Sewer lines are built to last. Just like most of the pipes in your home, sewer lines tend to be made of the metal copper, which is highly resistant to most forms of corrosion and can last up to a century under the right circumstances. There will come a time, however, when the sewer line will need to be replaced. It is important to keep an eye out for signs that your sewer line needs replacing, so that you can limit any resulting problems as much as possible. Let’s take a look at some signs that you need to replace your sewer line.
Frequent Sewage Backups
Sewer lines can have waste build up on the inner walls of the pipes over time, which can eventually form clogs and cause backups. This is typically easily solved by hydro jetting or some other pipe cleaning method. However, if it’s happening quite frequently it might be because of some other reason. Lime scale is a possible cause, as is tree root systems if you have a tree on or near your property. Some of these problems damage the sewer line beyond repair, which means you’ll need to replace it.
Copper is resistant to rust, but that doesn’t mean that it’s immune to all corrosion. Formaldehyde and chlorine particles in the soil can eat away at the copper in the pipes, opening up leaks and eventually causing larger issues like ruptures. Typically, this is indicated by foul-smelling pools forming on your lawn. If the leaks are small enough, you can often just patch the line. Sometimes, though, the corrosion is too advanced and replacement is required.
