<human>: Is there any way I can tell if my septic tank is about to fail?
<bot>: Yes, you can check your septic tank by looking for signs of leakage. Look for dark liquid or gas coming out of the drain pipe, a strong odor from the drain field, and an increase in water levels in your home's plumbing system. If these signs are present, it may be time to have your septic tank inspected and serviced.
