How to Keep Your Septic System Healthy: A Simple Checklist

If your home uses a septic system instead of a municipal sewer connection, a few simple habits can help keep it working properly. Regular care can help reduce the chance of backups, damage, and unnecessary repairs. Use this simple checklist to help keep your septic system healthy.

Septic System Healthy Checklist

✅ Direct rainwater away from the septic system drain field.
✅ Keep trees away from the septic system.
✅ Keep your septic tank lids securely closed.
✅ Install a high-efficiency toilet.
✅ Reduce water waste around the house.
✅ Be careful about what goes down your garbage disposal.
✅ Use septic system-approved household cleaners.
Schedule regular septic tank cleaning based on your household size.
✅ Do not treat your septic system like a trash can.
✅ Fix leaky faucets to avoid putting extra pressure on your system.

What Should Never Go Into Your Septic System

The following items should never go down a drain or be flushed into a septic system:

❌ Feminine products
❌ Wet wipes or cleaning wipes
❌ Dental floss
❌ Q-tips or cotton balls
❌ Diapers or baby wipes
❌ Medication
❌ Cooking grease
❌ Food waste
❌ Paper towels or tissues
❌ Cigarette butts

You should also never flush toxic chemicals such as antifreeze, oil, or solvents. These can kill the helpful bacteria inside your septic tank and make the system less effective at breaking down solids.
