If the sewer line in your home is in trouble, you'll probably know it. Your toilet may not flush, or there could even be sewage in your yard. Sewer line repair is probably the last thing you want to deal with, but having a working sewer is essential for health and safety reasons. You might need to replace the entire sewer line or the plumber might just patch the bad area. Here's a look at both of these options.
Look Inside The Pipe To Determine The Damage
A plumber can thread a small camera in the sewer pipe to see what's going on without having to dig up the pipe. If the plumber sees an old pipe that's falling apart, then the old pipe has to be replaced. However, if the plumber sees most of the pipe is in good shape, but a small part has cracked or collapsed, then making repairs might be a possibility.
Replace A Pipe With A Liner Or New Pipe
There are a couple of ways to replace a bad sewer pipe. One involves digging a trench by the old pipe so the old pipe can be lifted out and replaced with a new pipe. This might be too disruptive for you if you have expensive landscaping in your yard or a pool or shed above the pipe.
The other way to replace an old pipe is to pull a liner through the pipe while the pipe is still underground. One way of doing this busts up the old pipe as the new one is pulled through. Another method pulls a liner through the inside of the old pipe, inflates the liner, and leaves both the liner and pipe in place under the ground. The new liner hardens into a new pipe that should last for decades.
Repair A Crack With A Patch
There are also a couple of ways to patch a sewer line that is only damaged in a small area. The damaged area can be repaired by digging down to the pipe or by pulling a patch through the pipe to the cracked area.
Pulling the patch through the inside of the pipe works just like pulling a new liner through, except the patch is just a small section of liner. Once the patch is in place, it sticks to the sides of the pipe and creates a watertight seal. It's possible to find the exact spot of damage, thanks to the pipe camera that locates the area and sends a signal up to the surface of your lawn that the plumber detects.
Another way to patch a pipe is to dig down to the damaged area and patch in a new piece of pipe after cutting out the bad part of the pipe first. Your plumber may not be able to do this will all types of sewer pipes, and you may prefer an internal patch so your yard doesn't have to be dug up.
