The city provides the sewer line mains to your location, but you are responsible for the sewer line that runs between city lines and your home, and when there’s a problem, it can be smelly and back up your drains.
Most of the time, you won’t notice a sudden problem; it starts small with things like drains that empty slowly, clogs that keep coming back, and that awful sewer gas smell seeping into your home. Homeowners often just assume it’s a minor drain problem, but damage somewhere in the sewer branch line that’s inside your walls or under your floors, or the sewer line that connects to the city under your property, might be quite serious.
How A Home Sewer System Works
Wastewater from every sink, toilet, shower, and appliance in the home travels through a network of pipes that eventually connects to the main sewer line leaving the house. Along the way, individual plumbing fixtures connect to the system through smaller pipes known as a sewer branch line. Each branch line carries wastewater from a specific fixture or group of fixtures before joining the main line.
Because multiple branch lines feed into the main pipe, a problem in one section of the system can affect several fixtures at once. So, step one in figuring out whether you can fix problems in your sewer system is to diagnose the problem.
Common Causes of Sewer Line Damage
Sewer branch lines can leak, crack, or fall victim to mineral buildup. Due to the hard water in the Chandler area, this buildup can clog pipes over time. Drain cleaners might clear clogs from grease or hair, but they won’t take care of mineral buildup.
Main sewer lines are buried underground, starting with beneath your slab, which means they are exposed to soil movement and moisture. Soil expansion, irrigation patterns, and temperature changes place stress on sewer lines and can cause them to shift or crack. Monsoon season doesn’t help, with heavy rain that saturates the soil.
And then there’s tree roots, one of the more common problems. Roots seek out moisture, and they love the nutrient-rich materials in wastewater. So, if there’s a tiny crack or loose joint, they can invite themselves in. As roots grow, they can block pipes and cause them to burst.
When Sewer Line Repair Is Usually Enough
You don’t always need a full replacement. If a plumber can identify a specific section of pipe, they can remove the problem and replace it. For example, getting rid of the section where the root entered the pipe. That can be done without having to do major excavation.
In some cases, a plumber can use a video camera inside the pipes to find the problem and clean out the roots without digging. In other cases, you may need to dig into the soil to repair the damage.
When Full Sewer Line Replacement Is Necessary
In some situations, repairing a single section of pipe will not solve the underlying problem.
A lot of homes in Chandler were built in the 1980s and 1990s. Since a sewer line can last 50-75 years, there’s often plenty of life left. Yet, older plumbing systems may experience corrosion or weak spots in multiple sections of pipes. So, a spot fix may not solve the problem.
For example, when roots have burst into large portions of the sewer line, they may weaken the pipe walls and create repeated failures even after cleaning.
Another situation where replacement may be necessary involves improper installation. Homeowners researching how to run a sewer line will learn the importance of proper pipe slope and alignment, critical for wastewater flow. If the pipe was installed with an incorrect slope or layout, wastewater may repeatedly collect in low areas, leading to frequent blockages. Even if installed properly, soil conditions can change. The sand, silt, and clay in AZ soil shifts over time, especially during heavy rain, which can degrade your plumbing system underground.
In these cases, replacing the line and installing it correctly may provide the only reliable long-term solution.

Sewer Repair and Replacement Costs
You’re probably wondering by now, “How much is this going to cost me?” The short answer is, it depends. Here are some of the factors that influence cost for sewer repair or replacement:
- Location of the damage: If the pipe is near the surface, repairs are simpler. Costs increase significantly if the pipes are deep underground or located beneath a slab, driveway, patio, or landscaping, requiring heavy excavation.
- Length of the pipe: Replacing a short, localized section of pipe is much more budget-friendly than a full-line installation.
- System complexity: Homes with a complex network of sewer branch lines require more labor and precision to ensure all fixtures are correctly reconnected during the process, so costs can vary based on the technical difficult of runninga sewer line.
- Accessibility: The ease with which a plumber can reach the affected area dictates the amount of additional excavation work (and cost) required.
- Professional inspection: Tools like sewer cameras are necessary to determine the structural integrity of the surrounding pipes, which dictates whether a spot fix is even possible or if a more expensive replacement is the only viable long-term solution.
Because every property has a unique plumbing layout, accurate cost estimates usually require a professional inspection of the sewer system.
