RECENT POSTS

Plumbing issues are something every property owner dreads, especially when it comes to sewer line repairs. Traditional methods of repairing or replacing sewer lines are intrusive, expensive, and time-consuming. However, with the advancement in plumbing technology, trenchless sewer line repair has emerged as an effective and convenient option for residential and commercial property owners. Trenchless sewer line repair or replacement eliminates the need for extensive digging while retaining the structural integrity of your pipelines and ensuring a long-lasting, efficient plumbing system.

There are two primary techniques used for trenchless sewer line repair – pipe lining and pipe bursting. Both methods emphasize minimal excavation, keeping your property’s landscape intact. Pipe lining involves inserting a flexible, resin-coated tube into the damaged pipe, which is then inflated to adhere to the interior walls of the existing pipe, forming a seamless new pipe within the old one. On the other hand, pipe bursting involves pulling a new pipe through the old one while simultaneously breaking it apart and replacing the damaged line with a durable, high-density polyethylene (HDPE) pipe.

At New Pro Plumbing, we strive to educate our clients about this innovative approach, equipping you with the knowledge to make informed decisions for your plumbing needs. In this blog post, we will delve deep into the world of trenchless sewer line repair, discussing its benefits and the process involved. This comprehensive guide will help you understand why trenchless sewer line repair has become the preferred choice for many property owners in Los Angeles and the surrounding areas.

Pipe Lining: A No-Dig Solution for Damaged Pipes

Pipelining, also known as cured-in-place pipe (CIPP) lining, is a trenchless sewer line repair method that effectively restores the functionality of damaged pipes without the need for excavation. The process involves the following steps:

1. Inspection: Before proceeding with pipe lining, a thorough inspection of the existing sewer line is conducted using a high-resolution video camera. This process helps identify the extent of damage and any obstructions within the pipeline.

2. Cleaning: Once the problem area is identified, the damaged pipe is cleaned and cleared of any debris or blockages using techniques like hydro-jetting.

3. Preparation: A flexible, resin-coated tube is prepared and customized to fit the exact dimensions and length of the damaged pipe.

4. Installation: The prepared tube is inserted into the damaged pipe and inflated using air or water pressure, adhering to the interior walls of the existing pipe.

5. Curing: The resin hardens, creating a seamless, corrosion-resistant new pipe within the old one. The curing process usually takes around 2 to 4 hours, depending on the size of the pipe and the type of resin used.

6. Final Inspection: Once the new pipe has cured, a final camera inspection is performed to ensure the integrity and proper functioning of the pipe lining.

Pipe Bursting: Replacing Old Pipes with Durable HDPE Pipes

Another trenchless sewer line repair technique, pipe bursting, is more suitable for severely damaged or collapsed pipes that cannot be fixed using pipelining. It involves the following steps:

1. Inspection: Similar to pipelining, the existing sewer line is inspected using a high-resolution video camera to assess the extent of the damage and determine whether pipe bursting is an appropriate solution.

2. Preparing the Entry and Exit Points: Two small pits are dug at the beginning and end of the damaged pipe section, serving as entry and exit points for the pipe bursting process.

3. Pipe Bursting Process: A hydraulic bursting head is inserted into the damaged pipe through the entry pit. The head, which is larger in diameter than the current pipe, is pulled through the old pipe, breaking it apart and simultaneously pulling a new, seamless HDPE pipe in its place.

4. Connection: The new HDPE pipe is connected to the existing sewer line system at the entry and exit points.

5. Final Inspection: A camera inspection is conducted to ensure the proper installation and functioning of the new pipe.

Choosing Between Pipe Lining and Pipe Bursting: Factors to Consider

Both pipe lining and pipe bursting have their advantages and limitations. To determine the most suitable trenchless repair method for your property, consider the following factors:

1. Extent of Damage: Pipelining is ideal for fixing minor to moderate damages, such as cracks or leaks, whereas pipe bursting is more suitable for severely damaged or collapsed pipes that cannot be repaired using pipelining.

2. Pipe Material: Pipelining works for various pipe materials, such as cast iron, PVC, and clay. On the other hand, pipe bursting is better suited for brittle pipe materials or plastic pipes that are prone to fracture.

3. Cost: Generally, pipe lining is less expensive than pipe bursting, as it requires fewer resources and equipment. However, the cost may vary based on factors like the length of the pipe, the location of the damage, and the accessibility of the pipeline.

4. Longevity: Both techniques result in long-lasting solutions, with pipe linings having a lifespan of up to 50 years and HDPE pipes used in pipe bursting being durable for more than 100 years.

The Importance of Professional Guidance and Expertise

While trenchless sewer line repair techniques offer numerous benefits, it is crucial to seek professional guidance and expertise for a successful outcome.

We had a sink stop up that, despite our best efforts, couldn't be solved alone. So...I found Miguel via yelp and relied on the other great reviews on here. He, unlike everyone else we called, came out with no upfront service charge, on a Saturday evening and fixed our clogged pipes for a very reasonable cost. We are keeping his contact info on file and definitely plan to make him our go-to guy. Highly recommend
