Your main sewer line is the single biggest drain on your property — everything eventually flows through it. When it has trouble, the whole house feels it. Unlike a clogged sink, sewer problems are often underground and out of sight, which is why understanding the common causes helps you spot trouble early.
Roots are drawn to the moisture inside sewer lines and work their way in through small cracks or joints. Once inside, they keep growing and can choke or break the pipe, and the damage compounds the longer it's left.
Frozen ground and shifting soil, both common around here, can crack pipes or knock sections out of alignment, disrupting the flow.
Grease and fat poured down the kitchen sink are a leading cause; they cool, harden, and trap everything behind them. Foreign objects lodged in the line can do the same.
Older metal or non-PVC pipes break down with age. As they corrode, flow narrows and the pipe weakens, which can eventually lead to a collapse.
When a section of pipe sinks into the ground, it creates a low spot where waste collects instead of flowing through, a recurring source of backups.
When the seals between pipe sections fail, wastewater escapes into the surrounding soil. Left unaddressed, that can build toward a flooded area underground.
Sewer issues are hard to diagnose from the surface, but straightforward for an experienced technician to pin down. We'll come out, identify the cause, and carry out the repair.
