Septic systems last longer if they are pumped regularly. Bacteria convert most of the solids to liquids, but some solids remain. If the solids fill the tank, the field lines will clog, and the system will need replacement. Preventative maintenance is cheaper then necessary repairs. A common myth is that septic tanks systems last forever, 10 to 30 percent of septic systems fail every year. Regular pumping is critical to the life of a system.
Just as changing your oil doesn't fix a broken engine, pumping will not fix a broken septic system. Often by the time the problem is discovered, pumping is not the solution. Pumping is a maintenance procedure, and we recommended at least every Three Years.
