How Often Is Pipe Replacement Necessary?

We occasionally have people ask us whether or not they need to have their pipes replaced past a certain age. The older the house is, the more likely that this question is going to come up. It’s a fair question, but the truth is that in most cases people don’t ever have to replace the pipes in their home. This isn’t because plumbing pipes are invincible. It’s simply that they last a very long time. Let’s take a look at some of the times when you do probably need to have your pipes replaced.

Lime Scale

Lime scale is a kind of mineral buildup caused by hard water, which is water with an above-average mineral content. If your home is exposed to enough hard water over time, the lime scale buildup can become advanced enough to restrict the flow of water through the pipe. At that point, the only way to remove the lime scale is often to replace the pipe completely.


The main reason that copper is the standard material for plumbing pipes is that it is highly resistant to things like rust. While that increases its lifespan considerably, copper is still vulnerable to other kinds of corrosion. Formicary and pitted corrosion are both very common afflictions that copper pipes have to deal with. Formicary corrosion weakens pipes by eating microscopic holes through the copper, making leaks more likely. Pitted corrosion, on the other hand, opens up leaks by focusing on a very small area of the pipe. Both of these issues can cause a need for pipe replacement, depending on how widespread they are throughout your system.
