Whole-home slow drains occur when wastewater cannot move freely through the septic line or drainfield, causing backups and sluggish flow. Common causes include clogged filters, failing drainfields, solids reaching laterals, root intrusion, pipe blockages, and hydraulic overload from too much water use. This guide teaches homeowners how to identify whether the issue is inside the home or coming from the septic system. The Septic Saver course provides step-by-step strategies for improving flow, preventing overload, restoring bacterial activity, and increasing soil absorption. With proper education and maintenance, most slow-drain septic issues can be prevented. This guide gives homeowners the knowledge they need to protect their property and extend the lifespan of their septic system.
