How Our Plumbers Install a Sewer Line
Professional sewer installation requires careful planning, technical skill, and attention to detail. We follow a proven process on every job to ensure the work is completed efficiently, safely, and to the highest standard.
- Initial Assessment and Planning: We begin with a thorough site evaluation, often using highdefinition video inspection to understand the existing layout and connections. This allows us to plan the most efficient and least disruptive route for the new sewer line.
- Permitting and Utilities Check: Before any ground is broken, we handle all necessary permitting with the City of Spokane. We also contact 811 to ensure all underground utilities are clearly marked, keeping your property and our crew safe throughout the project.
- Site Preparation and Excavation: Our team carefully prepares the site. Depending on whether a traditional or trenchless method is chosen, we precisely excavate the area needed to access existing connections and lay the new piping.
- New Pipe Installation: The new sewer pipes are installed with the correct slope, which is critical for gravity to effectively carry waste away from your home and prevent future clogs. All work strictly adheres to local building codes.
- Connection and Testing: Once the new pipes are in place, we securely connect them to your home’s plumbing and the municipal sewer line. We then perform hydrostatic testing to verify that all connections are watertight and the system is functioning correctly before filling the trenches.
- Site Restoration: Our commitment does not end when the pipes are buried. We restore the work area as closely as possible to its original condition, cleaning up debris and preparing the site for the next phase of landscaping or construction.
Sewer Installation Methods We Use
Traditional Trenching
Traditional trenching involves excavating along the full length of the sewer line. While more disruptive to landscaping, it is often the right choice for certain depth requirements, severe pipe damage, or specific material needs. We use modern excavation equipment to make this process as fast and clean as possible.
Trenchless Methods
Where conditions allow, trenchless sewer repair and installation offers a minimally invasive alternative that can replace your line with only two small access points, preserving your yard, driveway, and landscaping. Options like pipe bursting and pipe lining are available for many Spokane Valley homes and businesses. We use camera inspection technology during the planning phase to determine whether trenchless is appropriate for your property.
Signs It May Be Time for a Full Sewer System Replacement
A full sewer line replacement is usually necessary when the current system has reached the end of its useful life or sustained significant damage. Knowing the warning signs can help you act quickly and prevent serious property damage.
- Frequent and severe backups throughout multiple drains in your home
- Persistent sewage odors inside or outside your home, especially near fixtures or in the yard
- Unusually lush or soggy patches in your yard above the sewer line
- Foundation cracks or settling caused by a leaking pipe washing away supporting soil
- An aging system with clay or cast iron pipes that have deteriorated over time
If you are experiencing any of these issues, contact us for a professional assessment. We offer detailed sewer line inspections to accurately diagnose the problem and determine whether repair or full replacement is the most cost-effective long-term solution for your home.
Handling Spokane Valley Permits and Local Code
Sewer problems often come to light during real estate transactions or when the City of Spokane identifies code violations. When that happens, fast and correct action is essential. Because our team knows the local permitting process, city regulations, and common site conditions throughout Spokane Valley, we help you avoid unnecessary delays and repeated work.
Whether your property is in an established neighborhood with older infrastructure or a newer development, we tailor our installation approach to address local variables like soil composition, slope, tight property boundaries, and seasonal ground conditions. You will never have to worry about navigating the regulatory side on your own.

Frequently Asked Questions
When does a sewer line need replacing rather than repairing?
When the line has collapsed, when roots have invaded along its length rather than at one joint, when the pipe material has reached the end of its life, or when you are repairing the same line repeatedly. A camera inspection answers it.
How long does a sewer installation take?
Most residential replacements take two to four days depending on length, depth and access. Permitting and inspection add to the calendar, and we build that into the schedule we give you.
Will my yard be torn up?
Not necessarily. Where conditions allow we use trenchless methods, which need access pits rather than an open trench. Where we do have to dig, we show you the route first.
Do you handle permits and inspections?
Yes. Sewer work is permitted and inspected, and we manage the paperwork and the coordination so it is signed off properly.
Can I use the plumbing during the work?
There will be periods where you cannot. We tell you in advance which days and roughly how long, so you can plan rather than be caught out.
What pipe do you install?
Modern materials sized for your property, chosen for the conditions on site. We explain what is going in and why before we start.
Does Spokane Valley's ground cause problems?
Our freeze and thaw cycles move soil, which is hard on older lines and is why bedding and depth matter on a new one. Installing to handle that is the difference between a line that lasts decades and one that settles.
What does a sewer installation cost?
It depends on length, depth, access and method. Estimates are free and in person, you get the full number in writing before we begin, and we offer financing.
