Whether facing collapsed cast-iron piping, severe tree root blockages, or outdated clay lines, Pace Plumbing brings over 20 years of local experience to every excavation project.
When is a full sewer line replacement required for your property?
A full sewer line replacement is required when underground pipe deterioration, recurrent root intrusion, or major structural collapses prevent wastewater from draining to the municipal main or septic network. Pace Plumbing evaluates main drain conditions with advanced video diagnostic equipment to determine whether localized repairs or a full line replacement is needed.
Older homes in Spokane County frequently feature clay or cast-iron drain lines that weaken over decades of seasonal ground shifting. When lines experience repeated blockages, sagging sections, or persistent root intrusion, installing a new sewer system prevents chronic plumbing emergencies and structural foundation damage.
Signs of Underground Sewer Pipe Damage
Property owners should monitor drain systems for specific warning signs that indicate main line failure:
Persistent drain backups affecting multiple plumbing fixtures at the same time.
Unexplained indentations or unusually lush, soggy patches across the lawn.
Sewer gas odors emanating from indoor floor drains or outdoor yards.
Gurgling sounds originating from toilets when secondary drains discharge water.
Structural foundation cracks or sinkhole formation along the sewer line path.

What are frequently asked questions about sewer pipe replacement?
Property owners often ask about project timelines, root intrusion damage, and available service discounts before starting an excavation. Pace Plumbing provides direct, transparent answers so you know exactly what to expect from your underground plumbing upgrades.
How long does a standard sewer line replacement take?
Most residential sewer line installations require two to five days to complete, depending on the trench depth and Spokane County inspection schedules. Our licensed plumbers work diligently to secure the required permits, perform the excavation, and lay the new PVC piping with minimal disruption to your property.
Can tree roots destroy underground plumbing lines?
Yes, aggressive tree roots naturally seek out the moisture inside older clay and cast-iron sewer pipes, eventually penetrating the joints and fracturing the structural walls. Once roots severely compromise the pipeline, installing a continuous, durable PVC system is the only permanent solution to stop recurrent wastewater backups.
