Sewer line repairs and replacement in Spokane keep your plumbing system working, prevent backups, and protect your property from costly damage. Sewer lines can fail due to age, tree roots, clogs, or shifting soil. Knowing the signs, repair methods, and replacement options help homeowners and business owners make smart decisions and avoid emergencies.
Signs You Need Sewer Line Repairs or Replacement
Recognizing early warning signs can save you from expensive repairs. Common signs include:
- Slow drains in sinks, tubs, or toilets
- Gurgling sounds from pipes
- Foul odors near drains or outside
- Multiple fixtures clogging at once
- Water backing up in showers or toilets
- Soggy spots or sinkholes in the yard
If you notice these issues, it may be time for a plumbing video camera inspection to pinpoint the problem.
What Causes Sewer Line Problems?
Sewer lines can fail for several reasons:
- Tree root intrusion: Roots seek out moisture and can break or block pipes.
- Pipe corrosion: Older pipes made of cast iron, clay, or Orangeburg deteriorate over time.
- Clogs: Grease, wipes, and debris can block pipes and cause backups.
- Ground shifting: Soil movement or settling can crack or misalign pipes.
- Aging infrastructure: Most sewer lines last 40–60 years before needing replacement.
Drain cleaning and regular maintenance can help prevent many of these problems.
Sewer Line Repair Methods
There are several methods for repairing a damaged sewer line in Spokane. The right sewer and drain repair service depends on the extent and location of the damage.
Cured-in-Place Pipe (CIPP) Lining
CIPP lining is a trenchless repair that inserts a resin-soaked liner into the damaged pipe. The liner hardens and creates a new pipe inside the old one. This method is less invasive and can extend the life of your sewer line by decades.
Pull-In-Place Lining
This method uses a pre-shaped liner pulled through the pipe and cured with hot steam. It is effective for large cracks or gaps and requires access at both pipe ends.
Pipe Bursting
Pipe bursting replaces old pipes by breaking them apart while pulling in a new pipe. This trenchless method is ideal for severely damaged or collapsed lines and can install pipes that last up to 100 years.
Sliplining
Sliplining involves inserting a smaller pipe into the old one and sealing the ends. It is quick and effective but reduces the pipe’s diameter.
Internal Pipe Coating
A thick epoxy coating is sprayed inside the pipe to seal leaks and prevent future damage. This is best for small leaks or as a preventive measure.
Traditional Excavation
Traditional repair involves digging up the old pipe and replacing it with a new one. This method is used when trenchless options are not possible or when pipes are severely damaged.
Comparison of Sewer Line Repair Methods in Spokane
| Method | Invasiveness | Lifespan | Best For |
| CIPP Lining | Low | 50+ years | Cracks, leaks, small breaks |
| Pipe Bursting | Low | 50–100 years | Collapsed or old pipes |
| Sliplining | Low | 30–50 years | Long, straight sections |
| Internal Coating | Low | 10–20 years | Small leaks, prevention |
| Excavation | High | 50+ years | Severe damage, no access |
How to Choose the Right Repair or Replacement Method in Spokane
Choosing the best method depends on the following:
- The extent of the damage: Minor cracks may only need lining; major breaks may require bursting or excavation.
- Pipe material and age: Older materials, such as clay or Orangeburg, often require full replacement.
- Location: Pipes under driveways or landscaping benefit from trenchless repairs.
- Budget: Trenchless repairs often cost less overall due to the minimal property damage they cause.
A sewer system backup can signal the need for urgent repair or replacement.
The Advantage of Trenchless Sewer Line Repair
Trenchless sewer line repair is popular because it:
- Minimizes yard and property damage
- Is faster, often finished in a day
- Reduces labor and restoration costs
- Installs durable, corrosion-resistant pipes
Trenchless sewer line repair is ideal for most modern homes and businesses.
When Is Sewer Line Replacement in Spokane Necessary?
Replacement is needed when:
- Pipes are collapsed or severely corroded
- Multiple repairs have failed
- The line is made of outdated materials
- Major root intrusion or misalignment occurs
Replacement methods include pipe bursting, slip lining, and traditional excavation. The cost depends on the pipe length, depth, and access requirements.
