Sewer Line Inspection & Repair

The main sewer line is the part of a home's plumbing most people never think about until it fails, and when it does, it affects every drain in the house at once. Pasco Plumbing inspects and repairs sewer lines throughout Washington using camera equipment to see exactly what's happening underground, rather than digging based on guesswork.

Sewer line problems range from a partial blockage that can be cleared, to a cracked or root-infiltrated section that needs to be repaired or replaced. We diagnose first, explain what the camera shows in plain terms, and then walk you through repair options — including trenchless methods that can avoid tearing up an entire yard or driveway when the situation allows for it.

Signs You Need Sewer Line Inspection & Repair

• Multiple drains throughout the house backing up at the same time
• Gurgling from toilets or drains when other fixtures are used
• Sewage odor in the yard, basement, or near a cleanout
• Unusually lush, green patches of grass over the sewer line path
• Slow drainage throughout the house that isn't fixed by clearing individual fixtures
• Sinkholes or soft, sunken areas in the yard along the sewer line's path
• Sewage backing up into the lowest drain in the house, often a basement floor drain
• A home with mature trees near the sewer line and a history of clogs

Camera Inspection: Seeing The Problem Instead Of Guessing

A sewer camera is a waterproof, flexible camera fed directly into the line, giving us a real-time view of the pipe's interior condition — root intrusion, cracks, bellies (sagging sections where waste collects instead of flowing through), offset joints, or a collapsed section. This matters because sewer line problems can look identical from the symptoms alone but require very different repairs.

We record the inspection and can show you directly what's happening in your line, at what distance from the cleanout, so the recommendation we make isn't just our word for it — you can see the same thing we're seeing. This also lets us target repairs precisely rather than excavating an entire line when only one section actually needs work.

Repair Options: Traditional Vs. Trenchless

Traditional sewer repair involves excavating the ground above the damaged section to access and replace the pipe directly. It's sometimes the right and most economical choice, particularly for a short, accessible section of damaged pipe. For longer runs or sewer lines under driveways, mature landscaping, or other structures, trenchless methods — such as pipe lining or pipe bursting — can repair or replace the line with far less surface disruption.

Not every property or every type of damage is a fit for trenchless repair; a badly collapsed section, for instance, may still require excavation. We evaluate what the camera shows and recommend the method that actually fits your situation, explaining the trade-offs between cost, disruption, and long-term durability for each option.

Root Intrusion: A Common Culprit In Washington Yards

Tree roots are drawn to the moisture and nutrients inside a sewer line and will exploit even small cracks or loose joints, gradually filling the pipe and restricting flow until a full blockage develops. This is especially common in older neighborhoods with mature trees close to the sewer line's path. Clearing roots addresses the immediate blockage, but if the underlying crack or joint isn't repaired, roots typically return. We'll tell you honestly whether a cleaning alone is enough or whether the entry point needs to be repaired to solve the problem long-term.
