the difference between a septic tank and a cesspool? At a minimum, your septic tank filter should be cleaned whenever the tank is pumped, or at least every 3 to 5 years.
However, if you have an older system, the alert may come from inside the tank.
As the solid materials accumulate over time, they progressively clog more and more of the filter, requiring maintenance. If this is the case, the sound coming from the monitor will be loud enough for you to hear when walking by the tank. The exact number of years will depend on your region or province. If your septic tank filter clogs frequently, that could be due to excessive water usage or improper waste management.
