Understanding Sewer Line Installation Services

When it comes to sewer line installation services, understanding the different types, materials, and techniques used can help you make informed decisions for your home or business.

Types of Sewer Lines

Sewer lines come in various types based on their function and placement:

  • Residential Sewer Lines: These connect your home’s plumbing system to the municipal sewer system.
  • Commercial Sewer Lines: Larger in scale, these serve businesses and commercial buildings.
  • Storm Sewer Lines: Designed to carry rainwater away from streets and properties to prevent flooding.

Materials Used

Sewer lines can be made from different materials, each with its pros and cons:

  • PVC (Polyvinyl Chloride): Lightweight, easy to install, and resistant to corrosion. It’s commonly used in modern installations.
  • PEX (Cross-linked Polyethylene): Flexible and durable, ideal for tight spaces and areas prone to ground movement.
  • Clay Pipes: Traditional material, durable but heavy and prone to root intrusion.
  • Cast Iron: Strong and long-lasting, often used in older systems but can corrode over time.
  • Concrete: Extremely durable and used for large-scale projects, but can be expensive and difficult to handle.

Installation Techniques

Different techniques are used depending on the project requirements and site conditions:

  • Open Trenching: The most common method where a trench is dug to lay the sewer pipe. While effective, it can be disruptive to the surrounding area.
  • Trenchless Technology: A less invasive method that includes techniques like pipe bursting and slip lining. This method reduces excavation and is faster but can be more expensive initially.

Pipe Bursting

This technique involves breaking the old pipe while simultaneously pulling in a new one. It’s ideal for replacing old, damaged pipes without extensive digging.

Slip Lining

Slip lining involves inserting a smaller diameter pipe into the existing sewer line. This method is used for repairing leaks and restoring the integrity of the sewer line without full replacement.

Case Study: Successful Sewer Line Installation

A recent project in Dallas, TX, involved replacing an old clay sewer line with a new PVC pipe using the trenchless pipe bursting method. The homeowners noticed slow drains and a soggy yard, classic signs of a failing sewer line. Auger Pros Plumbing used state-of-the-art equipment to locate the issue and completed the replacement with minimal disruption to the property.

By understanding the types, materials, and techniques involved in sewer line installation services, you can better appreciate the complexity and importance of this essential service. Next, we’ll dive into how to prepare for sewer line installation, ensuring a smooth and efficient process.

Preparing for Sewer Line Installation

Before any sewer line installation can begin, it’s crucial to prepare properly. This involves three key steps: site assessment, obtaining permits, and implementing safety measures.

Site Assessment

The first step in preparing for sewer line installation is a thorough site assessment. This involves:

  • Identifying Existing Utilities: Before digging, locate any existing utility lines, such as gas, water, and electricity. This helps prevent accidental damage and ensures safety.
  • Soil Analysis: Understanding the soil type is important because it affects excavation and pipe laying. For example, sandy soil requires different handling compared to clay.
  • Slope and Elevation: Proper sewer lines rely on gravity to function. Ensuring the correct slope is critical for effective drainage. Go Pro Plumbing uses advanced tools to measure and plan the slope accurately.


Permits are a legal requirement for sewer line installation. They ensure that the work complies with local building codes and regulations. Here’s what you need to know:

  • Application Process: You may need to submit detailed plans and pay a fee. The process can take a few days to several weeks, depending on your location.
  • Inspections: Once the permit is issued, expect inspections at various stages of the installation. This ensures the work meets all safety and quality standards.
  • Cost: Permit costs can vary, but Go Pro Plumbing can help you understand and manage these expenses effectively.

Safety Measures

Safety is paramount during sewer line installation. Proper precautions protect both the workers and the property. Key safety measures include:

  • Protective Gear: Workers should wear helmets, gloves, and safety glasses to prevent injuries.
  • Excavation Safety: Shoring or trench boxes are used to prevent trench collapses. This is especially important in deep or unstable soil.
  • Traffic Control: If the installation is near a road, proper signage and barriers should be in place to manage traffic and protect workers.
  • Utility Shutoff: Before starting, ensure that any affected utilities are shut off to prevent accidents.

By thoroughly preparing for sewer line installation, you can ensure a smoother and more efficient process. Proper site assessment, obtaining necessary permits, and implementing stringent safety measures are all crucial steps.

