How often
Angi suggests every three to five years for most homes, more often for larger households.1 On an aerobic system, your maintenance provider checks sludge levels and will tell you when pumping is needed. In Bexar County, standard (non-aerobic) system permits are renewed every 5 years by pumping the tank and submitting a pump receipt.2
Tips
- Only flush toilet paper and human waste3
- Do not drive or park on the tank or drain field1
- Keep your pump receipts; you may need them for permits or a home sale
