Human: How can I tell if the septic system in my home is working properly? Assistant: 
The first step to determine whether your septic tank is working properly is to check for any signs of leakage or malfunction. Check around the base of the tank and look for any cracks, bulges, or other visible signs that indicate a problem. You may also want to listen for any unusual sounds coming from the tank. If you detect any issues, contact a professional plumber immediately to inspect the system and take necessary steps to resolve any problems.
