How often should a septic system be cleaned?
It depends. A tank should be pumped and inspected every 2 years, but frequency of cleaning depends on the size of the tank and the use it is given. If the solids settle to the bottom of the tank and are not pumped out at proper intervals, they can be carried out into the leaching system and may clog the leaching pipes. This could cause system failure. A failure could require replacing the system at a cost of thousands of dollars.
