What causes septic line clogs
Septic lines can become clogged for several reasons. The most common cause is accumulation of solids that shouldn't be in the system—flushable wipes, feminine products, paper towels, and other non-biodegradable items can build up and create blockages. Grease and fat poured down drains can solidify in the pipes and create stubborn clogs.
Tree root intrusion is another major cause of clogs, especially in older homes. Roots can crack or penetrate pipes in search of water, eventually creating a blockage. Physical damage from settling soil, construction, or freezing temperatures can also cause pipes to collapse or become misaligned, creating flow restrictions.
