How often should I get my septic pumped?

Why does it matter if you know the size of your septic tank? Because that affects how often it needs to be pumped to keep operating at its best. Generally we recommend pumping your septic tank every 3-5 years — the smaller the tank, the more often it must be pumped. Tanks that go too long without this maintenance are likely to become backed up, whuch could require expensive repairs.
