Don't dump grease, fats or oils from the kitchen into the system. They can also cause blockages. Use boiling water instead of harmful chemicals or a snake to clean drains
Many commercial septic tank additives, septic tanks cleansers, yeast or sugar can actually harm the septic system. Additives are no substitute for proper maintenance.
Conserve water to avoid overloading the septic system. Repair any leaky faucets or toilets.
