Septic Tank Pumping
The number one reason for premature septic problems is due to the lack of pumping. Most people believe tanks don't need to be pumped. This is simply wrong. The sludge is slowly flowing out of the tank, clogging the absorption lines. This causes lateral lines to fail, costing you thousands to repair.
The trash tank on most aerobic units are 400 to 500 gallons. Most aerobics will need to be pumped every 2-3 years. However, if there is a higher number of occupants (heavy usage) in the household some aerobics will need to be pumped every 1-2 years.
The same is true for aerobic treatment units...
The tanks should be pumped out before the sludge builds up. Too much sludge causes backups and premature component failure. Leaving the homeowner with costly repairs sooner than normal.
