What is a Sewer Replacement?

A properly functioning sewer system is essential for the health and safety of your home or business. When sewer lines become damaged or deteriorated, it can lead to serious problems that require professional attention. Our Seattle plumbing company offers expert sewer replacement and sewer repair services to address all your sewer system needs and ensure your plumbing operates smoothly.

Sewer replacement involves removing old, damaged, or deteriorated sewer pipes and installing new ones. This process is necessary when pipes are beyond repair due to extensive damage, corrosion, or root intrusion. Sewer replacement can be performed using traditional excavation methods or modern trenchless technology, which minimizes disruption to your property.

What is Sewer Repair?

Sewer repair addresses specific issues within your sewer lines without the need for complete replacement. Common repairs include fixing leaks, cracks, blockages, or partial collapses. Depending on the severity and location of the problem, sewer repair can involve spot repairs, pipe lining, or pipe bursting.

Common Sewer Issues

There are several common issues that may necessitate sewer repair or replacement:

Clogged Pipes: Buildup of debris, grease, or foreign objects can cause severe blockages in your sewer lines.
Tree Root Intrusion: Roots from nearby trees can infiltrate and damage sewer pipes, leading to blockages and leaks.
Pipe Corrosion: Older pipes, especially those made of cast iron or galvanized steel, can corrode over time, causing leaks and structural weaknesses.
Bellied Pipes: Sections of the sewer pipe that have sunk or become misaligned, creating a low spot where waste and debris can accumulate.
Leaks and Cracks: Damage from shifting soil, freezing and thawing cycles, or other environmental factors can cause leaks and cracks in your pipes.
Collapsed Pipes: Severe damage can lead to the complete collapse of a section of the sewer line, necessitating immediate repair or replacement.

Our Sewer Replacement and Repair Services

We offer a comprehensive range of sewer replacement and repair services to address all your sewer line issues:

Sewer Line Inspection: Using advanced camera inspection technology, we accurately diagnose the condition of your sewer lines and identify the exact location and cause of any issues.
Traditional Sewer Replacement: This method involves excavating the affected area to remove and replace the damaged section of the sewer pipe. It’s effective for extensive damage but can be disruptive to your property.
Trenchless Sewer Replacement: Trenchless methods, such as pipe bursting and pipe lining, allow for sewer replacement with minimal excavation. These techniques are less invasive and often faster than traditional methods.
- Pipe Bursting: This method involves breaking the old pipe while simultaneously pulling a new pipe into place.
- Pipe Lining: Also known as cured-in-place pipe (CIPP), this technique involves inserting a flexible liner coated with resin into the damaged pipe. The liner is then inflated and cured, creating a new, durable pipe within the old one.
Spot Repairs: For minor issues, we can perform localized repairs to fix leaks, cracks, or small sections of damaged pipe.
Root Removal and Prevention: We remove invasive tree roots and can install root barriers or apply chemical root inhibitors to prevent future intrusion.

 Trustindex verifies that the original source of the review is Google. As a restaurant owner in Seattle, I tend to find it infuriating when tradespeople over charge. It’s a real problem in this city. Knockout was fair and fast. Can’t say how much I appreciate it. I’ll be back for sure.

 Trustindex verifies that the original source of the review is Google. Knockout was great to work with - very courteous, responsive, and fair pricing. Zach came out to cap off a gas line for an appliance we switched to electric. The option was to do it from the inside or from the outside and remove the dedicated pipe altogether. Zach gave reasonable pricing (checked with two other companies) and was able to get the job done right away with expertise and professionalism. Knockout will be our top-choice, first-call for any future pluming needs in our home.

 Trustindex verifies that the original source of the review is Google. Excellent experience. I was considering replacing my water heater back in the spring and Knockout was one of the companies I shortlisted to talk to. Ultimately I decided to wait on replacement, but Knockout was definitely at the top of my list. When my water heater started leaking the other day, I immediately reached out to Knockout, and they were able to get me scheduled the next day! I was given the choice between Bradford White and AOS. Zach came out and did a fantastic job. Friendly but professional; quick and efficient but thorough. Knockout respected the quote I was given a few months back which was very competitive. I strongly recommend this company!

 Trustindex verifies that the original source of the review is Google. I asked these guys about hydrojetting our old sewer line that would occasionally get clogged. Zach showed up and looked at the situation, and after chatting for a bit he figured I could DIY it so I would know how to do it rather than paying every time it happeened. So he showed me a fitting for my pressure washer I could get, and described what to do. I did all that and it worked great, and I saved $850 that it would have cost, and then I knew how to do it going forward. They didn't even charge me. They're super honest guys with a lot of integrity. Definitely recommend them.

 Trustindex verifies that the original source of the review is Google. Zach is a consummate professional. He was thorough, timely, efficient, personable, and diligent. He returned the next day after the job to place a cover on a part, which is something my partner & I wouldn’t have known. Clearly, he has integrity, which in my book is paramount. We emphatically would not recommend anyone else, but him and his team for plumbing jobs. We were beyond pleased with Zach’s skill and caliber. 20/10 ⭐️

 Trustindex verifies that the original source of the review is Google. Zack and his crew replaced my kitchen sink drain after it started leaking. I was really happy with the price, and the speed and quality of their work. It was also easy to get a quote and schedule over the phone. I would definitely hire Knockout Plumbing again in the future!
