7 Key Steps in Sewer Line Repair and Installation

A damaged sewer line can cause major problems if not fixed on time. From slow drains to yard flooding, the signs are often easy to miss until the damage is done. Whether you’re replacing an old system or fixing a broken pipe, it’s important to follow the right steps. For safe and reliable sewer repair in Woodland Hills residents rely on skilled plumbing professionals who understand how to handle every part of the process start to finish.

We’ve broken down the work into simple steps to help you understand what really goes into sewer line repair and installation. Here’s what you should know before starting your project.

1. Initial Inspection and Diagnosis

The first step is a thorough inspection. We start by listening to the problem—slow drains, gurgling toilets, or foul smells. Then, we use video camera tools to check inside the pipes and see exactly where the problem is. This helps us find cracks, blockages, or collapsed sections. With a clear view, we can plan the best fix without guesswork.

2. Planning the Right Repair Method

Once the issue is found, we decide how to fix it. Some jobs only need a small section of pipe replaced. Others might need a full line replacement. We also look at the location—under concrete, near trees, or close to property lines—to choose the safest and fastest method. Planning helps save time and money and avoids unnecessary digging.

3. Getting Permits and Checking Local Codes

Before work begins, we check local plumbing codes and apply for any required permits. It’s important that all repairs or installations follow the law and city rules. We also check for underground utility lines before digging. Doing this step right keeps everyone safe and avoids costly fines later.

4. Digging or Using Trenchless Technology

The next step is exposing the damaged line. For smaller repairs, we may only dig a small access area. In some cases, trenchless technology is used, which avoids heavy digging and keeps your yard mostly untouched. Pipe bursting or pipe lining methods can be great options depending on the condition of the old sewer line.

5. Replacing or Repairing the Pipe

Now, the actual repair or installation takes place. We remove broken sections and install new pipes that match your system. If it's a full replacement, we connect new sewer lines and test everything for proper flow. All fittings and seals are double-checked to avoid future leaks. We use strong, durable materials designed to last for decades.

6. Testing the System

Before covering the area, we test the sewer line to make sure everything works properly. We check water flow, seal strength, and drain function. If the system passes all checks, we move to the final stage. Testing is a key part of the job—it helps catch any small issues before they turn into big problems.

7. Restoring the Work Area

Once everything is fixed, we clean up the site. If there was digging, the ground is leveled and put back in place. Driveways, lawns, or walkways are restored as neatly as possible. We don’t leave until your space looks clean, safe, and ready to use again.
