Common mistakes when installing sewer line and how to Prevent them

Sewer line installation is a high-stakes situation. In order to keep any property, whether residential or commercial, hygienic and functional, a properly installed sewer line is essential. Sewer line installation errors can, regrettably, result in expensive repairs, environmental risks, and major annoyances. Learn about common installation errors for underground sewer pipes and get tips on how to prevent them by reading on.

Incorrect Slope and Alignment

The installation of a sewer line involves fundamental aspects such as proper slope and alignment, which are crucial for ensuring proper flow and preventing sewage backups. Hiring experienced professionals, using laser or GPS technology, and regularly inspecting and maintaining the sewer line are essential to avoid costly repairs.

Inadequate Pipe Material

The choice of the right sewer line pipe material, such as HDPE or PVC, is crucial for its longevity and resistance to corrosion. Regular inspection and consulting with experts can help prevent leaks and reduce the lifespan of the sewer line.

Insufficient Ventilation

The sewer system requires adequate ventilation to function effectively. Proper installation of pipes, adherence to building codes, strategic placement, and frequent inspections are crucial to prevent clogs and ensure smooth flow.

Neglecting Permits and Regulations

The entire installation of a sewer line requires compliance with local regulations and permits, as ignoring these can lead to legal issues and the need for a redo.

Improper Installation Depth

The installation of a sewer line is crucial to avoid potential damage from surface activity and challenges in accessing for repairs. It’s essential to find the right depth, avoid encountering underground obstacles, and assess the sewer line’s condition regularly.

Prevention these mistakes

For the property to remain hygienic and functional, a sewer line installation must be completed successfully. When it comes to future sewer line repairs, avoiding common installation errors can save time, money, and headaches. Seek advice from professionals who are knowledgeable about the complexities of the procedure and how crucial it is to stay clear of these pitfalls in order to guarantee a precise and seamless sewer line.

Parts of a Sewer Pipe

Most sewer pipes are composed of four major components: the barrel, bell, spigot, and gasket.

Barrel

The barrel is part of the pipe’s body, which also includes its outer and inner walls.

Bell and spigot

When two sewer pipes are connected, they typically use a bell and spigot joint, where the bell end flares to a slightly wider diameter to fit neatly together and the spigot end of one pipe has the same diameter as the pipe’s length.

Gasket

A gasket is a ring that fits around the inside of the bell and aids in sealing the joint between two pipes. It is frequently made of rubber. Although some pipe and gasket types need to be attached on-site, these gaskets are frequently attached by the factory prior to installation. This frequently depends on the manufacturing material.

Materials of Sewer Pipes

Pipes can be constructed from a variety of materials. Although many older pipes are still in use and need routine maintenance, standards have evolved over the years. Teams involved in rehabilitation, cleaning, and inspection must be knowledgeable about a range of pipe materials in order to correctly identify flaws, vulnerabilities, and possible fixes.

Concrete

Concrete pipes, a common practice among contractors, can be polymer-coated, prestressed, reinforced, or lined with clay. Concrete pipes are frequently constructed from unprocessed, natural materials and are thought to be environmentally friendly. Although they need to be installed carefully and maintained frequently, they are resistant to corrosion and environmental damage in many ways.

Plastic

Plastics such as acrylonitrile butadiene styrene (ABS), high-density polyethylene (HDPE), and polyvinyl chloride (PVC) are lightweight options for wastewater infrastructure. They’re not only flexible and simple to install, but they also resist corrosion, come in longer pipe sections than most other materials, and are generally less expensive. One of the drawbacks of plastic pipes, according to the EPA, is that sunlight can occasionally weaken them, which makes it more crucial to store them properly than other materials. They can also be attacked chemically, particularly by solvents.

Clay

Many residential sewer systems still use clay pipes, though they are not as prevalent as they formerly were. Despite their potential for brittleness and cracking, vitrified clay pipes are now highly resistant to the majority of corrosion thanks to advancements in manufacturing techniques. Their application is restricted to gravity sewers.

Metal

Pitch fiber, also referred to as Orangeburg pipe, gained more attention during World War II due to a shortage of steel, even though cast iron was still utilized in many underground systems in the early 1900s. Later, ductile iron pipes took the place of cast iron and were chosen for applications where the most important requirements are pipe strength and durability. Cast iron is much less common now than it was in the past, though, because it is heavy, costly, and prone to rust.

How to install Sewer Line

Determine the Pipe’s Depth

The first step is always to determine each pipe’s elevation. Most residential installations begin with the main drain, which is typically located on the foundation of the house. At a point known as a tap, the line continues on to connect with the city’s main branch. The elevations can be found using a laser level or a GPS.

Compute the Slope

The basis for calculating slope is provided by the depth and pipe length results.

Ending Elevation minus Starting Elevation is the total elevation drop.

To calculate the slope, divide the total drop by the pipe’s length or run.

For the majority of laterals, the standard minimum slope is typically 2%, or two feet for every 100 feet of run. The variation should fall within the bounds of the local code, even if the actual slope is steeper than the target. Furthermore, a steep slope will encourage liquids to flow more readily than solids, which can result in clogs. A shallow slope will therefore not produce enough velocity for effective drainage.

Dig the trench and Lay the Bleeding

To reduce the amount of soil disturbance, dig the trench carefully. Compaction can reduce soil disturbance. This can only be accomplished by excavating a narrow trench and having adequate knowledge of the pipe’s termination point. Additionally, make sure the canal is compacted, smooth, and slopes according to the intended path. Before installing the pipes, fine-tune the area and slope the soil with sand.

Install the Pipe

Install each pipe beginning at the line’s lower end and working your way up to the higher elevation. To minimize leaks, each pipe section’s bell end should be positioned facing uphill. For easier access to the pipe during scoping or sewer auger cleaning, the house ends should have at least two cleanouts.

Back Fill the Trench

Backfill the trench after the installation is finished and all inspection requirements have been met. To fill in any gaps and shield the pipe, start with a layer of sand. To avoid future settling, finish by adding more soil layers and compacting each one.

Conclusion

The success of installing sewer line hinges on careful planning, the right materials, and adherence to regulations. By understanding the common mistakes and following best practices, property owners can ensure a reliable sewer system that minimizes future issues. Regular inspections and professional guidance are essential to maintaining the integrity of the installation, ultimately protecting both the property and the environment from potential hazards and costly repairs.
