To prevent toilet clogs, avoid flushing non-flushable items like wet wipes, paper towels, and feminine hygiene products. Use toilet paper sparingly and consider using thinner, septic-safe toilet paper. Regular maintenance, such as cleaning jets and flushing lines with hot water, can also help prevent clogs. If you experience persistent clogs, it may be a sign of an underlying issue, and it's best to consult a professional for diagnosis and repair.