Step-by-Step Process of Sewer Line Installation

Let’s walk through the sewer line installation process, breaking it down into simple, easy-to-follow steps: Excavation, Pipe Laying, Connection, and Backfilling.


1. Marking the Area:
The first step is to clearly mark the area where the sewer line will be installed. This helps avoid any confusion and ensures the excavation is done accurately.

2. Digging the Trench:
Using heavy machinery, dig a trench along the marked path. The trench should be deep enough to accommodate the sewer pipe and provide a slight slope for gravity to assist in waste flow.

Tip: The trench should have a minimum slope of 1/4 inch per foot to ensure proper drainage.

3. Shoring and Safety:
If the trench is deep, use shoring to prevent the walls from collapsing. Safety is paramount, so ensure the trench is stable and safe for workers to enter.

Pipe Laying

4. Laying Down the Bedding:
Before placing the pipes, lay down a bedding layer of sand or gravel. This provides a stable base and prevents the pipes from shifting.

5. Installing the Pipes:
Carefully place the sewer pipes into the trench. Ensure that the pipes are aligned correctly and maintain the necessary slope. Use pipe connectors to join sections securely.

6. Sealing the Joints:
Apply sealant or use rubber gaskets at the joints to prevent leaks. Proper sealing is crucial to avoid future issues.


7. Connecting to the Main Sewer Line:
Once the pipes are laid, connect the new sewer line to the main sewer system. This may require cutting into the existing line and using special connectors.

8. Testing the Connection:
After making the connection, test the system for leaks. Fill the pipes with water and check all joints and connections for any signs of leakage.

Fact: According to Go Pro Plumbing, properly testing the connection can save a lot of hassle and prevent costly repairs down the line.


9. Covering the Pipes:
Once the connections are secure and leak-free, start backfilling the trench. Use the excavated soil, ensuring it’s compacted well to prevent future settling.

10. Restoring the Surface:
Finally, restore the surface to its original condition. This may involve replacing grass, paving, or any other surface material that was removed during excavation.

By following these steps, you can ensure a successful sewer line installation that functions efficiently and lasts for years.

Sewer Line Installation Costs and Factors

When it comes to sewer line installation services, several factors can influence the overall cost. Let’s break down the main components: material costs, labor, duration, and unexpected expenses.

Material Costs

The type of material used for the sewer line significantly impacts the cost. Here’s a quick look at common materials and their price ranges:

  • ABS Plastic: $140 to $260 per 50 linear feet

PVC is often the most cost-effective option, while cast iron, though more expensive, offers durability and longevity.


Labor costs can vary based on the complexity of the job and the location. On average, plumbers charge between $45 and $165 per hour. Go Pro Plumbing offers competitive rates and can provide a detailed quote based on your specific project needs.


The time it takes to complete a sewer line installation can range from a couple of days to over a week. Factors influencing the duration include:

  • Length of the sewer line: Longer lines take more time.
  • Depth of excavation: Deeper lines require more labor.

It’s crucial to hire a professional plumber to ensure the connection is done correctly and complies with local codes.

How does a sewer line get clogged?

Sewer lines can get clogged due to various reasons:

  • Tree Roots: Roots can infiltrate sewer lines, causing blockages and even breaking the pipes.
  • Debris and Grease: Items like food scraps, grease, and non-flushable products can accumulate over time, leading to clogs.
  • Pipe Damage: Cracks or breaks in the sewer line can cause debris to catch and build up, resulting in a blockage.
  • Sagging Pipes: Over time, soil conditions can cause pipes to sag, creating a spot where waste accumulates.

Regular maintenance and inspections can help prevent clogs and identify potential issues before they become major problems.

How to flush sewer pipes?

Flushing sewer pipes can help clear minor blockages and maintain the health of your sewer system. Here’s how to do it:

  1. Use Hot Water: Pour hot (not boiling) water down the drain to help dissolve grease and soap scum.
  2. Baking Soda and Vinegar: Pour half a cup of baking soda followed by half a cup of vinegar down the drain. Let it sit for 15 minutes, then flush with hot water.
  3. Enzyme Cleaners: These products contain bacteria that break down organic matter. Follow the instructions on the product label.
  4. Hydro Jetting: For more stubborn clogs, professionals can use hydro jetting, which involves using high-pressure water to clear the pipes.

While these methods can help maintain your sewer lines, they are not substitutes for professional cleaning and inspections.
