Water pressure, corrosion, and the invasion of tree roots are a few factors that cause pipe bursting and damage sewer lines. However, due to their location, it can be challenging to determine if any damage or repairs are needed. 

If there’s a leak in your sewer lines, start looking for a solution before the situation worsens. Some people choose to replace their entire sewer system, which can prove expensive. A complete replacement can also damage the area around the repair. 

You might only need to call a plumber to perform pipe lining on your existing pipe. Drain Doctor Plumbing & Rooter Service is here when you need a professional plumber in West Covina, CA, and the surrounding areas.

Pipe lining is a good option for repairing a damaged sewer pipe system without spending too much and causing extensive property damage. But what are the different types of pipe lining? How long does each type of pipe lining last?

Types of Pipe Lining 

There are four types of pipe lining methods available these days. Here’s a description of each one with how long you can expect the repair to last: 


Cured-in-place piping is a process for repairing trenchless pipe lining. Professional sewer and drain companies line the cracked section of the pipe. 

First, they clean the pipe’s interior without digging a trench. Then, once it dries, they apply lining to the affected areas. Finally, they mold the cracks through jets of hot water, steam, or UV light.

Cured-in-place piping works best for large-diameter lines with high access costs. You can expect this type of pipe repair to last for approximately 50 years.

Pipe Bursting

Pipe bursting is a trenchless sewer line replacement method that breaks pipes. First, the installers dig two four-foot square pits at both tube ends. Then, they place a bursting head dragged through the line with hydraulic power at one access point. 

The lining goes back in, drawing a new seamless pipe and breaking the older one. Then, the installers retrieve the broken head from the second access point. This type of pipe lining can last for up to 100 years.


This technique is most effective for pipes with cracks and wide gaps. The installers need two openings for this procedure — one for inserting the liner and the other for pulling it out. 

In the first opening, the plumbers use steam to drill the liner into the existing pipe. Next, they utilize the second opening to pull the liner through. Then, they use hot air to expand it before allowing it to dry.

Internal Pipe Coating

Internal pipe coating is a relatively straightforward process for repairing. First, the plumber applies epoxy resin inside the pipe or drain to fix cracks, holes, and damage from root intrusion. 

The plumber uses a pump and a flexible metal tube to apply the epoxy resin through the pipe or drain. Then, a rotating brush spreads the epoxy throughout the length of the pipe’s interior. 

This repair method works best for sectional drain fixtures and long pipes. Internal pipe coating usually lasts approximately 40 years.
