To prevent sewer line clogs, avoid flushing non-biodegradable items like wipes, feminine hygiene products, and paper towels down the toilet. Dispose of grease and food scraps properly, as they can solidify and block the line. Regularly clean your drains and use a strainer to catch debris. Consider scheduling annual sewer line inspections to catch potential issues early. If you have trees near your sewer line, monitor for root intrusion, which can cause significant blockages over time.
